Redundancy
The Cisco ASR 907 Router chassis includes a slot for an optional redundant power supply. The redundant
power supply option provides a second power supply to ensure that power to the chassis continues uninterrupted
if one power supply fails or input power on one line fails. Redundancy is supported either with identical power
supplies or a combination of AC and DC power supply. The Cisco ASR 907 Router supports current sharing
between the power supplies.
If you install a redundant power supply on the Cisco ASR 907 Router, we recommend that you connect each
power supply to a separate input power source in order to ensure that the router maintains power in the event
of a power interruption caused by an electrical failure, a wiring fault, or a tripped circuit breaker.
Dying Gasp
The Cisco ASR 907 Router DC power supply does not support the Dying Gasp feature.
Status LEDs
LEDs are also provided on each power supply to indicate the status of the input power and the health of the
power supply. For more information about the LEDs on the Cisco ASR 907 Router, see
