Cisco ASR 1002 Router Description Chapter 8 Cisco ASR 1002 Router Overview and Installation 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. Figure 8-8 shows the +24 VDC Power Supply for the Cisco ASR 1002 Router.
