Installing Additional Components and Configuring

Installing Power Supplies and Disk Drives

This section provides information about installing hot-swap power supplies and hot-plug disk drives. Hot- swap power
supplies are located at the rear of the hp Integrity rx4640 Server and hot-plug disk drives are located behind the front bezel.
CAUTION A hot-plug device may require interaction with the operating system before the device can be safely installed
into the server. Verify that the operating system supports installing disk drives while the operating system is
running. If the operating system does not support this feature, shut down the operating system before
attempting this procedure. Failure to observe this caution will result in system failure.
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 install a hot-swap power supply.

Installing Hot-Swap Power Supply Units (PSU)

Power Supply Load Order
The supported configuration of an hp Integrity rx4640 Server requires a minimum of one 200-240 VAC power supply unit to
be installed. A second, optional hot-swap PSU, may be installed to provide N+1 capability.
The left side (viewing from the rear) hot-swap PSU is identified as P 0, and the second hot-swap power supply is identified as
P 1. Each hot-swap PSU requires a separate power cord, installed in the appropriate power cord receptacle.
CAUTION
The empty hot-swap PSU slot P 1 must remain closed, with the supplied metal cover, when a second power
supply is not used. Your server may be damaged due to overheating if the cover does not remain in place.
