Chapter 4 Removal and Replacement Procedures

Removing and Installing the AC-Input Power Supplies

Removing a 950 W or 1400 W AC-Input Power Supply

Warning

Hazardous voltage or energy is present on the backplane when the system is operating. Use
caution when servicing. Statement 1034

Note

In systems with redundant power supplies, you can replace the faulty supply while the system is
operating.

Note

This procedure covers the removal of the power supply only. For information on removing the power
entry module (PEM), see the

“Removing and Installing the Power Entry Modules (PEMs)” section

on page 4-51

Follow these steps to remove a power supply:

Step 1

Turn the power switch to the Off (0) position on the PEM for the power supply that you are removing.
(

Figure 4-1

shows the location of the AC-input PEMs on the Catalyst 6503 and Catalyst 6503-E switch

chassis.)

Step 2

Disconnect the power cord from the power source. Do not touch the metal prongs on the power cord
when it is still connected to the PEM.

Step 3

Remove the power cord from the power connection on the PEM. Do not touch the metal prongs
embedded in the PEM.

Step 4

Loosen the captive installation screws on the power supply. (See

Figure 4-2

for the Catalyst 6503

and 6503-E switches.)

Step 5

Grasp the power supply handle with one hand, and slide the power supply part of the way out of the
chassis. Place your other hand underneath the power supply, as shown in

Figure 4-3

, and slide the power

supply completely out of the chassis.

Step 6

If the power supply bay is to remain empty, install a blank power supply filler plate (Cisco
part number 800-16727-01 for the Catalyst 6503 and Catalyst 6503-E switches) over the opening, and
secure it with the captive installation screws.
