Cisco ASR 1002-X Router Overview and Installation
+24 VDC Power System Input for the Cisco ASR 1002-X Router
The +24 VDC power supply operates within specification between +21 VDC and +36 VDC continuously
after the power supply DC input is turned on. The power supply measures the input voltage at the power
supply terminals and turns off the supply when the input voltage reaches 19.0 V +/- 0.5 V when this low
voltage threshold is reached, the power supply does not resume operation until the input voltage reaches 20.0
V +/- 0.5 V. When the turn-on threshold of 20 V is reached, then the +24 VDC power supply meets all
specification requirements down to the low voltage threshold of 19 V (+/- tolerance).
+24 VDC Power System Output for the Cisco ASR 1002-X Router
The +24 VDC power supply output tolerance is defined in the following table, under all combinations of +24
VDC input line variation. The total system power consumption should not exceed 470 W or output rating of
each power supply.
Two power supplies are used for the redundant operation. The system's total power consumption should
Note
not exceed the rating of one power supply to maintain redundancy.

Any combination of output voltage and current cannot exceed the total power rating of 470 W.
The following are the important notes regarding the +24 VDC power supply in the Cisco ASR 1002-X Router:
• Output Voltage Alarm Threshold—The Output Voltage Alarm is raised when the output voltage is below
the low end of the minimum limit or above the high end of the maximum limit (as shown in the following
table). When the output voltage is above the high end of the minimum limit or below the low end of the
maximum limit, the LED does not turn to red.
