Cisco ASR 1001 Router Power Supply Fans
Cisco ASR 1001 Router system-level cooling is provided by seven fans in each chassis at rated 12 VDC
voltage. Fan failure is determined by fan rotation sensors. A fan failure state is declared when the actual
speed of a fan is less than 60% of its nominal speed. The fans provide system cooling backup in the event
of a single-fan failure. The airflow direction is front to back.
This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that
