Configuring the Serial Console Port as a TTY Console
To configure the console serial port as a TTY Console:
1. In the System Configuration section of the Web Agent window, select Console
Configuration. The Console Configuration dialog box opens.
2. Click TTY for your console type and click SELECT. The Console Port
Configuration dialog box opens.
3. Use Table 3-17 to set your console serial port settings:
4. Click APPLY to save your changes, or CANCEL to restore previous settings.
Connecting a Modem
In order to use the serial console port as a PPP console, you must connect a modem to
the switch. When you use the specified serial cable and connectors, the switch will
convert the normal DCE interface to a DTE interface that is used by modems.
When the switch is configured for PPP mode, it will periodically send the modem config
string from the serial console port. This will synchronize the baud rates between the
modem and the console port and configure the modem to operate with the switch’s DTE
interface.
The switch does not use any output signals except for TXD. It uses the DTR (converted to
DSR by the specified cable and connectors) input connected to the modem DCD output,
to detect that the modem is connected. It supports XON/XOFF flow control (or none).
To connect a modem:
1. Attach a DB25M-RJ45 (P/N 38210003)connector to the modem.
2. Attach the DB9M-RJ45 MDCE connector to the switch’s serial console port on the
front panel of the switch.
