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.
