Replacing A Power Supply Module - Cisco Nexus 92348GC-X NX-OS Hardware Installation Manual

Replacing a Power Supply Module

• 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
Verify that the Status (STS) LED turns on and becomes green.
Replacing a Power Supply Module
The switch requires two power supplies for redundancy. With one power supply providing the necessary
power for operations, you can replace the other power supply during operations so long as the new power
supply has the same airflow direction as the other modules in the chassis.
You can replace a power supply with another supported power supply that has the same power source type
and the same wattage rating as the other installed power supply. Additionally, the airflow direction of the
power supply must match or conform to the airflow direction of the installed fan modules. For the airflow
direction used by the switch, see the coloring of the fan modules.
Replacing an AC Power Supply
You can replace an AC power supply during operations so long as the other power supply provides to the
switch.
Before you begin
•
• An AC power source must be within reach of the power cable that will be used with the replacement

installed in the switch.
Note
You can determine the airflow direction by looking at the coloring of the latch
on each power supply. AC power supplies with burgundy latches have port-side
intake airflow direction, and power supplies with blue latches have port-side
exhaust airflow direction.
power supply. If you are using n+n power redundancy, there must be a separate power source for each
power supply installed in the chassis.
AC power supplies connected to AC power sources are automatically grounded through their power
cable.
