Connecting the M320 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 CIP. To use a laptop, modem, or other auxiliary device, connect it to the appropriate AUX port on the CIP. Both ports accept an RS-232 (EIA-232) serial cable with a DB-9 female connector. One DB-9/DB-9 cable is provided with the router. To connect a device to the CONSOLE port, and another device to the AUX port, you must supply another cable.
To connect a management console or auxiliary device:
- Turn off the power to the console or auxiliary device.
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Connect one end (shown in Figure 1) of a serial cable
with a DB-9 female connector into the appropriate CONSOLE or AUX port (see Figure 2). 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).
For console devices, configure the serial port to the following values:
- Baud rate—9600
- Parity—N
- Data bits—8
- Stop bits—1
- Flow control—none
- Using a 2.5-mm flat-blade screwdriver, tighten the screws on the connector.
- Attach the other end of the cable to the console or auxiliary device.
