Chapter 7 Installing Internal Options
7.8 Installing a Power Supply Unit
One power supply unit is installed in this server by default. Up to two units can be
installed.
When the server has two power supply units, the redundant power supply function is
enabled.
This section provides notes on adding a power supply unit and explains how to
install, remove, and replace it.
Replace the failed power unit as soon as possible.
7.8.1 Where to Install the Power Supply Unit
Install the power supply unit in power supply unit slot 1.
• Before installation or removal, turn off the server and all peripheral devices.
Also unplug all power cables from the server ("1.4.3 Turning Off the Server"
(pg.32)). Failure to do so may cause electric shock.
However, if the redundant power supply function is supported, you can replace
a failed power supply unit as the power remains turned on.
• When removing the power supply unit, do not insert your hand into the power
supply unit slot. Doing so may cause electric shock.
• The power supply unit is heavy. Handle it with care.
If it falls, it may cause injury.
