Connecting Source Power to the Power Supplies

To connect source power to an AC-input power supply, perform the following steps:

Step 1 Verify that the rotary power switch on the power supply is in the Standby (OFF) position.

Note A power supply bay not occupied by a power supply must have a power supply blank installed for EMI compliance and to ensure proper airflow through the router.

Step 2 Locate the AC power cord shipped with your system and verify that it is the correct type for your particular site.

For this purpose, refer to the section in Chapter 2 entitled “AC-Powered Systems.”

Note If the proper power cord was not shipped with your system, contact your service representative.

Step 3 First ensure that the bail latch is pushed down; then plug the AC power cord into the AC receptacle on the power supply faceplate (see Figure 3-19).

Note If you have a redundant AC-input power supply configuration, we recommend that you connect each power supply to an independent AC power source and install an uninterruptable power source (UPS) in your site to protect your router against power failure. Each AC-input power supply operating between 200 VAC and 240 VAC requires a dedicated 20A service.

Step 4 Position the bail latch over the power cord plug by pulling the latch up and over the plug to secure the plug in the AC receptacle on the power supply faceplate (see Figure 3-19).
