HP (Hewlett-Packard) RP4410 ユーザーズマニュアル

Removing and Replacing Components

The supported configuration of the HP 9000 rp4410 or rp4440 server requires a minimum of one power 
supply. A second, optional hot-swappable power supply, can be installed to provide N+1 capability.

The left side (viewing from the rear) hot-swappable power supply is identified as P0, the second 
hot-swappable power supply is identified as P1. Each hot-swappable power supply requires a separate power 
cord be installed in the appropriate power cord receptacle and attached to a power cord support bracket.

The empty hot-swappable power supply slot P1 must remain closed with the supplied metal 
cover in place when a second power supply is not used. The server can be damaged due to 
overheating if the cover does not remain in place.

If the system is powered off, install the hot-swappable power supply into the server before 
attaching the new power cord at the rear of the system. Failure to observe this caution results 
in damage to the server.

To remove a hot-swappable power supply, follow these steps:

Step 1. If rack-mounted, slide the server out of the rack until it stops. (See “Accessing a Rack-Mounted 

Server” on page 177.)

Step 2. Remove the cable management arm from the rackslide nearest the power supplies. The cable 

management arm does not need to be completely removed but moved just enough to enable access 
to the power supplies.

Step 3. Remove the power cord plug from the power receptacle.

Step 4. Loosen the captive thumbscrew located at the top left of the power supply.
