Replacing the Management Ethernet Cable

To connect the Routing Engine to a network for out-of-band management, connect an Ethernet cable with RJ-45/RJ-45 connectors to the ETHERNET port on the CIP. One such cable is provided with the router. For cable specifications, see Routing Engine Interface Cable and Wire Specifications on page 74. Follow this procedure:

1.If a cable is already installed in the ETHERNET port for the relevant Routing Engine, perform the following steps:

a.Press the tab on the connector and pull the connector straight out of the port. Figure 67 shows the connector.

b.Disconnect the cable from the network device.

2.Plug one end of the replacement Ethernet cable into the appropriate ETHERNET port. Figure 66 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.

Replacing the Console or Auxiliary Cable

To use a system console to configure and manage the Routing Engine, connect it to the appropriate CONSOLE port on the CIP. To use a laptop, modem, or other auxiliary device, connect it to the appropriate AUXILIARY port on the CIP. Both ports accept an RS-232 (EIA-232) serial cable with DB-9/DB-9 connectors. One such cable is provided with the router. If you want to connect a device to both ports, you must supply another cable. For cable specifications, see Routing Engine Interface Cable and Wire Specifications on page 74.

To connect a management console or auxiliary device, follow this procedure:

1.If a cable is already installed in the CONSOLE or AUXILIARY port, perform the following steps:

a.Turn off the power to the console or auxiliary device.
