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