Cisco ASR 907 Router Overview
• 85 VAC to 264 VAC
The power supplies are hot-swappable. They are enclosed to prevent exposure to high voltages, and therefore,
no power cable interlock is required. However the power supplies are automatically shut down when removed
from the chassis. The power supplies are rated to deliver 1200W (~100A at +12VDC) to the other FRUs in
the system and are rated for operation at 5ºC above the chassis operating temperature.
See the below tables for the AC and DC power supply specifications.
