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 MGMT port on the Routing

Engine. One such cable is provided with the router. For cable specifications, see

“Cable Specifications for Routing Engine Management Interfaces” on page 187. Follow

this procedure:

If a cable is already installed in the MGMT 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 53 shows the connector.

b. Disconnect the cable from the network device.

Plug one end of the replacement Ethernet cable into the appropriate MGMT port.

Figure 52 shows the external device ports on the Routing Engine.

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 Routing Engine. To use a laptop, modem, or

other auxiliary device, connect it to the appropriate AUX/MODEM port on the Routing

Engine. 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 “Cable Specifications

for Routing Engine Management Interfaces” on page 187.

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

If a cable is already installed in the CONSOLE or AUX/MODEM port, perform the

following steps:

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

b. Unscrew the screws that secure the cable connector to the port, using a

2.5-mm flat-blade screwdriver if necessary.
