Remove a Power Supply

Prerequisites
NOTE:
● You can replace one power supply while the system is running. As long as one power supply is functional, you do not
have to power down the system.
● 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.
● Only trained and qualified personnel should install or replace this equipment.
● 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.

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).
4. Continuing to depress the unlocking tab and using the power supply handle, pull the unit from the chassis (2).
