Hot-Swappable Power Supplies

Power Supply Load Order
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.
WARNING
Be careful when installing a hot-swappable power supply. It is heavier than it
appears.
CAUTION
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.
CAUTION
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.
Removing a Hot-Swappable Power Supply
WARNING
Be careful when removing the hot-swappable power supply. It is heavier than it
appears.
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.
