24 VDC Power Supply for Cisco ASR 1002 Router
This section provides information about the +24 VDC power supplies on the rear of the Cisco ASR 1002
Router. The recommended branch circuit breaker for the Cisco ASR 1002 Router +24 VDC power supply is
a 40 A UL listed circuit breaker.
The Cisco ASR 1002 Router has two of the 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 and one (1) on the right
side of the chassis rear. 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 maximum
8AWG multi-strand wiring to support input current. 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 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 Router.
