To install a hot-swap power supply:
1. Remove the filler panel from the empty power supply bay by inserting your
finger into the depression on the filler panel and pulling it away from the server.
Save the filler panel in case you remove the power supply at a later time.
Note: During normal operation, each power-supply bay must have either a
power supply or filler panel installed for proper cooling.
2. Install the power supply in the bay:
a. Place the handle on the power supply in the open position (that is,
perpendicular to the power supply) and slide the power supply into the
chassis.
b. Gently close the handle to seat the power supply in the bay.
3. Plug the power cord for the added power supply into the power cord connector.
4. Route the power cord through the cable-restraint bracket.
5. Plug the power cord into a properly grounded electrical outlet.
6. Verify that the DC Power light and AC Power light on the power supply are lit,
indicating that the power supply is operating correctly.
7. If you have other options to install or remove, do so now; otherwise, go
to"Installing the cover" on page 49.

Removing a power supply

If you have installed the power supply backplane option and have installed
additional power supplies, you normally have power redundancy and hot-
swappability. However, if the load on your server requires the capacity of all installed
power supplies, you do not have redundancy or hot-swappability and must turn off
the server before removing any of your power supplies.
Attention: If you remove a power supply while the system is running, when you do
not have power redundancy, your system will abruptly cease to function.
To remove a power supply:
1. Check the LEDs on the diagnostics panel on the system board.
