Power Connection Guidelines for DC-Powered Routers

When the Cisco XR 12406 Router operates with a DC PDU, observe these guidelines:

•A Cisco XR 12406 Router configured with a DC PDU and DC-input PEMs require a dedicated 45A DC circuit breaker for each DC power source. 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.

•Install an uninterruptable power source where possible.
