Electrical Circuit Requirements
Each Cisco 1000 Series Router requires a dedicated electrical circuit. If you equip it with dual power
feeds, provide a separate circuit for each power supply to avoid compromising the power redundancy
feature.
The Cisco ASR 1000 Series Routers can be powered by a DC or AC source. Ensure that the equipment
grounding is present and observe power strip ratings. Make sure that the total ampere rating of all
products plugged into the power strip does not exceed 80% of the rating.
Tabl e 3-4 contains specifications for DC powered systems for all Cisco ASR 1000 Series Routers.
Note All Cisco ASR 1000 Series Router AC power supplies require a 20 AMP circuit breaker.
The AC and DC power supplies for the Cisco ASR 1000 Series Routers support different types of power
supply switches. Tabl e 3-5 defines which power supplies the Cisco ASR 1000 Series routers support (a
Standby or an On/Off switch).

Cisco ASR 1004 24 30 40 10 8
Cisco ASR 1002 16 20 30 12 10
For example, the Cisco ASR 1002 Router DC power supply, with 16 Amp input rating must use an AWG #12 gauge wire for a 20Amp circuit breaker and
an AWG #10 gauge wire for a 30Amp circuit breaker.
