6.8 Installing a Power Supply Unit
One power supply unit (PSU) is installed in this server by default. Up to two PSUs
can be installed.
By installing two PSUs, the redundant power feature can be enabled.
This section contains notes on adding a PSU, and explains the procedures for
installation, removal, and replacement.
Replace the defective PSU as soon as possible.
6.8.1 Installation Location of Power Supply Unit
Install the PSU in PSU slot 2.
6.8.2 Installable Power Supply Units
The following power supply units can be installed in this server.
• Before installing/removing the PSU, turn off the server and all peripheral
devices. Also unplug all power cables from the server ("1.4.3 Turning Off the
Server" (p.32)). Failure to do so may cause electric shock.
However, when the redundant power function is supported, a defective PSU
can be replaced without shutting down the server.
• Do not insert your hands in the PSU slot when removing the PSU. Doing so
may cause electric shock.
• The PSU is heavy, so handle it carefully.
If you drop it by mistake, injuries may result.
