Chapter 2 Preparing for Installation

Safety and Compliance

•Cisco 12006 and Cisco 12406 Routers with an AC power distribution unit (PDU) and AC-input power supplies are shipped with AC power cords equipped with three-wire electrical grounding-type plugs that will fit into only a grounding-type power outlet. This is a safety feature. The equipment grounding should be in accordance with local and national electrical codes.

•Cisco 12006 and Cisco 12406 Routers with a DC PDU and DC-input power entry modules (PEMs) require an external DC circuit breaker for each DC power source:

–Original series Cisco 12006 and Cisco 12406 router input power shall not draw more than 45A max. @ 40.5VDC form each DC power source.

–Enhanced series Cisco 12006 and Cisco 12406 router input power shall not draw more than 60A max. @ 40.5VDC from each DC power source.

This circuit breaker should protect 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).

•Only a DC power source that complies with the safety extra-low voltage (SELV) requirements in UL 1950, CSA-C22.2 No. 950, EN60950, ACA TS001, AS/NZS 3260, and IEC60950 should be connected to a Cisco 12006 or Cisco 12406 Router with DC PDU and DC-input PEMs.

•Cisco 12006 or Cisco 12406 Routers configured with DC-input PEMs should be installed in a restricted access area in accordance with Articles 110-16, 110-17, and 110-18 of the National Electric Code, ANSI/NFPA 70.

•Cisco 12006 or Cisco 12406 Routers configured with a DC PDU shall have a readily accessible disconnect device incorporated in the fixed wiring.
