Removing a Power Supply
1
Before removing a power supply, make sure that the power switch is in the off ( O ) position. Unplug
the power cord from the AC socket, as well as from the socket on the power supply’s front panel.
2
If you wish to remove the power cord proceed to Step 3; otherwise proceed to Step 5.
3
Remove the two screws on the top of retainer with a Phillips-head screwdriver. Do not discard these
screws; you will need to reinstall them later.
4
Remove the top part of the metal retainer and place it in a safe location.
5
Loosen the four captive screws, located at the four corners of the power supply’s front panel. If neces-
sary, use a flat-blade screwdriver to loosen the screws.
