Power Supplies for Cisco ASR 1004 Router

The Cisco ASR 1004 Router can support up to 735 W output (AC and DC input). The 735W power supply module consists of either an AC or DC input with two DC voltage outputs: 12V and 3.3V.

Each power supply module contains three internal fan modules and provides the forced air cooling for the chassis. These power supply modules contain a monitor circuit to determine the status of fan speed and operation along with LED status indicating fan errors.

The system temperature operation is 0 to 40C and –5C to +55C.

•AC System—AC power input is an IEC 320-type power inlet, 15A service connector. The AC input side contains a front panel with provisions for mounting screw, built in handle to remove the power supply, three status LEDs, and fans for power supply and system cooling.

•DC System—Three-position terminal block-style connector, with labeled connections for - (–48/60 V input) and + (–48/60 V Return) and GND (earth ground symbol). The DC input side contains a front panel with provisions for mounting screw, built in handle to extract the power supply, three status LEDs, and fans for power supply and system cooling.

See Appendix A, “Cisco ASR 1000 Series Routers Specifications.” for detailed power supply specifications.

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 1004 AC Power Supply

This section provides information about the AC power supplies on the rear of the Cisco ASR 1004 Router. The power supply module contains three fans mounted in the power supply module. A total of six fans are used to cool the ASR 1004 system and power supply. The airflow direction is front to back.
