Removing Cisco 7513, Cisco 7513-MX, and Cisco 7576 Power Supplies

This section describes the procedure for removing a power supply from the Cisco 7513, Cisco 7513-MX, and Cisco 7576.

Note The procedure for installing power supplies in the Cisco 7513, Cisco 7513-MX, and Cisco 7576 is described in the “Installing Cisco 7513, Cisco 7513-MX, and Cisco 7576 Power Supplies” section on page 3-27.

Redundant power supplies support online insertion and removal (OIR); if you remove one power supply, the second supply immediately ramps up to supply full power to the system to maintain uninterrupted operation.

If you have only one power supply in your Cisco 7513, Cisco 7513-MX, or Cisco 7576, you must turn off power before removing and replacing it. Always install a filler plate over an empty power supply bay to protect the connectors from contamination.

Warning When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and the conductor.

Warning Before performing any of the following procedures, 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.

Use the following procedure to remove a power supply:

Step 1 If you have two power supplies installed and one power supply has failed, turn off (O) the system power switch on the power supply you will remove.

Step 2 AC-input power supply: Using a screwdriver, loosen the cable-retention clip on the power cable and unplug the power cable from the AC receptacle.

DC-input power supply: Disconnect the power cable leads from a DC-input power supply. (See the “Connecting Power to Cisco 7513, Cisco 7513-MX, and Cisco 7576 DC-Input Power Supplies” section on page 3-29.) Then, with the power cable leads disconnected, proceed to Step 3.
