Replacing A Power Supply Module; Removing An Ac Power Supply - Cisco Nexus 9364C Hardware Installation Manual

Replacing Components
If the STS LED does not turn on, slide the module out of the chassis, and visually check the electrical connectors on
the back side of the chassis for damage. If damaged, contact Cisco Technical Assistance for help. If undamaged,
repeat the previous step to reinstall the module.

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.
If you need to change the airflow direction of the switch modules, you must shut down the switch before
Note
changing all of the modules to modules using the other airflow direction.
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. The following list describes the power
supplies supported by this switch.
• N9K-PAC-1200W-PE (1200-W, port-side exhaust (blue latch) power supply requiring an AC power
• N9K-PAC-1200W-PI (1200-W, port-side intake (burgundy latch) power supply requiring an AC power
• N9K-PUV-1200W (1200-W, dual-direction (white latch) high-voltage AC/DC power supply requiring
• NXA-PDC-930W-PE (930-W, port-side exhaust (blue latch) power supply requiring a DC power source)
• NXA-PDC-930W-PI (930-W, port-side intake (burgundy latch) power supply requiring a DC power

Removing an AC Power Supply

To remove an AC power supply, you must first disconnect the power cable and then remove the module from
the chassis.
Before You Begin
• To replace a power supply during operations, you must have a functioning power supply providing

power to the switch while you replace the other power supply. If there is only one power supply installed
in the switch and you need to replace it, install the new power supply in the open slot and power it up
before removing the original power supply.
