Cisco ASR 1002 Router Power Supply Fans

Cisco ASR 1002 Router system level cooling is provided by two 12 VDC type fans in each power supply module. The fans in each module provide system cooling back-up in the event of a single fan failure. In addition, the fans in each of the power supplies can be powered from a single supply when only one unit is operational. The airflow direction is front to back.

Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than: AC power supplies for the Cisco Aggregation Services Routers: 120 VAC, 20A U.S. maximum. DC power supplies for the Cisco ASR 1006 Router: 50A U.S. maximum; Cisco ASR 1004 Router: 40A U.S. maximum: Cisco ASR 1002 Router: 30A U.S. maximum. Statement 1005

Cisco ASR 1002 Router AC Power Supply

This section provides information about the AC power supplies on the rear of the Cisco ASR 1002 Router.

The Cisco ASR 1002 Router system level cooling is provided by two 12 VDC type fans in each of the two power supply modules. The fans in each module are intended to provide system cooling back-up in the event of a single fan failure. In addition, the fans in each of the power supplies can be powered from a single supply when only one unit is operational. The airflow direction is front to back. The power supplies plug directly into the Cisco ASR1000-RP1 and distributes power back to the midplane.

Guide pins located at the rear of these modules help center locate the modules and reduce stress to the midplane and module mounted connectors. Two captive screws (tool operated latches) are provided on the modules face plate (chassis rear) to secure these modules into the chassis.
