Electrical Circuit Requirements
Each Cisco ASR 903 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 903 Routers can be powered by a DC source or an AC source. Ensure that equipment grounding
is present and observe the 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.
