Replacing the Console or Auxiliary Cable on an MX240 Router
To use a system console to configure and manage the Routing Engine, connect it to the
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 RJ-45/DB-9 cable is provided with the router. If you want to connect a
device to both ports, you must supply another cable.
To replace a cable connected to a management console or auxiliary device:
1. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
2. Press the tab on the connector, and pull the connector straight out of the port.
