Cisco 12006 and Cisco 12406 Router Installation and Configuration Guide
OL-11497-03
•
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.
