Replacing a Power Supply

Caution: Removing a power supply significantly changes the airflow within

the enclosure. The system could shut down because of overheating unless the

power supply is replaced within

five minute

Note: Replacement power supply assemblies do not include a variable speed blower.

You must remove the operational blower from the defective power supply and install the

blower on the new supply.

1. Disengage the cord lock 1 and disconnect the AC power cord from the

defective supply.

2. While lifting up on the power supply port wine-colored module latch 2, grasp

the blower element 3 and pull the defective power supply out of the

enclosure.

Caution: When removing the left power supply, move the cord lock on the

right power supply out of the way to avoid dislodging the right power supply

and causing your system to become overheated.
