Connecting the T640 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 AUXILIARY 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 AUXILIARY port, you must supply another cable.

To connect a management console or auxiliary device:

  1. Turn off the power to the console or auxiliary device.
  2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  3. Connect one end (shown in Figure 1) of a serial cable with a DB-9 female connector to the appropriate CONSOLE or AUXILIARY 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).Note

    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

  4. Using a 2.5-mm flat-blade screwdriver, tighten the screws on the connector.
  5. Attach the other end of the cable to the console or auxiliary device.
