Power Supply Loading Guidelines; Removing A Power Supply - HP Integrity rx2660 User's & Service Manual

The supported configuration of the Office Friendly server is two power supplies. You can install or
replace a hot-swappable power supply using the procedures in this section when power is on or
off.
CAUTION:
ESD safety precautions can cause damage to the server.
NOTE: A hot-swappable device does not require that you interact with the operating system
before the device is removed from, or installed into, the server.
Power to the server does not have to be off to install or replace a hot-swappable power supply as
long as there is another power supply installed in the server, and is connected to a power source.

Power Supply Loading Guidelines

The supported configuration for the Data Center server requires that at least one power supply be
installed in slot P1 or slot P2. You can install a second, optional, hot-swappable power supply to
provide 1+1 capability. The right side (viewed from the rear of the server) hot-swappable power
supply is identified as P1, and the second hot-swappable power supply to the left is P2. See
Figure 47.
The supported configuration for the Office Friendly server requires that both power supplies be
installed.
CAUTION:
supply slot must remain covered with the supplied metal filler panel. Failure to observe this caution
can result in damage due to overheating.
Install the hot-swappable power supply in the server before attaching the new power cord. Failure
to observe this precaution can result in damage to the server.
NOTE: The Office Friendly server can run on only one power supply. However, two power
supplies must be installed to meet the acoustic requirements for an Office Friendly server. Replace
a failed power supply as soon as possible.

Removing a Power Supply

To remove a power supply:
1. Move the cable management arm from the rackslide nearest the power supplies enough to
allow access to the power supplies.
2. Remove the power cord plug from the power supply receptacle.
3. Grasp the power supply handle and push the locking tab down with your thumb to release
the power supply from the socket on the power supply riser board (1).
4. Supporting the power supply with both hands, pull the power supply out of the server (2).
