Fan Tray Assembly

Fan Tray Assembly Overview

A Cisco Catalyst 9400 Series fan tray assembly—

• Is composed of a fan tray and an adapter that is attached to the fan tray. It is responsible for cooling the
entire chassis and interfacing with environmental monitors to trigger alarms when conditions exceed
thresholds.

The chassis has a built-in, front-facing, passive RFID
tag that uses Ultra High Frequency (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).

• Has side-to-side airflow for balanced airflow across the inserted cards. When facing the front of the
chassis, airflow direction is right to left.

• Can be installed and removed from the front and the rear.

• Has a built-in, front-facing, passive RFID tag that uses Ultra High Frequency (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.

• Is chassis-specific. (Add = to the model number for spares)

• Model number C9404-FAN for the Catalyst 9404R Switch.

This model has eight individual fans (two rows of four each). It supports a minimum airflow of 640
cubic feet per minute (CFM) at 100 percent fan throttle.

• Model number C9407-FAN for the Catalyst 9407R Switch.

This model has 12 individual fans (three rows). It supports a minimum airflow of 960 cubic feet
per minute (CFM) at 100 percent fan throttle.

• Model number C9410-FAN for the Catalyst 9410R Switch.

This model has 16 individual fans (four rows). It supports a minimum airflow of 1190 CFM at 100

Do not operate the system if the fan tray assembly is removed or if it is not functioning properly. An
overtemperature condition can cause severe equipment damage or an unscheduled system shutdown.

Cisco Catalyst 9400 Series Switches Hardware Installation Guide

Product Overview

Depending on the ambient conditions, the system optimises the fan-speed for temperature and pressure and
maintains the minimum fan speeds and temperatures that the chassis requires. Accordingly, the fan tray's
internal controller operates in a normal mode and a Network Equipment-Building System mode (NEBS mode).

High Availability

To ensure high availability, the system is designed to respond to fan failures by either minimising impact or
by compensating and operating at a worst case scenario specification.

High Availability

• In the normal mode—the controller optimizes fan-speed for temperature and pressure.

• In the NEBS mode—the controller responds more aggressively, to maintain proper cooling for installations
with high airflow impedance. When the fan tray operates in this mode, there may be increased noise
levels due to increased fan speeds.

You can also manually set the fan tray to operate in the NEBS mode.

• If a single fan fails, the remaining fans in the row compensate with increased speed.

• If two or more fans fail, the entire fan tray operates at full speed after one minute. Further, the fan tray
must be replaced. The individual fans are not field replaceable, you must replace the fan tray.

• If the temperature sensor fails or communication with the temperature sensor fails, the worst case operating
temperature is assumed.

• If the pressure sensor fails or communication with the pressure sensor fails, the worst case operating
pressure is assumed.

Thresholds, Alarms, and Abnormal Acoustic Conditions

Under normal operating conditions, when none of the temperature alarms have been triggered, hardware
controls fan speed. If any of the system temperature alarms are triggered, software takes fan speed control
from hardware. Refer to the System Management section of the software configuration guide for more
information.

When the fan tray operates at full speed, increased noise levels may be expected. The fan tray may operate
at full speed in these circumstances:

• If the fan tray is not installed correctly

• When operating in the NEBS mode

• If two or more fans have failed

• If the STATUS LED remains red for more than one minute

• If there is a hardware failure

• If the software watchdog timer is triggered

Power Supply Modes

Backplane

(Standby Output)

Power Supply Modes

Cisco Catalyst 9400 Series Switches offer redundant and combined configuration modes for power supplies.

The number of power supply modules installed and the system load determine the power-level that the system
expects to draw from each power supply module and consequently, the power supply mode that will be suitable.
For system power budgeting estimates and to determine power supply requirements for a specific Power over
Ethernet (PoE) configuration, use the Cisco Power Calculator.

To configure a power supply mode, enter the power redundancy-mode command in global configuration
mode. If you do not configure a mode, the default mode applies.

Warning

Combined Mode

This is the default power supply mode.

The system operates on one to eight power supply modules. The power available to the system is the sum of
power outputs of all the power supply modules in the chassis. All available power supply modules are active
and sharing power, and can operate at up to 100 percent capacity.

In case of failure in the combined mode, each operational power supply increases its output. If the output
power does not meet system requirements and the power supply autolc shutdown command is disabled,
then all the operational power supply modules may be overloaded and go into overcurrent shutdown. All
system power is then lost.

Redundant Mode

In a redundant configuration, a given power supply module can either be active, or in standby mode and switch
to active when required.

• An active power supply module is powered on, and provides output power. All active modules in a
chassis always attempt to share the load.

• A standby power supply module is powered on, but asleep. When in this mode, the power supply module’s
OUTPUT LED is blinking green.

To ensure high availability, the system is designed to respond to failures as follows:

• If all available power supply modules are active, operational power supplies continue to share current
equally. Note that the load on the available power supplies will have increased.

• If standby power supply modules are available, the minimum number of power supply modules needed
to power the load, switch to active.

You can configure an n+1 or an n+n redundant mode.

Product Overview

Installation Considerations - Power Supply Modules of Different Capacities

N+1 Redundant Mode

N is the number of active power supply modules and can be one to seven power supply modules. +1 is the
power supply module reserved for redundancy and must be configured as the standby module (power
redundancy-mode command).

The default standby power supply slot on a seven-slot or a ten-slot chassis is 8. The default standby power
supply slot on a four-slot chassis is 4. To designate a different slot as standby, enter the power

redundancy-mode command.

N+N Redundant Mode

N number of power supplies are active, and n number of power supply modules are configured as standby
(power redundancy-mode command).

For detailed software configuration information, see the System Management → Environmental Monitoring
and Power Management section of the software configuration guide for the required release.

Installation Considerations - Power Supply Modules of Different Capacities

You can install power supplies of different capacities in a Cisco Catalyst 9400 Series chassis.

If you do, and you use the default power supply mode, which the combined mode, there are no additional
factors to consider. However, in the redundant mode (n+1 and n+n), you must observe the guidelines outlined
here.

Note

While the installation of power supplies of different capacities in the same chassis is supported, it is not an
optimal use of total system power in a redundant mode.

N+1 Redundant Mode with Power Supplies of Different Capacities

The power supply module with the highest wattage or capacity must be configured as the standby.

N+N Redundant Mode with Power Supplies of Different Capacities

At the time of switch over to standby power, the total standby output power must be greater than or equal to
the total active output power at the time of a switch over (total standby output power >= total active output
power).

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.

• 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.

Cisco Catalyst 9400 Series Switches Hardware Installation Guide

Preparing for Installation

Temperature

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 system is operating in an environment that is—

• 27 to 109 °F ( -5 to +45 °C) up to 6000 feet (1800m)

• 27 to 104 °F (-5 to +40 °C) up to 10000 feet (3000m)

• 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 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.

• Do not operate the system if the fan assembly is removed or if it is not functioning properly. An
overtemperature condition can cause severe equipment damage or an unscheduled system shutdown.

Air Flow

• 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.

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
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.

Air Flow

Preparing for Installation

Power supply air intake3Chassis air intake1

Power supply air exhaust4Chassis air exhaust2

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 there is a minimum of 6 inches (15 cm) of clearance between the sides, front, and back of
any enclosure, and both the chassis air intake grill and the chassis air exhaust grill along with the power
supply unit intakes and exhausts. The upright columns of a relay rack may be located less than the
recommended side spacing provided there are substantial cutouts, holes, or vents in the structure to allow
adequate air flow through the chassis.

• 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).

Cisco Catalyst 9400 Series Switches Hardware Installation Guide

28

Preparing for Installation

Humidity

• 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.

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

Cisco Catalyst 9400 Series Switches Hardware Installation Guide

29

Corrosion

Corrosion

Corrosion of system connectors is a gradual process that may eventually lead to intermittent failures of electrical
circuits. The oil from a person’s fingers or prolonged exposure to high temperature or humidity may corrode
the gold-plated edge connectors and pin connectors on various components in the system. To prevent corrosion,
avoid touching contacts on boards and cards, and protect the system from extreme temperatures and moist,
salty environments.

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 EMI
and RFI emitted by computing equipment. Each system meets these FCC regulations. To reduce the possibility
of EMI and RFI, follow these guidelines:

Preparing for Installation

• 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.

Note

To predict and provide a remedy for strong EMI, consult experts in RFI.

If you use twisted-pair cable in your plant wiring with a good distribution of grounding conductors, the plant
wiring is unlikely to emit radio interference. If you exceed the recommended distances, use a high-quality
twisted-pair cable with one ground conductor for each data signal when applicable.

30

Caution

Category 5e, Category 6, and Category 6a cables can store large levels of static electricity because of the
dielectric properties of the materials used in their construction. Always ground the cables (especially in new
cable runs) to a suitable and safe earth ground before connecting them to the module.

Cisco Catalyst 9400 Series Switches Hardware Installation Guide

Preparing for Installation

If the wires exceed the recommended distances, or if wires pass between buildings, give special consideration
to the effect of a lightning strike in your vicinity. The electromagnetic pulse caused by lightning or other
high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic
devices. 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 switch has been shock- and vibration-tested for operating ranges, handling, and earthquake standards to
NEBS (Zone 4 per GR-63-Core). These tests have been conducted in earthquake environment and criteria,
office vibration and criteria, transportation vibration and criteria, and packaged equipment shock.

Power Source Interruptions

Systems are especially sensitive to variations in voltage supplied by the AC power source. Overvoltage,
undervoltage, and transients (or spikes) can erase data from memory or even cause components to fail. To
protect against these types of problems, power cables should always be properly grounded. Also, place the
system on a dedicated power circuit (rather than sharing a circuit with other heavy electrical equipment). In
general, do not allow the system to share a circuit with any of the following:

Shock and Vibration

• Copy machines

• Air conditioners

• Vacuum cleaners

• Space heaters

• Power tools

• Teletype machines

• Laser printers

• Facsimile machines

• Any other motorized equipment

Besides these appliances, 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 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; all other appliances left on in the area may create large
voltage spikes that may damage the system.

System Grounding

You must install a system ground as part of the chassis installation process. Chassis installations that rely only
on the AC third-prong ground are insufficient to adequately ground the systems.

Proper grounding practices ensure that the buildings and the installed equipment within them have
low-impedance connections and low-voltage differentials between chassis. When you install a system ground,

Cisco Catalyst 9400 Series Switches Hardware Installation Guide

31

System Grounding

Preparing for Installation

you reduce or prevent shock hazards, chances of equipment damage due to transients, and the potential for
data corruption.

Without proper and complete system grounding, you run the risk of increased component damage due to ESD.
Additionally, you have a greatly increased chance of data corruption, system lockup, and frequent system
reboot situations by not using a system ground.

Caution

Installations that rely solely on system grounding that uses only an AC third-prong ground run a substantially
greater risk of equipment problems and data corruption than those installations that use both the AC third-prong
ground and a properly installed system ground.

The following table lists some general grounding practice guidelines.

requirements or local laws and regulations. A 6 AWG grounding wire is preferred from the chassis to the rack
ground or directly to the common bonding network (CBN). The equipment rack should also be connected to
the CBN with a 6 AWG grounding wire.

Note

Always ensure that all of the modules are completely installed and that the captive installation screws are
fully tightened. In addition, ensure that all the I/O cables and power cords are properly seated. These practices
are normal installation practices and must be followed in all installations.

Caution

Category 5e, Category 6, and Category 6a cables can store large levels of static electricity because of the
dielectric properties of the materials used in their construction. Always ground the cables (especially in new
cable runs) to a suitable and safe earth ground before connecting them to the module.

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.

• 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.

Cisco Catalyst 9400 Series Switches Hardware Installation Guide

33

Preventing Electrostatic Discharge Damage

• If possible, send another person to get medical aid. Otherwise, assess the condition of the victim
and then call for help.

• Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate
action.

• Use the product within its marked electrical ratings and product usage instructions.

• Install the product in compliance with local and national electrical codes.

• 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.

Preparing for Installation

• 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 the Cisco
Technical Assistance Center or a local electrician.

• Use approved power cables only. You have been provided with one or more power cables with your
chassis power supply that are intended for use in your country, based on the shipping location. Should
you need to purchase additional power cables, ensure that they are rated for the product and for the
voltage and current marked on the product’s electrical ratings label. The voltage and current rating of
the power cable should be greater than the ratings marked on the label.

• 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 Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage may occur when modules or other FRUs are improperly handled, and
result 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.

Cisco Catalyst 9400 Series Switches Hardware Installation Guide

34

Preparing for Installation

• When installing a component, use any available ejector levers or captive installation screws 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 any available ejector levers or captive installation screws 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.

Power Requirements

Power Requirements

Power supplies installed on the switch chassis must be AC input only. When preparing your site for switch
installation, adhere to these requirements:

• In systems configured with more than one power supply, connect each of the power supplies to a separate
input power source. If you fail to do this, your system might be susceptible to total power failure due to
a fault in the external wiring or a tripped circuit breaker

• To prevent loss of input power, be sure that the total maximum load on each source circuit is within the
current ratings of the wiring and breakers.

• In some systems, you may decide to use an uninterrupted power supply (UPS) to protect against power
failures at your site. Be aware when selecting a UPS that some UPS models that use ferroresonant
technology may become unstable when operating with the switch power supplies that use power factor
correction. This may cause the output voltage waveform to the switch to become distorted, resulting in
an undervoltage situation in the system.

• The AC-input power supply has a detachable power cord.

• Each chassis power supply should have a separate, dedicated branch circuit.

• North America

• C9400-PWR-3200AC only—Power supplies require a 20 A circuit.

• C9400-PWR-2100AC only—Power supplies require a 15 A circuit.

• International—Circuits should be sized according to local and national codes.

• If you are using a 208 or 230 VAC power source in North America, the circuit must be protected by a
two-pole circuit breaker.

• The source AC outlet must be within 9.84 to 14 feet (3.0 to 4.293 meters) of the system, depending on
the length of the power cord, and should be easily accessible.

Cisco Catalyst 9400 Series Switches Hardware Installation Guide

35

Cabling Requirements

• The AC power receptacles used to plug in the chassis must be the grounding type. The grounding
conductors that connect to the receptacles should connect to protective earth ground at the service
equipment level.

Cabling Requirements

When running power and data cables together in overhead cable trays or subfloor cable trays, be aware of the
following caution:

Preparing for Installation

Caution

Caution

We strongly recommend that power cabling runs and other potential noise sources be located as far away as
practical from LAN cabling that terminates on Cisco equipment. In situations where this type of long parallel
cable runs exist and cannot be separated by at least 3.3 feet (1 meter), we recommend that you shield these
potential noise sources. To avoid interference, the source should be shielded by housing it in a grounded
metallic conduit.

Also be aware of the following caution concerning the use of Category 5e and Category 6 Ethernet cables:

Category 5e, Category 6, and Category 6a cables can store large levels of static electricity because of the
dielectric properties of the materials used in their construction. Always ground the cables (especially in new
cable runs) to a suitable and safe earth ground before connecting them to the module.

Rack-Mounting Guidelines

Rack Specifications

Cisco Catalyst 9400 Series Switches are designed to be installed in standard, 19-inch equipment racks that
meet EIA-310-D specifications. Before rack-mounting the chassis, ensure that the equipment rack complies
with all requirements and guidelines

Mounting Location Guidelines

Cisco Catalyst 9400 Series Switches must be front-mounted.

Accordingly, you can install the chassis in 2-post or 4-post racks, but in a 4-post rack, the rear posts are not
used for mounting.

Width and Depth Requirements

Use a tape measure to verify the interior dimensions of the rack

• Measure the space between the inner edges of the left front and right front mounting posts. The chassis
is 17.30 inches (43.942 cm) wide and must fit between the mounting posts.

• Measure the depth of the rack from the outside of the front mounting posts to the outside of the rear
mounting strip. The chassis is 16.30 inches (41.40 cm) deep.

Rack-Mounting Guidelines

Height Requirements

The rack must have sufficient clearance in terms of height, to insert the chassis. Chassis height is also measured
in rack units (RU or just U) where 1 RU or 1 U equals 1.75 inches (44.45 mm). A typical server rack is 42
RU or 42 U in height.

The chassis heights are as follows:

• The Catalyst 9404R Switch chassis height—10.5 inches (26.67 cms)—6 RU.

• The Catalyst 9407R Switch chassis height—17.41 inches (44.22 cms)—10 RU.

• The Catalyst 9410R Switch chassis height—22.61 inches (57.43 cms)—13 RU.

Warning

Warning

If the equipment rack is on wheels, ensure that the brakes are engaged and that the rack is stabilized.

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. Statement 1006

Take care when connecting units to the supply circuit so that wiring is not overloaded. Statement 1018

To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended
ambient temperature of: 104o F (40o C) Statement 1047

Note

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
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.

After you install the system ground lug, follow these steps to correctly attach the ESD wrist strap:

Procedure

Step 1 Attach the ESD wrist strap to bare skin as follows:

a) If you are using the ESD wrist strap supplied with the FRUs, open the wrist strap package and unwrap

the ESD wrist strap. Place the black conductive loop over your wrist and tighten the strap such that it
touches your bare skin well.

b) If you are using an ESD wrist strap equipped with an alligator clip, open the package and remove the ESD

wrist strap. Locate the end of the wrist strap that attaches to your body and secure it to your bare skin.

(unpainted surface) on the rack. We recommend that you touch the clip to an unpainted rack rail so that any
built-up static charge is then safely dissipated to the entire rack.

a) If you are using the ESD wrist strap that is supplied with the FRUs, squeeze the spring clip jaws open,

position the spring clip to one side of the system ground lug screw head, and slide the spring clip over
the lug screw head so that the spring clip jaws close behind the lug screw head.

Note

b) If you are using an ESD wrist strap that is equipped with an alligator clip, attach the alligator clip directly

over the head of the system ground lug screw or to the system ground lug barrel.

When handling modules, follow these guidelines:

• Handle carriers using the available handles or edges only; avoid touching the printed circuit boards or
connectors.

• Place a removed component boardside 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.

• Never attempt to remove the printed circuit board from the metal carrier.

Caution

The spring clip jaws do not open wide enough to fit directly over the head of the lug screw or
the lug barrel.

For safety, periodically check the resistance value of the antistatic strap. The measurement
should be between 1 and 10 megohm (Mohm).

Verifying the Switch Chassis Installation

To verify the switch chassis installation, perform these steps:

Procedure

Step 1 Verify that the ejector levers of each module are fully closed (parallel to the faceplate) to ensure that the

supervisor engine and all the switching modules are fully seated in the backplane connectors.

Step 2 Check the captive installation screws of each module, and tighten any loose captive installation screws.

Step 3 Verify that all empty module slots and power supply bays have blanks installed properly. The blanks optimize

the air flow through the chassis and contain EMI.

Warning

Step 4 Turn on the power supply switches to power up the system. During the power-up sequence, the system performs

a series of bootup diagnostic tests.

Blank faceplates and cover panels serve three important functions— They prevent exposure to
hazardous voltages and currents inside the chassis; they contain EMI that might disrupt other
equipment; and they direct the flow of cooling air through the chassis. Do not operate the system
until all cards, face plates, front covers, and rear covers are in place. Statement 1029

Cisco Catalyst 9400 Series Switches Hardware Installation Guide

77

Verifying the Switch Chassis Installation

What to do next

Additional system diagnostic tests are available. These tests allow you to perform a complete sanity check on
the system prior to inserting the system into your network and to monitor the health of the system while the
system is running.

Tip

When prestaging systems in a nonproduction environment, we recommend that you run all the diagnostic
tests, including the disruptive tests, to prescreen the systems for failures, if any.

The system can safely run without a fan tray only for a few minutes, until critical temperature threshold is
exceeded. Watch for any alarms triggered in software. After the critical temperature threshold is exceeded
without sufficient cooling, the system shuts down if the alarm is not cleared.

When the fan tray is removed and replaced in a non operating system, there is no time constraint.

Following the Correct Removal and Replacement Procedure

When you order the fan tray or a spare, the entire fan tray assembly is shipped. The fan tray assembly consists
of the fan tray and an adapter that is attached to the fan tray.

You can remove and replace the fan tray from the front or the rear. When removed from the front of the
chassis, only the fan tray is removed. When removed from the rear, the entire fan tray assembly (including
the adapter) is removed. Accordingly, you must detach the adapter from the spare fan tray assembly when
installing or replacing the fan tray from the front; you must install the entire fan tray assembly when installing
the spare from the rear.

Removal and replacement from the front is suited to situations where access to the rear of the system is
restricted. For instance, where the installation is in a closet.

Removal and replacement from the rear is suited to situations where input and output cables are routed across
the front panel, limiting access to the front panel of the fan tray.

Follow the corresponding removal and replacement procedures.

Enabling the Service Mode Before Removing the Fan Tray

Enabling the Service Mode Before Removing the Fan Tray

This procedure describes how you can enable the service mode by using Cisco IOS commands before you
remove the fan tray from the chassis. Enabling the service mode pushes the fans to operate at full speed and
cool the system down sufficiently, allowing the system to sustain temperatures for the duration of servicing.

In a system that is operational, this applies to removal or replacement procedures from the front and the rear.
You do not have to enable this mode if you are removing and replacing the fan tray in a system that is not
powered on.

Starting in the privileged EXEC mode, enter the following commands:

Removing and Replacing FRUs

Before you begin

To check the operation of the fans, you should have powered up the chassis.

Procedure

Step 1 Listen for the fans; you should immediately hear them operating. If you do not hear them, ensure

a) That the fan tray is inserted completely in the chassis
b) That the faceplate is flush with the chassis panel.
c) That the captive installation screws have been tightened sufficiently.

Removing and Installing the Power Supply

Important

Step 2 Check if the fan tray LED is lit and is green.

Step 3 If after several attempts the fans do not operate, or if you experience trouble with the installation (for instance,

if the captive installation screws do not align with the chassis holes), contact the Cisco TAC for assistance.

If the fan tray is not installed correctly, the fans may not run at all, or they may run at full speed.
When the fan tray operates at full speed, increased noise levels may be expected.

Removing and Installing the Power Supply

Cisco Catalyst 9400 Series chassis support one to eight field-replaceable, AC-input power supply modules,
each with its own on/ off rocker switch.

This section describes how to remove and install the AC-input power supplies for the chassis.

The power supplies are hot-swappable, so in redundant mode, you do not have to power down the switch to
replace or upgrade the power supplies.

Installing the Power Supply

Before you begin

Ensure that you have installed the cable guide before you begin the procedure. This is to properly guide and
arrange the power cords that you will attach as part of the installation. Since there are two rows of power
supply bays, the cable guide ensures that the power cords from one row of power supplies do not interfere
with the removal or replacement of modules in another row.

Procedure

Step 1 Remove the replacement power supply from its shipping packaging.

Step 2 Verify that the replacement power supply power switch is in the off (0) position.

Step 3 If installed, remove the blank power supply cover from the empty power supply bay. For information about

removing blank covers, see Removing and Installing Power Supply Blanks, on page 96. Save the blank cover
for future use.

Step 4 Grasp the power supply handle with one hand and place your other hand underneath to support the bottom of

the power supply. Slide the power supply all the way into the power supply bay. Make sure that the power
supply is fully seated in the bay.

When correctly installed, the latch on the power supply locks-in the module, to avoid accidental removal of
the module.

Step 5 Verify that all site power and grounding requirements have been met.
