DC Power System Input for Cisco ASR 1002
The DC power supply operates within specification from –40.5VDC to –72VDC continuously once the
the power supply DC input turn on threshold of –43.5V has been reached. Table 2-20 shows the common
input ranges for reference only. The DC power input connector is a euro-style terminal block with three
wires, one positive, one negative, and one grounding wire.
DC Power System Output for Cisco ASR 1002
The DC power supply output tolerance is defined in Table 2-21 under all combinations of DC input line
variation. Total system power consumption should not exceed 470 watts or output rating of each power
supply.
Note Two power supplies are used for redundant operation. System total power consumption shall never
exceed rating of one power supply to maintain redundancy.
