Installing the Power Supply
The Cisco ASR 903 Router provides the following power supply:
• DC power
• 900 W DC power: –40VDC to –72VDC
The DC power supply provides option to connect with two different sources (dual feed); positive (+) and
negative (-) are marked on the PSU terminals.
Each power supply provides a dual primary input power connection.
The power supply must be wired before plugging the power supply in the chassis. Ensure the branch circuit
breaker is turned off. Only after installing the power supply in the chassis, should the branch circuit breaker
be turned on. The branch circuit breaker must be turned off before unplugging the power supply.Read the
installation instructions before connecting the system to the power source. Statement 10
