Removing a Hot-Swap Power Supply

To remove a hot-swap PSU, perform the following steps:
CAUTION Be careful when removing the hot-swap power supply. It is heavier than it appears.
Step 1. If rack mounted, slide the HP Server back out of the rack until it stops. (Refer to the hp9000 rp4440
Installation Guide for additional information.)
Step 2. Remove the cable management arm from the rackslide nearest the PSUs. The cable management
arm does not have to be completely removed but moved just enough to allow access to the PSUs.
Step 3. Remove the power cord plug from the power receptacle.
Step 4. Loosen the captive thumbscrew located at the top left of the PSU.
Step 5. Grasp the handle and pull the PSU out of the server.

Replacing a Hot-Swap Power Supply

Step 1. Supporting the PSU with both hands, slide it into the empty slot until it plugs into the socket on
the internal power distribution board. Tighten the thumbscrew hand-tight.
Step 2. Install the power cord into the PSU socket.
Step 3. Apply power to the new PSU and the LED should immediately turn on.
Step 4. If rack mounted, slide the HP Server back into the rack until it stops.
