10/100/1000 Ports
The 10/100/1000 ports use RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet
(100 meters). The 100BASE-TX and 1000BASE-T traffic requires twisted pair (UTP) cable of Category 5
or higher. The 10BASE-T traffic can use Category 3 cable or higher.
PoE and PoE+ Ports
The PoE and PoE+ ports provide the following functionality:
• PoE/PoE+ ports: Support for IEEE 802.3af-compliant powered devices (up to 15.4W PoE per port) and
support for IEEE 802.3at-compliant powered devices (up to 30W PoE+ per port).
• Support for pre-standard Cisco powered devices.
• Configurable support for Cisco intelligent power management, including enhanced power negotiation,
power reservation, and per-port power policing.
Cisco Catalyst 9200 Series Switches Hardware Installation Guide

Product Overview
10/100/1000 Ports
See the Power Supply Modules, on page 9 for the power supply matrix that defines the available PoE and
PoE+ power per port. The PoE circuit has been evaluated to meet the limits for Limited Power Source (LPS)
per Annex Q in IEC/UL 62368-1. It has also been evaluated as a class ES1, PS2.
Multigigabit Ethernet Ports
The Multigigabit (mGig) Ethernet ports can be configured to auto-negotiate multiple speeds on switch ports.
The ports support 100 Mbps, 1 Gbps, 2.5 Gbps, and 5 Gbps speeds on Category 5e (Cat5e) cables, and up to
10 Gbps over Category 6 (Cat6) and Category 6A (Cat6A) cables up to a maximum of 100 m. 10Gbps over
Cat6 cable is limited for distances up to 55 m. For 10GBASE-T, Cat6a can support up to 100 m when
transmitting 10Gbps. Due to the extra bandwidth requirements from the cable, additional limitations exist for
best performance. These limitations include, but are not limited to cable reach, cable bundling parameters
(tightness, frequency, number of cables, speed with respect to each cable) and cable termination quality.
The 802.3 channel requirements for interoperability typically limit the cable reach to 100 m, but other factors
can shorten this reach. In addition, for both Cisco UPOE and Cisco UPOE+ and data integrity, the 100 m total
should not include more than 10 m total stranded or patch cable. Therefore, it is assumed that a 100 m link
includes a maximum of two 5 m patch cables of the appropriate category, and 90 m of plenum or riser (i.e.
solid copper core) cables. Ensure that you follow the TIA guidance on cable dressing.
It is recommended to test the complete link using an appropriate cable tester for 10 Gbps as well as 5 Gbps
links. However, even if the link passes cable testing, it is still prone to occasional errors due to aggressors in
the bundle, and physical disturbances of the cables. As an example of bundling limitations, for 5 Gbps with
cat5e cable, only a total 45 m bundled length is supported; the remaining 55 m should be unbundled. For
bundling, follow Cisco Guidelines and Best Practices for the Installation and Maintenance of Data Networking
Equipment which recommends the use of Velcro ties every 1 to 2 m for bundled sections.
If you are upgrading the network gear but reusing the existing cable plant, note that at speeds above 2.5 Gbps
traditional Cat5e channel specifications do not support full 100 m reach. To ensure 5 Gbps link speeds, we
recommend using Cat6a cabling. For more information, see the Whitepaper from NBASE-T alliance, which
has now merged with Ethernet Alliance, archived at
https://archive.nbaset.ethernetalliance.org/library/white-paper-2/.
Multigigabit ports do not support half duplex mode. Use full duplex mode.
Note
Management Ports
The management ports connect the switch to a PC running Microsoft Windows or to a terminal server.
• Ethernet management port. See Ethernet Management Port, on page 13.
• RJ-45 console port (EIA/TIA-232). See RJ-45 Console Port, on page 13.
• USB mini-Type B console port (5-pin connector).
The 10/100/1000 Ethernet management port connection uses a standard RJ-45 crossover or straight-through
cable. The RJ-45 console port connection uses the supplied RJ-45-to-DB-9 female cable. The USB console
port connection uses a USB Type A to 5-pin mini-Type B cable. The USB console interface speeds are the
same as the RJ-45 console interface speeds.
Cisco Catalyst 9200 Series Switches Hardware Installation Guide

Product Overview
Multigigabit Ethernet Ports
If you use the USB mini-Type B console port, the Cisco Windows USB device driver must be installed on
any PC connected to the console port (for operation with Microsoft Windows). Mac OS X or Linux do not
require special drivers.
The 4-pin mini-Type B connector resembles the 5-pin mini-Type B connectors. They are not compatible. Use
only the 5-pin mini-Type B.
Figure 1: USB Mini-Type B Port
This illustration shows a 5-pin mini-Type B USB port.
With the Cisco Windows USB device driver, you can connect and disconnect the USB cable from the console
port without affecting Windows HyperTerminal operations.
The console output always goes to both the RJ-45 and the USB console connectors, but the console input is
active on only one of the console connectors at any one time. The USB console takes precedence over the
RJ-45 console. When a cable is connected into the USB console port, the RJ-45 console port becomes inactive.
Conversely, when the USB cable is disconnected from the USB console port, the RJ-45 port becomes active.
You can use the command-line interface (CLI) to configure an inactivity timeout which reactivates the RJ-45
console if the USB console has been activated and no input activity has occurred on the USB console for a
specified time.
After the USB console deactivates due to inactivity, you cannot use the CLI to reactivate it. Disconnect and
reconnect the USB cable to reactivate the USB console. For information on using the CLI to configure the
USB console interface, see the Software Configuration Guide.
USB Type A Port
The USB Type A port provides access to external USB flash devices (also known as thumb drives or USB
keys).
The port supports Cisco USB flash drives with capacities from 128 MB to 8 GB. USB devices with port
densities of 128 MB, 256 MB, 1 GB, 4 GB, and 8 GB are supported. When combined with stacking, you can
upgrade other switches in the stack from an USB key inserted in any switch within the stack. Cisco IOS
software provides standard file system access to the flash device: read, write, erase, and copy, as well as the
ability to format the flash device with a FAT file system.
It provides you with the ability to automatically upgrade the internal flash with the USB drive's configuration
and image for emergency switch recovery using USB auto-upgrade. This feature checks the internal flash for
a bootable image and configuration and if either image or the configuration is not available, then the USB
drive is checked for boot images and configuration. If the boot image and configuration are available, these
are copied to flash for the reboot.
Uplink Ports
The Cisco Catalyst 9200 Series switches support both fixed uplinks and modular uplinks. The C9200 switch
models support modular uplinks with one hot-swappable network module that provides uplink ports to connect
to other devices.
The fixed uplink ports on C9200L switch models support the following types of transceiver modules.
• 4x1G ports that support 1G SFP modules.
Cisco Catalyst 9200 Series Switches Hardware Installation Guide

Product Overview
USB Type A Port
• 4x10G ports that support either 1G SFP or 10G SFP+ modules.
• 2x25G ports that support SFP28 modules.

RFID Tag
The switch has a built-in, front-facing, passive RFID tag that uses UHF RFID technology and requires an
RFID reader with compatible software. It provides auto-identification capabilities for asset management and
tracking. The RFID tags are compatible with the Generation 2 GS1 EPC Global Standard and are ISO 18000-6C
compliant. They operate in the 860- to 960-MHz UHF band. For more information, see Radio Frequency
Identification (RFID) on Cisco Catalyst 9000 Family Switches White Paper.
StackWise Ports
StackWise ports are used to connect switches in StackWise stacking configurations. The switch ships with a
0.5-meter StackWise cable that you can use to connect the StackWise ports. For more information on StackWise
cables, see Connecting to the StackWise Ports, on page 39.
Use only approved cables, and connect only to similar Cisco equipment. Equipment might be damaged if
connected to nonapproved Cisco cables or equipment.
Caution
Power Supply Modules
The switch has a field replaceable main AC power supply module and a redundant hot-swappable field
replaceable AC power supply module. The switch is powered through one or two internal power supply
modules. In switches with PoE capability, the redundant power supply can also be used for extra PoE power.
The following are the power supply modules supported on Cisco Catalyst 9200 Series Switches:

• PWR-C5-1KWAC
• PWR-C6-125WAC
• PWR-C6-600WAC
• PWR-C6-715WDC=
• PWR-C6-1KWAC
The switch has two internal power supply module slots. You can use two AC power supply modules or one
power supply module and a blank module (PWR-C5-BLANK).
The switch can operate with either one or two active power supply modules.
Switch Models, on page 1 shows the default power supply modules that ship with each switch model. All
power supply modules (except the blank modules) have internal fans. All switches ship with a blank power
supply module in the second power supply slot. Each AC power supply module has a power cord
(CAB-TA-XXX) for connection to an AC power outlet.
Do not operate the switch with one power supply module slot empty. For proper chassis cooling, both power
supply module slots must be populated with either a power supply or a blank module.
Caution
The power supply modules are autoranging units that support input voltages between 100 and 240 VAC. The
output voltage range is 12 to 12.5 V for 125W power supply and 54 to 56 V for 600W and 1000W power
supplies.
All the PoE-enabled switches when installed with both the power supplies support full PoE+; 1440W on a
48-port switch and 740W on a 24-port switch. The partial PoE-enabled switches support only 600W power
supply providing a PoE budget of 370W. If the switch is installed with one power supply, the available POE
budget is 370W and 740W, if there are two power supplies installed.
The following tables show the PoE available and PoE requirements for PoE switch models.

Fan Modules
The Cisco Catalyst 9200 Series Switches supports two internal fixed 12-V fan modules and two field-replaceable
fan modules (C9200-FAN=). The C9200 models support modular fans whereas the C9200L models provide
two internal fixed fans.
For information about the type of fan module supported on different switch models, see Switch Models, on
page 1.

Product Overview
Fan Modules
The air circulation system consists of the fan modules and the power supply modules. The airflow patterns
vary depending on the power supply configuration. The switch can operate at ambient temperature if one of
the fans fail.
Figure 5: Switch Airflow Pattern
The following illustration shows the airflow pattern for the switches. The blue arrow shows cool airflow, and
the red arrow shows warm airflow.
Ethernet Management Port
You can connect the switch to a host such as a Windows workstation or a terminal server through the
10/100/1000 Ethernet management port or one of the console ports. The 10/100/1000 Ethernet out-of-band
management port is a virtual routing and forwarding (VRF) interface and uses a RJ-45 crossover or
straight-through cable.
The 10/100/1000 Ethernet management port is an RJ-45 connector that should be connected to a Windows
workstation or a terminal server. Do not connect this port to another port in the same switch or to any port
within the same switch stack.

Installation Guidelines
When determining where to install the switch, verify that these guidelines are met:
• Clearance to the switch front and rear panel meets these conditions:
• Front-panel LEDs can be easily read.
• Access to ports is sufficient for unrestricted cabling.
• AC power cord can reach from the AC power outlet to the connector on the switch rear panel.
• The SFP/SFP+ module minimum bend radius and connector length is met. See the SFP/SFP+ module
documentation for more information.
• Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting
fixtures. Make sure that the cabling is safely away from other devices that might damage the cables.
• Make sure power-supply modules and fan modules are securely inserted in the chassis before moving
the switch.
• Airflow around the switch and through the vents is unrestricted. For more information, see Air Flow.
• For copper connections on Ethernet ports, cable lengths from the switch to connected devices can be up
to 328 feet (100 meters).
• Temperature around the unit does not exceed 113°F (45°C). If the switch is installed in a closed or
multirack assembly, the temperature around it might be greater than normal room temperature. For more
information, see Temperature.
• Humidity around the switch does not exceed 95 percent. For more information, see Humidity.
• Altitude at the installation site is not greater than 10,000 feet. For more information, see Altitude.
• Cooling mechanisms, such as fans and blowers in the switch, can draw dust and other particles causing
contaminant buildup inside the chassis, which can result in system malfunction. You must install this
equipment in an environment as free from dust and foreign conductive material (such as metal flakes
from construction activities) as possible. For more information, see Air Quality and Corrosion.
For more information on choosing a location for the switch installation, see Site Requirements.
The illustrations used in this section shows a C9200L switch. The C9200 switch installation is similar to
C9200L, follow the same steps for installing C9200 switches.
Note
Site Requirements
Planning a proper location for the switch and layout of the equipment rack or wiring closet is essential for
successful system operation. These sections describe some of the basic site requirements that you should be
aware of as you prepare to install your switch, including the following:
• Environmental factors can adversely affect the performance and longevity of your system.
Cisco Catalyst 9200 Series Switches Hardware Installation Guide
17
Preparing for Installation
Installation Guidelines
• Install the switch in an enclosed, secure area, ensuring that only qualified personnel have access to the
switch and control of the environment.
• Equipment that is placed too closely together or that is inadequately ventilated may cause system
over-temperature conditions, leading to premature component failure.
• Poor equipment placement can make chassis panels inaccessible and difficult to maintain.
• The switch requires a dry, clean, well-ventilated, and air-conditioned environment.
• To ensure normal operation, maintain ambient airflow. If the airflow is blocked or restricted, or if the
intake air is too warm, an over-temperature condition may occur. The switch environmental monitor may
then shut down the system to protect the system components.
• Multiple switches can be rack mounted with little or no clearance above and below the chassis. However,
when mounting a switch in a rack with other equipment, or when placing it on the floor near other
equipment, ensure that the exhaust from other equipment does not blow into the air intake vent of the
switch chassis.
Temperature
Temperature extremes may cause a system to operate at reduced efficiency and cause a variety of problems,
including premature aging and failure of chips, and failure of mechanical devices. Extreme temperature
fluctuations may also cause chips to become loose in their sockets. Observe the following guidelines:
• Ensure that the chassis has adequate ventilation.
• Do not place the chassis within a closed-in wall unit or on top of cloth, which can act as thermal insulation.
• Do not place the chassis where it will receive direct sunlight, particularly in the afternoon.
• Do not place the chassis next to a heat source of any kind, including heating vents.
• Adequate ventilation is particularly important at high altitudes. Make sure that all the slots and openings
on the system remain unobstructed, especially the fan vent on the chassis.
• Clean the installation site at regular intervals to avoid buildup of dust and debris, which may cause a
system to overheat.
• If system is exposed to abnormally low temperatures, allow a two hour warm up period, in ambient
temperature no lower than 32°F (0 °C) before turning on.
Failure to observe these guidelines may damage the chassis' internal components.
Air Flow
The switch is designed to be installed in an environment where there is a sufficient volume of air available to
cool the supervisor engines, modules, and power supplies. If there are any constraints with regard to the free
flow of air through the chassis, or if the ambient air temperature is elevated, the switch environmental monitor
may then shut down the system to protect the system components.
To maintain proper air circulation through the switch chassis, we recommend that you maintain a minimum
space of 6 inches (15 cm) between a wall and the chassis and power supply unit air intakes or a wall and the
chassis and power supply unit hot air exhausts. In situations where the switch chassis are installed in adjacent
racks, you should allow a minimum space of 12 inches (30.5 cm) between the air intake of one chassis and
Cisco Catalyst 9200 Series Switches Hardware Installation Guide
18
Preparing for Installation
Temperature
the hot air exhaust of another chassis. Failure to maintain adequate spacing between chassis may cause the
switch chassis that is drawing in the hot exhaust air to overheat and fail.
If you are installing your switch in an enclosed or partially enclosed rack, we strongly recommend that you
verify that your site meets the following guidelines:
• Verify that the ambient air temperature within the enclosed or partially enclosed rack is within the chassis
operating temperature limits. After installing the chassis in the rack, power up the chassis and allow the
chassis temperature to stabilize (approximately 2 hours).
Measure the ambient air temperature at the chassis air intake grill by positioning an external temperature
probe 1 inch (2.5 cm) away from the chassis left side, and centered on the chassis both horizontally and
vertically.
Measure the ambient air temperature at the power supply unit air intake grill by positioning an external
temperature probe 1 inch (2.5 cm) away from the chassis front, centered on the power supply unit section
located above the card slots.
• If the ambient intake air temperature is less than 109°F (45°C) at altitudes of 6,000 feet and below,
the rack meets the intake air temperature criterion. At altitudes above that threshold and up to 10,000
feet (3000 m), the air intake should not exceed 104°F (40°C).
• If the ambient intake air temperature exceeds this recommendation, the system may experience
minor temperature alarms and increase fan speeds in response.
• If the ambient intake air temperature equals or is greater than 131°F (55°C), the system may
experience a major temperature alarm with maximum fan speeds in response. If ambient temperature
continues to increase, system will respond with protective shut down.
• Plan ahead. A switch that is currently installed in an enclosed or partially enclosed rack might meet
ambient air temperature and air flow requirements at present. However, if you add more chassis to the
rack or more modules to a chassis in the rack, the additional heat generated might cause the ambient air
temperature at the chassis or power supply unit inlets to exceed recommended conditions which may
trigger thermal alarms.
If installation conditions for inlet temperature and airflow are marginal or not fully met, activate the fan
tray’s NEBS mode, which has more aggressive programming to address restricted spacing and elevated
ambient temperatures. This should result in reduced thermal alarms along with greater acoustic noise
and increased power consumption associated with higher fan speeds.
Humidity
High-humidity conditions may cause moisture to enter the system, and cause corrosion of internal components
and degradation of properties such as electrical resistance, thermal conductivity, physical strength, and size.
Extreme moisture buildup inside the system may result in electrical short circuit, which may cause serious
damage to the system. Each system is rated for storage and operation in 10 to 95 percent relative humidity,
non-condensing with a humidity gradation of 10 percent per hour. Buildings in which climate is controlled
by air-conditioning in the warmer months and by heat during the colder months usually maintain an acceptable
level of humidity for system equipment. However, if a system is located in an unusually humid location, a
dehumidifier should be used to maintain the humidity within an acceptable range.
Cisco Catalyst 9200 Series Switches Hardware Installation Guide
19
Preparing for Installation
Humidity
Altitude
Operating a system at high altitude (low pressure) reduces the efficiency of forced and convection cooling
and may result in electrical problems related to arcing and corona effects. This condition may also cause sealed
components with internal pressure, such as electrolytic capacitors, to fail or perform at reduced efficiency.
Dust and Particles
Fans cool power supplies and system components by drawing in room-temperature air and exhausting heated
air out through various openings in the chassis. However, fans also ingest dust and other particles, causing
contaminant buildup in the system and increased internal chassis temperature. A clean operating environment
can greatly reduce the negative effects of dust and other particles, which act as insulators and interfere with
the mechanical components in the system.
The standards listed below provide guidelines for acceptable working environments and acceptable levels of
suspended particulate matter:
• National Electrical Manufacturers Association (NEMA) Type 1
• International Electrotechnical Commission (IEC) IP-20
Air Quality
Dust is everywhere and often invisible to the naked eye. It consists of fine particles in the air that originate
from various sources, such as soil dust lifted by weather, from volcanic eruptions, or pollution. Dust at an
installation site may contain small amounts of textile, paper fibers, or minerals from outdoor soil. It may also
contain natural contaminants, such as chlorine from the marine environment and industrial contaminants such
as sulfur. Ionized dust and debris are dangerous and get attracted to electronic equipment.
The accumulation of dust and debris on electronic equipment has the following adverse effects:
• It increases the operating temperature of the equipment. According to the Arrhenius effect, an increase
in the operating temperature leads to a decrease in reliability and life of the equipment.
• The moisture and corrosive elements that are present in the dust can corrode the electronic or mechanical
components and cause premature board failure.
These adverse effects are further accelerated by the presence of fans in the data networking equipment that
ingest dust and other particles into the equipment. Higher the volume of air that is generated by the fans for
cooling, the higher the quantity of dust and particulates that get deposited and trapped inside the equipment.
Remove or minimize the presence of dust and particulates at the installation site by following the guidelines
mentioned in ANSI 71-04-2013 regulations.
In addition to the guidelines mentioned in ANSI 71-04-2013 regulations, follow all applicable guidelines as
per site conditions to remove or minimize other contaminants.

Corrosion
Corrosion is a chemical reaction that occurs between electronic components and gases which results in metal
deterioration. Corrosion attacks edge connectors, pin connectors, IC plug-in sockets, wirewraps, and all other
metal components. Depending on the type and concentration level of the corrosive gases, performance
degradation of the components occurs either rapidly or over a period of time. It also leads to blocked currents,
brittle connection points, and overheated electrical systems. Corrosion by-products form insulating layers on
circuits and causes electronic failure, short circuits, pitting, and metal loss.
A type of corrosion known as creep corrosion, that primarily affects PCBA (Printed Circuit Board Assembly)
occurs when the PCBA is subjected to a harsh, and sulfur-rich (hydrogen sulfide) end-use environment over
a prolonged period of time. The corrosion begins on certain exposed metals, such as copper and silver, and
then creeps along the remaining metal surface either causing electrical short circuits or creating holes. Creep
corrosion also occurs on electronic components such as resistors and PCBs.
To prevent corrosion, remove or minimize the presence of dust and particulates at the installation site by
following the guidelines mentioned in ANSI 71-04-2013 regulations.

EMI and Radio Frequency Interference
Electro-Magnetic interference (EMI) and radio frequency interference (RFI) from a system can adversely
affect devices such as radio and television (TV) receivers operating near the system. Radio frequencies
emanating from a system can also interfere with cordless and low-power telephones. Conversely, RFI from
high-power telephones can cause spurious characters to appear on the system monitor. RFI is defined as any
EMI with a frequency above 10 kilohertz (kHz). This type of interference can travel from the system to other
devices through the power cable and power source, or through the air in the form of transmitted radio waves.
The Federal Communications Commission (FCC) publishes specific regulations to limit the amount of harmful
interference emitted by computing equipment. Each system meets these FCC regulations. To reduce the
possibility of EMI and RFI, follow these guidelines:
• Always operate the system with the chassis covers installed.
• Ensure that all chassis slots are covered by a metal filler bracket and that an unused power supply bay
has a metal cover plate installed.
• Ensure that the screws on all peripheral cable connectors are securely fastened to their corresponding
connectors on the back of the chassis.
• Always use shielded cables with metal connector shells for attaching peripherals to the system.
When wires are run for any significant distance in an electromagnetic field, interference can occur between
the field and the signals on the wires. This fact has two implications for the construction of plant wiring:
• Bad wiring practice can result in radio interference emanating from the plant wiring.
• Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers
and receivers in the chassis, and even create an electrical hazard by conducting power surges through
lines into equipment.
To predict and provide a remedy for strong EMI, consult experts in RFI.
Note
Higher-bandwidth twisted-pair cable and lower-loss connections, will result in better signal-to-noise ratio.
This higher-quality connection is more immune to the RF noise and also allows data transmission over longer
cable distances. Uninterrupted connections are preferred over breakouts and cable couplers.
Electromagnetic pulse caused by lightning or other high-energy phenomena can easily couple enough energy
into the unshielded conductors to destroy electronic devices. Ground potential rise can cause similar damage
when using poorly-shielded or poorly-terminated cables. A 360-degree shield and termination will greatly
reduce or eliminate these effects on shielded cables. If you have had problems of this sort in the past, you
may want to consult experts in electrical surge suppression and shielding.
Shock and Vibration
The equipment is designed for Earthquake, Office, and Transportation Vibration, and Equipment Handling.
Power Source Interruptions
The greatest threats to a system's power supply are surges or blackouts that are caused by electrical storms.
Whenever possible, turn off the system and peripherals, if any, and unplug them from their power sources
Cisco Catalyst 9200 Series Switches Hardware Installation Guide
22
Preparing for Installation
EMI and Radio Frequency Interference
during thunderstorms. If a blackout occurs—even a temporary one—while the system is turned on, turn off
the system immediately and disconnect it from the electrical outlet. Leaving the system on may cause problems
when the power is restored; turning on all appliances left on in the area at the same time may cause unsustainable
inrush current demand on the power grid.
System Grounding
Proper grounding practices ensure that the buildings and the installed equipment within them have
low-impedance ground connections and low-voltage differentials between chassis. When you install a system
ground, you reduce or prevent shock hazards, chances of equipment damage due to transients, and the potential
for data corruption.
Chassis AC third-prong ground, and third-ground wire on the DC input is considered sufficient for these units.
The following table lists some general grounding practice guidelines.

Note
Maintaining Safety with Electricity
When working on electrical equipment, follow these guidelines:
• Do not work alone if potentially hazardous conditions exist anywhere in your work space.
• Never assume that power is disconnected from a circuit; always check the circuit before working on it.
• When the power is switched off, put a lock-box on the circuit, so that no one can accidentally switch it
on.
• Look carefully for possible hazards in your work area, such as damp floors, ungrounded power extension
cables, frayed or damaged power cords, and missing safety grounds.
• If an electrical accident occurs, proceed as follows:
• Use extreme caution; do not become a victim yourself.
• Disconnect power from the system.
• Seek medical attention, if necessary.
• Use the product within its marked electrical ratings and product usage instructions.
• Install the product in compliance with local and national electrical codes.
Cisco Catalyst 9200 Series Switches Hardware Installation Guide

Preparing for Installation
Maintaining Safety with Electricity
• If any of the following conditions occur, contact the Cisco Technical Assistance Center:
• The power cable or plug is damaged.
• An object has fallen into the product.
• The product has been exposed to water or other liquids.
• The product has been dropped or shows signs of damage.
• The product does not operate correctly when you follow the operating instructions.
• Use the correct external power source. Operate the product only from the type of power source indicated
on the electrical ratings label. If you are not sure of the type of power source required, consult a local
electrician.
• To help prevent electrical shock, plug all the power cables into properly grounded electrical outlets.
These power cables are equipped with three-prong plugs to ensure proper grounding. Do not use adapter
plugs or remove the grounding prong from a power cable.
• Observe power strip ratings. Make sure that the total current rating of all products that are plugged into
the power strip does not exceed 80 percent of the power strip rating.
• Do not modify power cables or plugs yourself. Consult with a licensed electrician or your power company
for site modifications. Always follow your local and national wiring codes.
Preventing ESD Damage
ESD damage might occur when modules or other FRUs are improperly handled, resulting in intermittent or
complete failure of the modules or FRUs. Modules consist of printed circuit boards that are fixed in metal
carriers. EMI shielding and connectors are integral components of a carrier. Although the metal carrier helps
to protect the board from ESD, always use an ESD-grounding strap when handling modules. To prevent ESD
damage, follow these guidelines:
• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
• Connect the equipment end of the strap to an unfinished chassis surface.
• When installing a component, use an available ejector lever to properly seat the bus connectors in the
backplane or midplane. These devices prevent accidental removal, provide proper grounding for the
system, and help to ensure that bus connectors are properly seated.
• When removing a component, use an available ejector lever to release the bus connectors from the
backplane or midplane.
• Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.
• Place a removed component board-side-up on an antistatic surface or in a static-shielding container. If
you plan to return the component to the factory, immediately place it in a static-shielding container.
• Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components
from ESD voltages on the body; ESD voltages on clothing can still cause damage.
• Never attempt to remove the printed circuit board from the metal carrier.

Verifying Switch Operation
Before you install the switch in a rack or on a table or shelf, power on the switch and verify that it passes
POST.
To power on the switch, plug one end of the AC power cord into the switch AC power connector, and plug
the other end into an AC power outlet.
As the switch powers on, it begins the POST, a series of tests that runs automatically to ensure that the switch
functions properly. LEDs can blink during the test. POST lasts approximately 1 minute. The SYST LED
blinks green, and the other LEDs remain solid green.
When the switch completes POST successfully, the SYST LED remains green. The LEDs turn off and then
reflect the switch operating status. If a switch fails POST, the SYST LED turns amber.
POST failures are usually fatal. Call Cisco technical support representative if your switch fails POST.
After a successful POST, unplug the power cord from the switch and install the switch in a rack, on a table,
or on a shelf.

Planning a Switch Data Stack
• Number of switches in the stack. You can create data stacks with up to eight switches in a stack.
• Length of the cable. Order the appropriate cable from your Cisco sales representative. The length of the
cable depends on your configuration. These are the different sizes available:
• 0.5 meter cable (STACK-T4-50CM)
• 1 meter cable (STACK-T4-1M)
• 3 meter cable (STACK-T4-3M)

Data Stack Bandwidth and Partitioning Examples
This figure shows an example of a stack of switches with incomplete StackWise cabling connections. This
stack provides only half bandwidth and does not have redundant connections.
Figure 11: Example of a Data Stack with Half Bandwidth Connections
The figures below show data stacks of switches with failover conditions. In this figure, the StackWise cable
is bad in link 2. Therefore, this stack provides only half bandwidth and does not have redundant connections.
Figure 12: Example of a Data Stack with a Failover Condition
In this figure, link 2 is bad. Therefore, this stack partitions into two stacks, and the top and bottom switches
become the active switch in the stack. If the bottom switch is a member (not active or standby switch), it
reloads.

Power-On Sequence for Switch Stacks
Consider these guidelines before you power on the switches in a stack:
• The sequence in which the switches are first powered on might affect the switch that becomes the stack
master.
• There are two ways to elect an active switch:
• If you want a particular switch to become the active switch, configure it with the highest priority.
Among switches with same priority, the switch with the lowest MAC address becomes the active
switch.
• If you want a particular switch to become the active switch, power on that switch first. This switch
remains the active switch until a reelection is required. After 2 minutes, power on the other switches
in the stack. If you have no preference as to which switch becomes the active switch, power on all
the switches in the stack within 1 minute. These switches participate in the active switch election.
Switches powered on after 2 minutes do not participate in the election.
• Power off a switch before you add it to or remove it from an existing switch stack. If changes are made
to the stack without powering down the switches, the following results can occur:
• If two operating partial ring stacks are connected together using a stack cable, a stack merge can
take place. This situation reloads the whole stack (all switches in the stack).
• If some switches in the stack are completely separated from the stack, a stack split can occur.
• A stack split can occur on a full ring stack if:
• More than one running switch is removed without powering down.
• More than one stack cable is removed without powering down.
• A stack split can occur in a partial ring stack if:
• A switch is removed without powering down.
Cisco Catalyst 9200 Series Switches Hardware Installation Guide
33
Installing the Switch
Power-On Sequence for Switch Stacks
• A stack cable is removed without powering down.
• In a split stack, depending on where the active and standby switches are located, either two stacks might
be formed (with the standby taking over as the new active switch in the newly formed stack) or all the
members in the newly formed stack might reload.
These results depend on how the switches are connected. You can remove two or more switches from the
stack without splitting the stack.
Note
For conditions that can cause a stack reelection or to manually elect the active switch, see the stacking software
configuration guide Stack Managerand High Availability Configuration Guide for Cisco Catalyst 9200 Series
Switches on Cisco.com.
Mounting the Switch
The following sections explain the different mounting options.
Rack-Mounting
Installation in racks other than 19-inch racks requires a bracket kit not included with the switch.
To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to
ensure that the system remains stable. The following guidelines are provided to ensure your safety:
• This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
• When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the
heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the
unit in the rack.

After Switch Installation
Connecting to the StackWise Ports
Before you begin
Before connecting the StackWise cables, read the "Planning a Switch Data Stack" section. Always use a
Cisco-approved StackWise cable to connect the switches.
Procedure
Step 1 Remove the dust covers from the StackWise cables and StackWise ports, and store them for future use.
A StackWise adapter must be installed in the StackWise port to enable stacking. In the default setup, the
StackWise adapter blanks are installed in the StackWise ports. If StackWise stacking is ordered with the
switch, StackWise adapters are already installed in the StackWise ports, and you can proceed to step 4.
Step 2 Remove the StackWise adapter blanks from each destination StackWise port using the Torx T15 Allen key
provided in the stacking kit (or a Torx T15 screwdriver). Store them for future use.
Step 3 Install a StackWise adapter in each destination StackWise port, and secure it in place using the supplied Torx
T15 key, or a Torx T15 screwdriver.
Figure 19: Installing the StackWise Adapter in a StackWise Port
StackWise port2StackWise adapter1
Step 4 Connect the cable to the StackWise port on the switch rear panel.
a) Align the StackWise cable connector with the StackWise adapter in the StackWise port.
b) Insert the StackWise cable connector into the StackWise port. Make sure that the Cisco logo is on the top
side of the connector.

c) Finger-tighten the screws in clockwise direction.
Step 5 Connect the other end of the cable to the port on the other switch and finger-tighten the screws. Avoid
over-tightening the screws.
Removing and installing the StackWise cable can shorten its useful life. Do not remove and insert the
cable more often than is absolutely necessary (installing and removing it up to 200 times is supported).
Caution
When you need to remove the StackWise cable from the connector, make sure to fully unscrew the correct
screws. When the connectors are not being used, replace the dust covers.

manually set can reduce performance or result in no linkage.
To maximize performance, choose one of these methods for configuring the Ethernet ports:
• Let the ports autonegotiate both speed and duplex.
• Set the interface speed and duplex parameters on both ends of the connection.
Auto-MDIX Connections
The autonegotiation and the auto-MDIX features are enabled by default on the switch.
With autonegotiation, the switch port configurations change to operate at the speed of the attached device. If
the attached device does not support autonegotiation, you can manually set the switch interface speed and
duplex parameters.
With auto-MDIX, the switch detects the required cable type for copper Ethernet connections and configures
the interface accordingly.
If auto-MDIX is disabled, use the guidelines in this table to select the correct cable.

Safety Warnings
This section includes the installation cautions and warnings. Translations of the safety warnings are available
in the Regulatory Compliance and Safety Information for Cisco Catalyst 9200 Series Switches .
Read this section before you install a network module.
Proper ESD protection is required whenever you handle equipment. Installation and maintenance personnel
should be properly grounded by grounding straps to eliminate the risk of ESD damage to the equipment.
Equipment is subject to ESD damage whenever you remove it.
Caution
Installing a Network Module
The switch can operate without a network module, but a blank module (with no ports or SFP slots) is available
and should be installed when uplink ports are not required.
Note
The switch generates logs when you insert or remove a network module with SFP/SFP+ slots.
Note
Use only supported network modules and Cisco pluggable transceivers. Each module has an internal serial
EEPROM that is encoded with security information.
Cisco Catalyst 9200 Series Switches Hardware Installation Guide
43
The network module is hot-swappable. If you remove a module, replace it with another network module or
a blank module.
The switch complies with EMC, safety, and thermal specifications when a network module is present. If no
uplink ports are required, install a blank network module.
Note
Before you begin
When installing network modules, observe these precautions:
• Do not remove the blank module from the slot unless you are installing a network module. A module
must be in the uplink slot at all times.
• Do not remove the dust plugs from the pluggable transceivers or the rubber caps from the fiber-optic
cable until you connect the cable. The plugs and caps protect the module ports and cables from
contamination and ambient light.
• Removing and installing a network module can shorten its useful life. Do not remove and insert a network
module more often than is necessary.
• To prevent ESD damage, follow your normal board and component handling procedures when connecting
cables to the switch and other devices.

Power Supply Modules Overview
The switch chassis has two power supply slots that operates with either one active power supply module and
a redundant power supply module. You can use two AC modules or one AC module and a blank cover. The
active and redundant modules must be of the same type.
All power supply modules have internal fans. All switches ship with a blank cover in the second power supply
slot.
The main module is field replaceable and the redundant module is hot-swappable. The redundant power supply
can also be used for extra PoE power.
Two power supply modules can be powered up from two different phases.
The following table describes the supported internal power supply modules.

Installation Guidelines
Observe these guidelines when removing or installing a power supply module.
• Do not force the power supply module into the slot. This can damage the pins on the switch if they are
not aligned with the module.
• A power supply module that is only partially connected to the switch can disrupt the system operation.
• Remove power from the power supply module before removing or installing the module.
• The power supply module is hot-swappable. In some configurations, such as full PoE+ or power sharing
mode, removing a power supply module causes powered devices to shut down until the power budget
matches the input power of a single power supply module. To minimize network interruption, ensure
that an active backup is in progress.
For the switch commands that display available power budget, see the software configuration guide.
Cisco Catalyst 9200 Series Switches Hardware Installation Guide
57
Installing a Power Supply Unit
Installation Guidelines
Do not operate the switch with one power-supply module slot empty. For proper chassis cooling, both module
slots must be populated, with either a power supply or a blank module.
Caution
This equipment must be grounded. To reduce the risk of electric shock, never defeat the ground conductor or
operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical
inspection authority or an electrician if you are uncertain that suitable grounding is available.
Warning
Blank faceplates and cover panels serve three important functions: they reduce the risk of electric shock and
fire, they contain electromagnetic interference (EMI) that might disrupt other equipment, and they direct the
flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers,
and rear covers are in place.
Warning

configuration guide. In the guide, go to Configuring the Switch Using the Web User Interface.
Configuring the Switch Using the CLI
Accessing the CLI Through the Console Port
You can access the CLI on a configured or unconfigured switch by connecting the RJ-45 console port or USB
console port of the switch to your PC or workstation and accessing the switch through a terminal emulation
program.
If you have stacked your switches, connect to the console port of one of the switches in the stack. You can
initially configure the entire stack from any member switch.
Note
Connecting the RJ45 Console Port
Procedure
Step 1 Connect the RJ45 port adapter to the serial port on the terminal server or your PC using the optional
RJ45-to-DB9 adapter cable. Connect the other end of the cable to the switch console port.
Step 2 Start the terminal-emulation program on the PC or the terminal. The program, frequently a PC application
such as Putty or TeraTerm, makes communication between the switch and your PC or terminal possible.
Step 3 Configure the baud rate and character format of the PC or terminal to match the console port default
characteristics:

PoE+ is on. The port LED is green when the switch port
is providing power.
Green
PoE+ is denied because providing power to the powered
device will exceed the switch power capacity.
Alternating green-amber
PoE+ is off due to a fault or because it has exceeded a
limit set in the switch software.
PoE+ faults occur when noncompliant cabling or
powered devices are connected to a PoE+ port.
Use only standard-compliant cabling to connect
Cisco prestandard IP Phones and wireless access
points or IEEE 802.3af-compliant devices to PoE+
ports. You must remove from the network any
cable or device that causes a PoE+ fault.

Uplink Port LEDs
The uplink ports have various status LEDs. Each port LED is labeled according to its module status.
• For SFP ports, a G labeling nomenclature is used, where G = 1 Gigabit. The The G label appears to the
left of the uplink port LED.
• For SFP+ ports, a 10G labeling nomenclature is used, where 10G = 10 Gigabit. The 10G label appears
to the left of the uplink port LED. SFP+ module ports support both SFP+ and SFP modules
• For SFP28 ports, a 25G labeling nomenclature is used, where 25G = 25 Gigabit. The The G label appears
to the left of the uplink port LED.
• For QSFP+ ports, a 40G labeling nomenclature is used, where 40G = 40 Gigabit. The The G label appears
to the left of the uplink port LED.
