DC Power Supply LEDs and Connectors for Cisco ASR 1006
This section provides information about the DC power supplies on the rear of the Cisco ASR 1006
Router. The maximum branch circuit for the DC power supply module is 60A and the minimum is 50A.
The DC 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 DC input connector is a terminal block style that supports a AWG #6 wire. The terminal block is
compliant to all safety agencies 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 –48V input and another for –48V RTN. A
plastic cover fits over the terminal block to prevent accidental contact. See Figure 5-18.
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 DC 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.
Figure 2-11 shows the DC power supplies at the rear of the Cisco ASR 1006 Router. The Cisco ASR
1006 Router supports up to two power supplies. The power supply LEDs and connectors on the rear of
the chassis are described in the Table 2-11.
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 AC 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.
