NOTE: A hot-swappable device does not require interaction with the operating system before
the device is removed from or installed into the server.
The dc power to the server does not have to be off to install or replace a hot-swappable power
supply.
Power Supply Loading Guidelines
The supported configuration of the server requires a minimum of one power supply installed in slot
P0 or slot P1. You can install a second, optional hot-swappable power supply to provide 1+1
capability. The left side (viewed from the rear of the chassis) hot-swappable power supply is
identified as P0, and the second hot-swappable power supply is identified as P1 (Figure 60).
CAUTION: When a second power supply is not used, the empty power supply slot must remain
covered with the supplied metal filler panel. Failure to observe this caution can result in damage
due to overheating if the server top cover does not remain in place
CAUTION: Install the hot-swappable power supply into the server before attaching the new power
cord. Failure to observe this caution can result in damage to the server
Removing a Hot-Swappable Power Supply
To remove a hot-swappable power supply, follow these steps:
1. Move the cable management arm from the rack slide nearest the power supplies just enough
to allow access to the power supplies.
2. Remove the power cord plug from the power supply receptacle.
3. Grasp the handle and push the locking tab down with your thumb to release the power supply
from the socket on the midplane board.
4. Support the power supply with both hands, and pull the power supply out of the server
(Figure 60).
