Removing An Ac Power Supply - Cisco Nexus 93120TX Installation Manual

Replacing Modules
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.

Removing an AC Power Supply

If you are replacing one of two power supplies in the switch chassis, you remove one power supply while the
other one provides power to the switch and install the new power supply in the open slot. If you need to replace
the power supply in a chassis that has only one power supply, install the new power supply in the open power
supply slot and power it up before removing the older power supply.
Step 1 Holding the plug for the power cable, pull the plug out from the power receptacle on the power supply and verify that
both power supply LEDs are off.
Step 2
Release the power supply from the chassis by moving the power supply release latch to the left and then pulling the
power supply part way out of the chassis.
Step 3 Place your other hand under the power supply to support it while you slide it out of the chassis.
Caution Do not touch the electrical connectors on the back side of the module and prevent anything else from coming
into contact with and damaging the connectors.
Step 4 If the power supply slot in the chassis is to remain empty, install a blank power supply filler panel (part number
N2200-P-BLNK). Otherwise, install another power supply in the slot as explained in
on page 40.
