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:

1Loosen 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.

2Push the new power supply module into the server, with the retaining clip on the top, until it clicks into place.

3Connect the AC power cord for the new power supply module.

Replacing the power distribution board

To replace the power distribution board:

1Follow the instructions in “Preventing static electricity discharge” on page 24. Make sure that you turn off the server, then unplug the power cord(s) and all other cables connected to the server.

2Follow the instructions in “Opening the server case” on page 25.

3Remove the power supply modules by following the instructions in “Replacing a power supply module and power board” on page 42.

4Set the case on its side to make it easier to work on.

5Disconnect the main power, CPU power, backplane power, I2C power, and midplane power cables. See “System board” on page 5 for the location of the connectors on the system board.
