8.7 Power supply units
The server can be equipped with up to three power supply units. As a standard,
servers are delivered with one power supply unit. This power supply unit is suffi-
cient for the following server configuration:
– up to four hard disk drives with 1.6-inch hard disk subsystem
– up to six hard disk drives with 1-inch hard disk subsystem
– all controllers (restriction: up to two 3-channel or 4-channel disk array
controllers)
– 4 GB memory
– two processors
An additional power supply unit is required for servers with more than two RAID
controllers or more than four or six disk drives, depending on the configuration.
A redundant power supply can be set up with two or three power supply units.
If one unit fails, the remaining power supply units ensure unimpaired further
operation. The defective power supply unit can be replaced during operation
(hot plug power supply unit).
V
CAUTION!
Only power supply units of the same type may be mounted.
I
If you want to install, remove, or change a power supply unit on the rack
model, you must first unlock the joint of the articulated cable guide (see
section "Installing the rack model" on page 26) so that the articulated
cable guide can be folded away (figure 9 on page 31).
Once you have exchanged, installed, or removed a power supply unit,
you can fold back the articulated cable guide. The springs of the joint lock
automatically.
