Hot-Swap Power Supplies
The HP Integrity rx4640 Server has two 200-240 VAC hot-swap power supply units (PSU). These PSUs are located at the rear
of the HP server. The supported configuration of the HP Integrity rx4640 Server requires a minimum of one PSU be installed.
CAUTION
Observe all ESD safety precautions before attempting this procedure. Failure to follow ESD safety
precautions could result in damage to the server.
NOTE
A hot-swap device does not require interaction with the operating system before the device is removed from
or installed into the server.
The AC power to the server does not have to be off to remove or replace a hot-swap power supply.
Power Supply Load Order
The supported configuration of your hp Integrity rx4640 Server requires a minimum of one 200-240 VAC PSU. A second,
optional hot-swap PSU, may be installed to provide N+1 capability. Each hot-swap requires a separate power cord.
The left side (viewing from the rear) hot-swap PSU is identified as P 0, the second hot-swap power supply is identified as P 1.
Each hot-swap PSU requires a separate power cord be installed in the appropriate power cord receptacle and attached to a
power cord support bracket.
CAUTION
The empty hot-swap PSU slot P 1 must remain closed with the supplied metal cover when a second PSU is
not used. Your server may be damaged due to overheating if the cover does not remain in place.
WARNING
Be careful when installing a hot-swap power supply. It is heavier than it appears.
CAUTION
If the system is powered down, install the hot-swap PSU into the server before attaching the new power cord
at the rear of the system. Failure to observe this caution will result in damage to the server.
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 2.
Remove the power cord plug from the power receptacle.
Step 3.
Loosen the captive thumbscrew located at the top left of the PSU.
Step 4.
