Removing/replacing
power supply
Step 1 Hold the power supply as shown in C, 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.
Step 2 Use a Number 2 Phillips screwdriver to
replace the two M4 x 10-mm Phillips
panhead screws to secure the two power
supply ears to the chassis frame.
Step 3 Reattach the power harness plug to the
backplane receptacle. Ensure that the plug
is fully seated in the receptacle.
Step 4 Replace the power harness cover.
Step 5 Replace the fan tray.
Step 6 Replace the cover panel.
Step 7 For AC-input power supplies: On the
interface processor side of the power
supply, replace the cable retention clip on
the AC input port by pinching the sides of
the retention clip together and letting the
ends of the retention clip snap outward
into the holes in the jackscrews.
For DC-input power supplies: To provide
strain relief for the DC-input cable,
replace the nylon cable tie with a new
nylon cable tie.
