Installing and Removing a Power Supply Unit

Your server contains one or two power supplies.
The second power supply is optional and provides a redundant configuration that
ensures continued operation of the system in the unlikely event one of the power
supplies fails.

Installation

Take the following steps to install a power supply unit:
1. See "Preparing Your System for Upgrade" on page 137
Be sure to turn off the power. Failure to do so causes the server
to malfunction or fail.
2. Pull the cable arm toward the rear of the server, and check the slot for installing
an optional power supply unit.
3. Hold and pull the lever of the blank cover and remove the blank cover.
