Installing the 670-Watt hot-swap power-supply option
The server comes with a power supply in the power supply 1 (PS1) position and a
filler panel in the power supply 2 (PS2) position. You can install a 670-Watt
hot-swap power-supply option, which includes a hot-swap power supply and two
hot-swap fans.

Before you continue, review the following information:
v During normal nonredundant operation, a power supply must be installed in the
power supply 1 position and a filler panel in the power supply 2 position.
v
During normal redundant operation, a second hot-swap power supply and the
two rear hot-swap fans must be installed in the server.
Attention: To help ensure proper cooling, if a fan fails, replace it within 48
hours.
v
When the 670-Watt hot-swap power supply option is installed in the server, the
addition of the two fans enables the redundant cooling feature. If any of the fans
fail the other fans will speed up when needed to help keep the server cool and
working properly.
v
Two cable-restraint brackets are on the rear of the server. After you install the
670-Watt hot-swap power-supply option and connect the cables to the selected
devices, you can use these cable-restraint brackets to manage the cable routing.
Route the power cords through the power-cord restraint bracket. Route the
remaining cables (for example, the cables that are connected to the I/O
connectors) through the I/O cable-restraint bracket.
