Connecting the MX240 Router to a Network for Out-of-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 Routing Engine. One
Ethernet cable is provided with the router. To connect to the ETHERNET port on the
Routing Engine:
1. Turn off the power to the management device.
2. Plug one end of the Ethernet cable (Figure 77 on page 212 shows the connector) into
the ETHERNET port on the Routing Engine. Figure 76 on page 212 shows the port.
3. Plug the other end of the cable into the network device.

Connecting the MX240 Router to a Management Console or Auxiliary Device
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 AUX port on the Routing Engine. Both ports accept a
cable with an RJ-45 connector. One serial cable with an RJ-45 connector and a DB-9
connector is provided with the router. To connect a device to the CONSOLE port and
another device to the AUX port, you must supply an additional cable.
To connect a management console or auxiliary device:
1. Turn off the power to the console or auxiliary device.
2. Plug the RJ-45 end of the serial cable (Figure 79 on page 213 shows the connector)
intothe AUX port or CONSOLE port on the RoutingEngine.Figure78 on page 213 shows
the ports.
3. Plug the female DB-9 end into the device's serial port.
