Connecting a Console to the Switch

	Remote Console Connection Using a Modem and a PC
	Terminal Emulator or Terminal

N o t e	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.
