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 necessary, remove the power cord from the white cord retainer on the power supply’s front panel.
3
Loosen the two captive screws, located at the top and bottom of the power supply’s front panel. If
necessary, use a flat-blade screwdriver to loosen the screws. Be sure that both captive screws are
completely disengaged from the threaded holes in the chassis before continuing.
4
With one hand, grasp the handle at the front of the power supply and slowly pull the power supply out
of the power supply bay.
Do not pull the power supply completely out of the bay with one hand.
5
When the power supply is pulled out far enough (about 10”), place your other hand under the power
supply casing to support its weight.
6
Continue pulling the power supply out until it is removed from the chassis.
7
If you are not replacing the power supply, be sure to install a blank cover panel over the empty power
supply bay. To install a blank cover panel, place it over the empty power supply bay and align the panel’s
two captive screws with the threaded holes in the chassis. Once the captive screws are aligned, fasten the
blank cover panel to the chassis.
Be sure not to overtighten the captive screws. If you use a screwdriver,
the torque used to tighten the screws must not exceed 2.3 inch pounds.
