Connecting the M120 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 craft interface. To use a laptop, modem, or other
auxiliary device, connect it to the appropriate
AUX
port on the craft interface. Both ports
accept a cable with an RJ-45 connector. One RJ-45/DB-9 cable is provided with the
router. To connect a device to the other port, you must supply another cable. For cable
specifications, see “Routing Engine Interface Cable and Wire Specifications for the M120
Router” on page 246.
To connect a management console or auxiliary device:
1.
Turn off the power to the console or auxiliary device.
2.
Plug the female end (shown in Figure 43 on page 83) of the provided serial cable into
the appropriate
CONSOLE
or
AUX
port. Figure 44 on page 84 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.
Using a 2.5-mm flat-blade screwdriver, tighten the screws on the connector.
4.
Attach the other end of the cable to the console or auxiliary device.
