The ASR1004-PWR-DC is the Cisco ASR1004 DC Power Supply, a -48 VDC supply for the Cisco ASR 1004 Router. It has a 24 A input rating and works with a 30 A to 40 A circuit breaker and AWG #10 to #8 wire.
The supply has a terminal block with a plastic cover, status LEDs, a DB-25 alarm connector, a fan, an On/Off switch and a handle. Shielded cables are required on the DB-25 alarm connector to meet FCC/EN55022/CISPR22 Class A emissions limits.
The chassis ground connection is made before the supply is installed, and at the supply the ground connection is made first and disconnected last. Input cable lugs are dual-hole with a 45-degree angle tongue and fit over a #10 power terminal stud, and the ground cable should be at least 6-AWG multistrand copper with a dual-hole lug that fits M6 studs at 0.625-inch (15.88 mm) centers. Polarity is confirmed by measuring the voltage between the cable leads.
The ASR 1004 holds two power supplies at the rear, and AC and -48 VDC supplies cannot be combined in one chassis. The spare ordering number is ASR1004-PWR-DC=. The router that takes it is the ASR1004 Cisco ASR 1004 Aggregation Services Router chassis, and more modules are in Cisco interface cards.
