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.

Table 3-4contains specifications for DC powered systems for all Cisco ASR 1000 Series Routers.

	Table 3-4	Cisco ASR 1000 Series Router DC Power Supply System Input Requirements
Cisco ASR 1000
Series Router DC
Power Supply	System Input Rating (Amps)		Circuit Breaker Amps			AWG # Wire
			Minimum	Maximum	Minimum		Maximum
Cisco ASR 1006	40		Always 50		Always AWG #6 wire
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.

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. Table 3-5defines which power supplies the Cisco ASR 1000 Series routers support (a Standby or an On/Off switch).
