Do not use the captive installation screw or the power retainer to pull out the power supply.
Caution
Step 4
Grasp the AC power supply metal tab with one hand, and slide it part of the way out of the chassis. Place your other
hand underneath the power supply, and slide it completely out of the chassis. See figure Installing the AC Power Supply.
Step 5
Replace the AC power supply within 5 minutes. See figure Installing the AC Power Supply. If the power supply bay is
to remain empty, install a blank filler plate (Cisco part number 800-39165-01) over the opening, and secure it with captive
installation screws.
