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 22Starting a Local Omega Session Using th e RS232 Port on page

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: 8Stop bits: 1Parity: 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.

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 displayed in a reduced format when you first start a web-based Omega session. To enlarge it, click on the window. Figure 4 is an example of the Omega Main Menu.
