l Have the replacement power supply unit on hand before removing an existing power supply. With a running system, swap the old and new power supply within five minutes to ensure proper air flow and to avoid overheating the system. l Only trained and qualified personnel should install or replace this equipment. l Always replace a failed power supply as soon as possible. CAUTION Whenever servicing parts in a running system, move slowly while removing, inserting, or latching the new parts. This avoids creating strong vibrations in the chassis, which might interfere with other running parts. Procedure 1. Unlatch the bale securing the power supply power cord. 2. Disconnect the power cord from the power supply. 3. Press the orange unlocking tab to unlock the power supply unit (1). Field Replaceable Units Remove a Power Supply 29 Page 34 of 80

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
