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

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.

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.

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).
