Power Supplies for the Cisco ASR 1006 Router
–48 VDC Power Supply LEDs and Connectors for Cisco ASR 1006
Note
The information in this section applies to the ASR1006-PWR-DC power supply. If you are using the
ASR1013/06-PWR-DC power supply, see the
“–48 VDC Power Supply LEDs and Connectors for Cisco
ASR 1013” section on page 2-47
.
The maximum branch circuit for the –48 VDC power supply module is 60 A and the minimum is 50 A.
The –48 VDC power supply operates within specification from –48 VDC to –60 VDC continuously. The
Cisco ASR 1006 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 double-hole lugs, one for –48 V input and another for –48 V RTN. A
plastic cover fits over the terminal block to prevent accidental contact. See
Figure 6-23
.
Note
The studs on the terminal block are similar to the safety ground device on the side of the Cisco ASR 1006
Router. For information on the safety ground lug on the side of the chassis.
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 80 VDC
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.
