Power Supplies for the Cisco ASR 1004 Router
The Cisco ASR 1004 Router can support up to 735 W output (AC and –48 VDC input). The 735 W power
supply module consists of either an AC or –48 VDC input with two DC voltage outputs: 12 V and 3.3 V.
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 (ground symbol). The –48 VDC 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 xref Appendix A, “Cisco ASR 1000 Series Router Specifications” for detailed power supply specifications.
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

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. A total of six fans are used to cool the ASR 1004 system and
power supply. The airflow direction is front to back.
Power supply modules with internal fan modules install into the rear of the chassis. These modules contain
handles to ease installation and removal. The AC power supply has a front panel mounted switch that powers
on and off the power supply. This switch will not disconnect the AC line, but will act only as a standby switch
to the power supply. The front panel includes a mechanical guard to prevent the standby switch from being
tripped due to accidental contact.
Guide pins located at the rear of these modules help center locate the modules and reduce stress to the midplane
and module mounted connectors. Four captive screws (tool operated latches) are provided on the modules
face plate (chassis rear) to secure these modules into the chassis.
