Power Connection Guidelines for DC-Powered Routers

When the Cisco XR 12404 Router operates with a DC PDU, observe these guidelines:

•A Cisco XR 12404 Router configured with a DC PDU and DC-input PEMs has a maximum power rating of 35A per power module and requires a dedicated DC power source to support this maximum current. The facility DC source circuit breaker protection needs to comply with safety local codes and regulations. This circuit breaker protects against short-circuit and overcurrent faults in accordance with United States National Electrical Code NFPA 70 (United States), Canadian Electrical Code, part I, CSA C22.1 (Canada), and IEC 364 (other countries).

•DC power cable leads should be #6 American Wiring Gauge (AWG) high-strand-count wire.

•Provide a dedicated power source for each power entry module installed in the router.
