Note The following procedure assumes you have already removed the chassis cover panel, the fan tray, the power harness cover, and the power harness. If you have not, refer to the appropriate sections in the Cisco 7500 Series Installation and Conﬁguration Guide for instructions.

Note AC-input power supply is shown above. Step 1 Turn off the system power switch.

Warning Before working on the chassis or near power supplies, disconnect the power cable on AC units or disconnect the power at the circuit breaker on DC units.

Step 2 Disconnect the power cable from the power supply.

For the AC-input power supply: Move the cable retention clip away from the power cable and disconnect the power cable from the AC receptacle.

For the DC-input power supply: Use a wire cutter to cut the nylon cable tie that provides strain relief for the DC power cable. (You must replace this nylon cable

tie with a new one after the new power supply is installed.) Remove the DC-input cable from the terminal block.

Step 3 Attach an ESD-preventive strap between you and any unpainted chassis surface.

Step 4 Disconnect the power harness plug from the backplane receptacle by pulling the polarized plug out of the receptacle; do not pull on the wires.

Step 5 Use a Number 2 Phillips screwdriver to remove the two M4 x 10-mm Phillips panhead screws that secure the power supply ears (one on each side of the power supply) to the chassis frame.

Step 6 Using both hands, grasp both of the power supply handles and pull the power supply about halfway out of the bay. Then grasp the sides of the power supply and pull it out of the chassis.
