Each PEM weighs 10.5 pounds (4.76 kg), and can deliver up to 1400 W at
–48 VDC.
Only a DC power source that complies with the safety extra-low voltage
(SELV) requirements in UL1950, CSA 950, EN 60950, and IEC950 can be
connected to a PEM.
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).
Function
PEM is operating normally in a powered-on
condition.
DC power is present at the PEM input and
within the specified limits.
Indicates input is wired backward at the PDU
input.
