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.
