Connecting to Console Port for Local Management

Stack Initialization Overview

When you install and connect all the stacking cables to the switches in the stack before
applying power to the switches, the following occurs:
• The switch that will manage (Manager) the stack is automatically established with all
other switches established as Member switches in the stack. When the switches
complete their initializations, one of the switches in the stack will illuminate its
Manager LED, indicating that it is the stack Manager. The Manager LED on each
Member switch will be off.
• The hierarchy of the switches that will function as backup Manager is also determined
in case the current Manager malfunctions, is powered down, or is disconnected from
the stack.
• The Console port on each Member switch will provide only the unit number. Only the
Console port on the Manager switch is active and provide a CLI for out‐of band
configuration to set the IP address, password, and other settings.
Once you know which switch is the Manager, proceed to "Connecting to Console Port for
Local Management" on page 3‐18.

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 A2H254‐16 for out‐of‐band sessions using CLI commands.

What Is Needed

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.
3-18 Hardware Installation
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.
