Chapter 3 Installing the Cisco ASR 903 Router

Installing the Power Supply

Caution Secure the wires coming in from the terminal block plug so that they cannot be disturbed by casual contact.

Step 7 Ensure that the terminal block plug is fully seated in the terminal block header on the DC power supply panel. The plug has a locking feature. You should hear a snap or click when it is installed properly.

Step 8 Use a tie wrap to secure the wires to the rack, so that the wires are not pulled from the terminal block plug by casual contact. Make sure the tie wrap allows for some slack in the ground wire, as shown in Figure 3-22.

Step 9 Use a tie wrap to secure the wires to the handle. Leave a service loop on the ground wire between the handle and the connector such that it is the last to receive strain if the wires are pulled.

This completes the procedure for connecting the DC power supply in the Cisco ASR 903 Router.

If you are installing a redundant DC power supply, repeat these steps for the second power source.
