Note For remote console management, use a pair of full-duplex, asynchronous
(character-mode) modems as shown in figure 3-2.
1. Before installing the modems, make sure they are both correctly initial-
ized. Refer to appendix B, “Modem Configuration” for the correct initial-
ization strings.
2. At the site where the Switch 208/224 is installed:
a. Connect the modem to the Switch Management Module’s console port
using a standard “straight-through” RS-232-C modem cable. (For
modem cable pin-outs, refer to “Modem Cable Pin-Out” on next page.)
b. If necessary, configure the PC or terminal to operate with the current
serial link configuration of the Switch Management Module.
3. At the site where the console is to be located, connect the PC emulating
a terminal, or a terminal to the modem using a standard RS-232-C modem
cable. Make sure the terminal and modems are functioning properly, then
establish the link between the terminal’s modem and the switch’s modem
according to the modem instructions.
