Installing A Fan Module; Replacing A Power Supply Module - Cisco Nexus 9372PX Hardware Installation Manual

Installing a Fan Module

Installing a Fan Module
Before You Begin
• A fan slot must be open and ready for the new fan module to be installed.
• You must have a new fan module on hand and ready to install within one minute of removing the original
• The new fan module must have the same airflow direction as the other fan and power supply modules
Step 1 Holding the fan module by its handle, align the back of the fan module (the side with the electrical connectors) to the
open fan slot in the chassis.
Step 2 Slide the fan module into the slot until it clicks in place.
Step 3
Verify that the Status (STS) LED turns on and becomes green.

Replacing a Power Supply Module

The switch requires only one power supply for operations but a second one can be installed for redundancy.
With one power supply providing the necessary power for operations, you can replace the other power supply
during operations. If the switch has only one power supply, you can install and power up the replacement
power supply in the open power-supply slot before removing the original power supply.
You can replace a power supply with any other power supply that is supported by the same switch so long as
it provides the same direction of airflow as the fan modules installed in the switch and you have the appropriate
power source within reach of the power cable. The coloring of the latch handle on the power supply indicates
the airflow direction as explained in the following table that lists the supported power supplies for this switch.
