Power Supplies for the Cisco ASR 1013 Router
–48 VDC Power Supply LEDs and Connectors for Cisco ASR 1013
This section provides information about the –48 VDC power supplies on the rear of the Cisco ASR 1013
Router. The maximum branch circuit for the–48 VDC power supply module is 60 A and the minimum
is 50 A.
Note
The information in this section applies to the ASR1013/06-PWR-DC power supply. The Cisco ASR 1013
Router and the Cisco ASR 1006 Router support this power supply.
The –48 VDC power supply operates within specification from –40.5 VDC to –72 VDC continuously.
The Cisco ASR 1013 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 input connector is a terminal block style that supports a AWG #6 wire. The terminal block
is compliant with safety agencies’ guidelines and electrical requirements of the supply. Use the tie wraps
to dress the input cable wires. There are three tie wrap tabs on the power supply.
The terminal block accepts two-hole lugs, one for the –48 V input and the other for the –48 V RTN. A
plastic cover is fitted over the terminal block to prevent accidental contact.
Note
The studs on the terminal block are similar to the safety ground device on the bottom rear of the Cisco
ASR 1013 Router. For information on the safety ground lug on bottom rear of the chassis, see the
“Attaching a Chassis Ground Connection” section on page 10-302
.
The unit requires a power switch circuit breaker to serve as the main disconnect for the –48 VDC input
to the power supply. The circuit breaker meets international safety requirements and supports 80VDC
and has a current rating of 50 A. The power supply unit is secured into the system chassis with four
captive screws mounted on the faceplate.
FAN OK
Bi-color LED indicates
fan status
Green
LED illuminates green when all fans are operational.
Red
The LED illuminates red when a fan failure is detected.
OUTPUT FAIL
Power supply activity
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.
