5 Push the new power supply module into the server, with the retaining clip

6 Reconnect the AC power cord for the new power supply module.
Adding an additional power supply module
Important
The dummy power supply can be
removed and the additional power
supply installed with the server turned
on.
Because only one power supply (which can support the whole server) is
normally shipped with the server, if you want to add a second power supply
module, the dummy power supply must be removed to make room for it.
To add an additional power supply module:
1 Loosen the thumbscrew (1) holding the dummy power supply in the
chassis, then use the finger recesses to pull the dummy power supply (2)
out of the chassis.
Caution
If you remove either of the power supplies
for any reason, you must install a dummy
power supply to ensure proper airflow
and cooling.
2 Push the new power supply module into the server, with the retaining clip
on the top, until it clicks into place.
3 Connect the AC power cord for the new power supply module.

To replace the power distribution board:
1 Follow the instructions in “Preventing static electricity discharge” on
page 28 . Make sure that you turn off the server, then unplug the power
cord(s) and all other cables connected to the server.
2 Follow the instructions in “Opening the server case” on page 29 .
3 Remove the power supply modules by following the instructions in
“Replacing a power supply module and power board” on page 48 .
