Removing and Replacing the Power Harness Cover
Removing power harness cover
Holding the cover with one hand, tilt the top of the cover back toward you, then pull it up
slightly so that the tab clears the slot in the chassis floor.
When the tab clears the slot, pull the cover straight back off the harness and out of the
chassis.
Disconnect the power harness plug from the backplane receptacle by pulling the polarized
plug out of the receptacle; do not pull on the wires. (See Figure 9a.)
Use a number 2 Phillips screwdriver to remove the two M4 Phillips panhead screws that
secure the power supply ears (one on each side of the power supply) to the chassis frame.
(See Figure 9a.)
Using both hands, grasp both of the power supply handles and pull the power supply about
halfway out of the bay (see Figure 9b), then grab the sides of the supply and pull it out of
the chassis. (See Figure 9c.)
