Note: If your server comes with one hot-swap power supply installed in the power supply bay 1 (the bay
number is marked on the rear of the chassis) and you are installing a hot-swap redundant power supply
to provide redundant power, you need to remove the shield that protects the power supply bay 2 rst
and save the shield for future use. Insert a nger into the hole in the metal shield, press the tab
1 in
the direction as shown, and then pull the shield out of the chassis.

3. Connect the power cord to the power connector on the new hot-swap redundant power supply. Then,
check the status LED near the power 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. You need to reinstall or replace it.
