Removing and Replacing a Hot-Swappable Power Supply
The server can have one or two hot-swappable power supplies. These power supplies are located
at the rear of the server. The supported configuration of the server requires a minimum of one
power supply. You can install or replace a hot-swappable power supply using the procedures
in this section when system power is on or off.
CAUTION: Observe all ESD safety precautions before removing or replacing a power supply.
Failure to follow ESD safety precautions can result in damage to the server.
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 6-6 ).
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 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 6-6 ).
