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.

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 xref table.
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 (xref table see for current rating requirements.) The power supply unit is secured into the system
chassis with four captive screws mounted on the faceplate.
