Replacing the T640 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 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 connect a management console or auxiliary device:
1. Plug one end of the replacement cable into the appropriate CONSOLE or AUXILIARY
port. Figure 120 on page 274 shows the external device ports on the CIP. The ports
labeled HOST 0 connect to the Routing Engine in the upper Routing Engine slot (RE0),
and the ports labeled HOST 1 connect to the Routing Engine in the lower Routing
Engine slot (RE1).
2. Plug the other end of the cable into the device's serial port.
