Power Supplies for the Cisco ASR 1001 Router
Each Cisco ASR 1001 Router power supply provides 400 W of output power. The power supplies are used
in a 1 + 1 redundant configuration. There is no input switch on the faceplate of the power supplies. The power
supply is switched from standby to On by way of a system chassis STANDBY/ON switch. The power supply
slot numbers are on the rear of the chassis to the left side of each power supply. When facing the rear of the
chassis, power supply slot 0 (PS0) is to the left and power supply slot 1(PS1) is to the right (next to the power
supply standby switch).
The Cisco ASR 1001 Router supports the following power supplies:
• Cisco ASR 1001 Router AC power supply—Provides 400 watt output power with two DC voltage
outputs: +12 V and +5 V. The AC power supply operates between 85 and 264 VAC. The AC power
supply current shares on the 12 V output and is used in a dual hot pluggable configuration. The AC
power supply consumes a maximum of 471 W of input power.
• Cisco ASR 1001 Router DC power supply—Provides 400 watt output power with two DC voltage
outputs: +12 V and +5.0 V. The power supply operates between –40.5 and –72 VDC. The DC power
supply current shares on the 12 V output and is used in a dual hot pluggable configuration. The DC
power supply consumes a maximum of 500 W of input power.
The Cisco ASR 1001 Router can support two AC or two DC power supplies. Do not install the AC and
DC power supply units in the same chassis.
