Compatible Systems 900i Connecting an Out-of-Band Management Console, Powering Up the Router

router must first be configured for synchronous operation before connecting to the device. See Chapter 6 - Basic Configuration Guide for configuration information.

You may select either dial-on-demand, always up (i.e., redial if down), or leased line operation. This interface may also be set to receive ISDN or switched-56 incoming calls.

To connect a device, first make sure that both units are powered off. Then, simply connect the supplied RS-232 cable between the router and the device.

ϖNote: The MicroRouter 900i RS-232 interfaces require that your asynchronous line communications device be set to supply the RS-232 DCD signal when a connection has been made. A synchronous RS-232 device should be set to provide DSR.

ϖNote: The MicroRouter 900i includes a special cable to facilitate connections to RS-232 line communications devices. This cable includes support for several asynchronous and synchronous control signals. Off-the-shelf cables generally do not support these signals.

Connecting an Out-of-Band Management Console

If you wish to connect an out-of-band management console, use the supplied cable and connect to the Console interface on the back of the MicroRouter 900i. You can use a dumb terminal or a computer equipped with VT100 terminal emulation.

The default settings for the Console interface are VT100 terminal emulation, 9600 bps, 8 bits, no parity, 1 stop bit, no Flow Control.

Powering Up the Router

Power up any modem, CSU/DSU, or TA before powering up the router. This allows the router to immediately sense whether its secondary inter- face is connected. The exception to this rule is when connecting an RS232 interface to a CSU/DSU. In such a case, you must power up the router before powering up the CSU/DSU. At power-up, the router will take approximately one minute to become visible to CompatiView.

ϖNote: If you want to use Telnet as a management method, you must first configure an IP address into the router using an out-of-band console, or reconfigure the IP address on an IP host or workstation on the same Ethernet segment as the router. See Chapter 5 - Command Line Management for more information.
