Installing or replacing a hot-swap redundant power supply

This topic provides instructions on how to install or replace a hot-swap redundant power supply.
On each hot-swap redundant power supply, there is a status LED near the power cord connector. When the
LED is lit in green, it indicates that the hot-swap redundant power supply is working correctly. When the LED
is lit in amber, it indicates that the hot-swap redundant power supply is likely to fail or has failed.
The hot-swap redundant power supply helps 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 module
to provide power.
CAUTION:
Hazardous moving parts. Keep fingers and other body parts away.
CAUTION:
Never remove the cover on a power supply or any part that has the following label attached.
Hazardous voltage, current, and energy levels are present inside any component that has this label
attached. There are no serviceable parts inside these components. If you suspect a problem with
one of these parts, contact a service technician.
