What Is Needed

Connecting to Console Port for Local Management

This section describes how to connect an RS232 DTE interface cable from a PC, a VT series terminal, or a modem to an A2H124‐24FX for out‐of‐band sessions using CLI commands.

Note: When switches are connected in a stack configuration and all stacking cables are connected before powering up the switches, one switch in the stack will be automatically designated as the Manager of the stack and its Console port will remain active. All other switches will become Member switches and their Console ports will be deactivated.

The following is a list of user‐supplied DTE interface cables that may be needed to connect the DB9 male Console port connector on the switch. The cables are terminated by a DB9 female connector at one end, and by one of three type connectors at the other end, depending on the type connection needed for the remote device. The cables that may be needed are as follows:

•DB9 female‐to‐DB9 female

•DB9 female‐to‐DB25 female

•DB9 female‐to‐DB25 male

Using a DTE modem DB9 female‐to‐DB9 female cable, you can connect products equipped with a DB9 DTE male console port to an IBM or compatible PC running a VT series emulation software package.

Using a DTE modem DB9 female‐to‐DB25 female cable, you can connect products equipped with a DB9 DTE male console port to a VT series terminal or VT type terminals running emulation programs for the VT series.

Using a DTE modem DB9 female‐to‐DB25 male cable, you can connect products equipped with a DB9 DTE male console port to a Hayes compatible modem that supports

9600 baud.

The cable used must connect the Console port Received Data, Pin 2 to the Transmitted Data pin at the other end of the cable. The connection from the Console port Transmitted Data, Pin 3 (must be connected) to the Received Data pin cable connection at the other end of the cable. The DB9 Console port pin assignments are shown in Figure 3‐11.
