Connecting the M120 Router to a Network for In-Band Management

To connect the Routing Engine to a network for out-of-band management, connect an Ethernet cable with RJ-45 connectors to the ETHERNET port on the craft interface. One such cable is provided with the router. For cable specifications, see Routing Engine Interface Cable and Wire Specifications for the M120 Router. To connect the Routing Engine to a network for out-of-band management:

1. Turn off the power to the management device.
2. Plug one end of the Ethernet cable (Figure 1 shows the connector) into the appropriate ETHERNET port on the CIP. Figure 2 shows the external device ports on the CIP. The ports labeled HOST 0 connect to the Routing Engine in the upper Routing Engine slot (RE 0), and the ports labeled HOST 1 connect to the Routing Engine in the lower Routing Engine slot (RE 1).
3. Plug the other end of the cable into the network device.
