Setting Up the Switch
Configuring the Serial Console Port as a PPP Console
You can reconfigure the serial port as a PPP console to support a dial-in PPP
connection using either the Web Agent or the CLI. Before you can do so,
however, you must connect a modem to the switch.
* Note: If you do not configure an IP address for the PPP serial
interface, the switch immediately sends the modem
configuration string. If you type TTY, you will re-access the
CLI login prompt.
Connecting a
Modem After you connect a modem to your switch with the specified serial cable
and connectors, and configure the serial port in PPP mode, the switch will
convert the normal Distributed Computing Environment (DCE) interface to
a Data Terminal Equipment (DTE) interface that is used by modems.
It then periodically sends the modem configuration string from the serial
console port. This synchronizes the baud rates between the modem and the
console port and configures the modem to operate with the switch’s DTE
interface.
To connect a modem ( Figure 2-16 ):
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.
