Cisco ASR 1002-X Router Description
+24 VDC Power Supply for the Cisco ASR 1002-X Router
This section provides information about the +24 VDC power supply at the rear of the Cisco ASR 1002-X
Router. The recommended branch circuit breaker for the Cisco ASR 1002-X Router +24 VDC power
supply is a 40 A UL-listed circuit breaker.
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.
