This topic provides instructions on how to replace a hot-swap redundant power supply module.
This topic applies only to server models that come with hot-swap redundant power supply module(s). For
each hot-swap redundant power supply module, there might be one or two status LEDs on the power
supply module near the power cord connector. When the green LED is lit, it indicates that the hot-swap
redundant power supply module is working properly. When the red LED is lit, it indicates that the hot-swap
redundant power supply module has failed.
The hot-swap redundant power supply modules help you avoid signicant interruption to the operation of
the system when a power supply module fails and you can replace a hot-swap redundant power supply
module without turning off the server.
Note: To maintain the EMI integrity and cooling of the server, install a new hot-swap redundant power
supply module as soon as you remove the failing one or cover the other bay with a shield if you just use
one module to provide power.

Hazardous moving parts. Keep ngers and other body parts away.
