Initialize and Setup
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 2-18):
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.
