The Cisco ASR 1002-X Router has two same-type power supplies in power supply slot 0 and power supply
slot 1. The power supply slot identifiers are zero (0) on the left side of the chassis, rear side, and one (1) on
the right side of the chassis, rear side. The power supply switch is a Standby switch and is not considered a
disconnect.
The +24 VDC power supply uses a spring-loaded terminal block. The input terminal block requires a maximum
of 8 AWG multistrand wiring to support the input current. The terminal block is compliant with safety agencies’
guidelines and the electrical requirements of the supply. Use the tie wraps to dress the input cable wires; there
are two tie wrap tabs on the +24 VDC power supply. The +24 VDC power supply unit is secured into the
system chassis with two captive screws mounted on the faceplate.
The following image shows the +24 VDC power supply for the Cisco ASR 1002-X Router.

When the LED is off, it signals that the +24 VDC output voltage is within the
normal operating range. Output voltage between the minimum limit and maximum
limit will not create an output fail alarm, but output voltages below the minimum
limit or above the maximum limit will create an Output Fail alarm.
When you turn the power supply on, LED turns red for two to three seconds to
test the LED operation before going off.
