Chapter 1
Getting Started
This chapter provides an overview of the Omega management interface
and contains the different procedures for starting an Omega
management session. The sections in this chapter include:
❑ Overview on page 22
❑ Starting a Local Omega Session Using th e RS232 Port on page
23
❑ Starting an Omega Session from a Web Browser on page 28
❑ Starting a Remote Omega Session with Telnet or an SNMP
Management Program on page 32
❑ Connecting to a Remote Switch on page 33
❑ Menu Tree on page 34
21
Getting Started
Overview
The Omega interface simplifies the task of managing your Allied Telesyn
AT-8216FXL, AT-8224XL, and AT-8288XL Series Fast Ethernet switches.
This menu-oriented interface, which comes pre-installed on the switch
along with the AT-S24 software, enables you to configure and manage
all of the switch parameters, such as the IP address, the gateway address,
and the subnet mask of the switch. You can also use the interface to
create virtual LANs, view performance statistics, and create port trunks.
There are three different ways that you can access the Omega
management interface to configure and manage a switch. They are:
❑ Using the RS232 port on the front panel of the switch. This creates
a Local Omega session.
❑ Using a web browser, such as Netscape Navigator.
❑ Using Telnet.
You can also manage a switch using a SNMP program, such as HP
Overview; however, this method does not use the Omega interface.
The different sections in this chapter contain procedures on how to start
an Omega management session for each method. The chapter also
describes the Omega Main Menu and how to move through the
different menu selections.
22
Starting a Local Omega Session Using the RS232 Port
This section contains the procedure for starting a local Omega session by
connecting a terminal to the RS232 port on the switch.
Note
If you are managing the switch in a TCP/IP environment and you are
configuring the IP parameters for the first time, you must access the
Omega program locally using this procedure and assign the switch
an IP address and, if necessary, a gateway address and a subnet
mask.
To start a local Omega session, perform the following procedure:
1. Connect a terminal or PC with a terminal emulator program to the
RS232 port on the switch.
2. Configure the terminal or terminal emulator program as follows:
❑ Baud rate: 9600
AT-S24 Version 2.01 User’s Guide
❑ Data bits: 8
❑ Stop bits: 1
❑ Parity: None
❑ Flow con t ro l: None
❑ Emulator: VT100
Note
The default settings for the switch’s RS232 port as listed above are
for a DEC VT100 or ANSI terminal, or an equivalent terminal
emulator program. Once you have started an Omega session, you
can change these values, as explained in Chapter 2, Managing a
Switch.
3. Press the <Return> key.
4. If prompted for a password, enter the password for the Omega
interface. The default is no password. You can later configure a
password. For instructions, refer to Chapter 7, Configuring the
Omega Interf a c e .
The Omega Main Menu is displayed. Refer to the next section for a
description of the menu.

Note
If you are configuring the switch for the first time and the switch is
in a TCP/IP network, go to Chapter 2, Managing a Switch for
instructions on how to assign the switch an IP address, subnet mask,
and gateway address.

Starting an Omega Session from a Web Browser
This section contains the procedure for starting an Omega session from
a web browser.
Note
You cannot use a web browser to manage a Fast Ethernet switch if
the switch is part of a non-TCP/IP network.
Before you can manage the switch in a TCP/IP environment, it must have
an IP address. In order to configure the IP parameters for the first time,
you must access the Omega program locally using the switch RS232
port; refer to Starting a Local Omega Sess ion Using the RS23 2 Port on
page 23 for instructions.
To start an Omega session from a web browser, perform the following
procedure:
1. Start your web browser.
2. Enter the IP address of the switch you want to manage in the URL field
of the browser, as shown in Figure 2.
Switch’s IP Addr ess
Note
If the PC with the web browser is connected directly to the switch or
is on the same side of a firewall as the switch, you must configure
your browser’s network options not to use proxies. Consult your
web browser’s documentation on how to configure the browser not
to use proxies.

You can click on certain areas of the switch to activate windows. Clicking
on a port displays the configuration window for that port, which you use
to set the port parameters. Clicking on the RS232 port displays the
configuration window for the terminal port. Finally, clicking on the
switch chassis displays a window that lists the status of all the ports on
the switch.
The Main Menu window contains the Omega menus. This window is
