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
s.
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-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.
