Cisco ASR Router 1004 –48 VDC Power Supply
This section provides information about the –48 VDC power supplies on the rear of the Cisco ASR 1004
Router. For the maximum branch circuit for the –48 VDC power supply module, see
The –48 VDC power supply operates within specification from –48 VDC to –60 VDC continuously. The
Cisco ASR 1004 Router has two of the same type power supplies in power supply slot 0 and power
supply slot 1. The power supply slot numbers are on the left side of the chassis and the power supplies
are located on the floor of the chassis.
The –48 VDC power supply input connector is a terminal block style that will allow crimp type lugs
accepting up to AWG #8 wire. The terminal block is compliant with safety agencies' guidelines and
electrical requirements of the supply. The terminal block accepts two-hole lugs (#10 stud) for all
connections with center to center spacing of 0.625 inches. A plastic cover goes over the terminal block
to prevent accidental contact. The connection order is negative (–), positive (+), and GND.
The unit requires a power switch circuit breaker to serve as the main disconnect for the –48 VDC input
to the power supply
into the system chassis with four captive screws mounted on the faceplate.

Color Description
Green LED illuminates green when all fans are operational.
Red The LED illuminates red when a fan failure is detected.
Red LED is red and turned off to signal that the –48 VDC output
voltages are within the normal operating range; output voltage
between the minimum and maximum limits will not create an output
fail alarm, and output voltages below the minimum or above the
maximum will create an output fail alarm.
When you turn the power supply on, the red LED is illuminated for
two to three seconds for testing LED operation before going off.
