Chapter 3 Installing the Router

Connecting to a DC Power Source

Step 2 Locate the two AC power cords and remove them from their shipping packaging. Verify that the AC power cords shipped with the power supplies are the correct type for your site.

Note If you have received the wrong type of AC power cord, contact your service representative for a replacement.

Step 3 Plug the socket end of each AC power cord into a receptacle on the PDU. (See Figure 3-18.)

Step 4 Insert the plug end of each AC power cord into the AC power source outlet.

For full redundancy, connect each AC-input power supply to an independent power circuit with its own circuit breaker. We also recommend that you use an uninterruptable power source (UPS) to protect against power failures at your site.

Step 5 Verify that the AC power source circuit breaker servicing each of the AC-input power supplies is switched on.

Note When operating your router on a single power module, the second power module bay must have a blank filler (MAS-GSR-PWRBLANK=) installed to ensure EMI compliance.

Connecting to a DC Power Source

This section provides the procedure for connecting the router to a DC power source.

Warning The circuit breaker switch on the faceplate of the DC-input PEM should be in the OFF position.
