4.4 Installing the PSU

In this Chassis, two PSUs are installed by default and a maximum of four can be
installed.
Adding PSUs enables redundancy of the power supply. Install the PSUs in pairs and
connect power cables to all the PSUs.
This section explains points to note when expanding the PSUs, how to install/remove
and replace the PSU.
• Do not disassemble the PSU. Doing so may cause electric shock or fire.
• When installing or removing PSUs from the server, be sure to turn off the server and all the
connected devices as well as unplugging all the power cables. Failure to do so may cause
electric shock ( "3.3 Turning Off the Server" (p.24)).
If a broken PSU is replaced when the redundant power supply is installed, the PSU can be
replaced even if the power is turned on.
• When removing the PSU or dummy PSU, do not insert your hand into the PSU slot. Doing so
may cause electric shock.
Have broken PSUs replaced as soon as possible.
Up to 10 Server Blades can be installed using the two default PSUs. The number of Server Blades that
can be installed is limited by the Server Blade configuration, and the type and number of installed PSU.
To configure redundant power supply, add PSUs.
