14 600W AC-Input Power Supply and Fan Tray Replacement Instructions
On the interface processor end of the power supply, remove the cable retention clip from
the AC receptacle (or tape it up out of the way); it can catch on the floor of the chassis
during the installation. To remove the clip, pinch the sides together until they clear the
jackscrews. (See Figure 3.)
Hold the supply as shown in Figure 9c and slide it into the bottom of the chassis. Use the
handles to push the supply all the way into the chassis until the ears on both sides are flush
against the chassis frame.
Use a number 2 Phillips screwdriver to replace the two M4 Phillips panhead screws to
secure the two power supply ears to the chassis frame.
Reconnect the power harness plug to the backplane receptacle. (See Figure 9a.) The
harness plug and backplane receptacle are polarized with notches at the top of both guide
tabs (top and bottom) on the plug. Ensure that the plug is fully seated in the receptacle.
To replace the power harness cover, hold the cover with one hand, with the tab on the
bottom and the open side facing away from you. Tilt the top of the panel back slightly
(toward you) and insert the tab on the bottom of the cover into the slot in the chassis floor.
(See Figure 8.)
While pushing the cover downward slightly to keep the bottom tab in the slot, push the top
of the cover back over the harness wires until the sides are flush against the backplane
cover. Ensure that all of the harness wires are under the cover.
Insert the M3 screw through the top of the harness cover and use a number 1 Phillips
screwdriver to tighten it.
Follow Steps 3 through 6 in the section "Removing and Replacing the Chassis Cover
Panel" on page 9 to replace the chassis cover panel.
Ensure that the power switch on the interface processor end of the power supply is in the
off (O) position, then reconnect the power cable to the AC receptacle (if disconnected).
Replace the cable retention clip between the two jackscrews on the power receptacle at the
interface processor end. Squeeze the sides of the clip together, insert the ends between the
jackscrews, then release the clip and guide the ends into the holes in the jackscrews.
