Power Supply Replacement

Refer to the Cisco 7010 Hardware Installation and Maintenance or Cisco 7505 Hardware

mounting hardware.

Power Supply Replacement

To access the power supply, you must remove the chassis cover panel and expose the chassis interior.
Two captive slotted screws secure the cover panel to the chassis.

The power supply rests on the floor of the chassis, under the card cage and backplane. Two M4
Phillips screws secure the power supply to the interior chassis frame. The power harness cover
shields the power harness, which carries DC voltages from the power supply to a polarized
connector on the backplane. Because the power harness cover straddles both the power supply and
backplane cover, you must remove it to access the power supply. A tab at the bottom of the power
harness cover fits into a slot in the chassis floor; a single Phillips screw secures the top of the power
harness cover to the backplane cover. To remove the power supply, you need to disconnect the
DC-input power cable, remove the power harness cover, disconnect the power harness from the
backplane, and remove the two M4 Phillips screws. The noninterface processor end of the power
supply has handles for pulling the supply out of the chassis.

Removing and Replacing the Chassis Cover Panel

The two captive slotted screws are the only fasteners on the cover panel. Five shallow tabs at the
bottom edge of the panel fit into slots at the base of the chassis opening. The tabs act as a pivot point
for pulling the top of the panel away from the chassis opening, and as guides to align the panel when
replacing it.

Follow these steps to remove and replace the chassis cover panel:

Step 1

Turn OFF (O) power to the chassis, turn OFF the source power, and disconnect the power
cable at the DC power source. You can leave the ground cable connected.

Warning

Before conducting any of the following procedures, and to prevent short-circuit or shock

hazards, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate
the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the
OFF position, and tape the switch handle of the circuit breaker in the OFF position.

Step 2

On the front of the cover panel, use a 3/16-inch, flat-blade screwdriver to loosen the two
captive screws. (See Figure 3.)
