Removing and Installing a DC Power Supply | Cisco Systems CISCO7201

Chapter 4 Replacing Cisco 7201 Field-Replaceable Units

Removing and Installing a DC Power Supply

Step 5 Slide the wire cable-retention clip to the right, over the power supply cable.

Step 6 Plug the power supply cable into the power source.

Step 7 On the front of the router, place the power switch in the on (O) position to turn on the router.

You are finished replacing the AC power supply.

Removing and Installing a DC Power Supply

For DC power supply specifications and product numbers, see Appendix A, “Specifications”.

This section provides information about removing and replacing a DC power supply. Because of the power supply redundancy, there is no need to power off the Cisco 7201 router before removing one of the DC power supplies.

The Cisco 7201 has two of the same type of power supplies in power supply slot 1 and power supply slot 2. (See Figure 4-5.) The power supply slot numbers are on the chassis to the left of the left power supply, and to the right of the right power supply.
