Operation Manual

Getting Started — The Basics

Getting Started — Omega

ATI’s Omega management software is pre-installed and immediately

operational once power is applied. Conﬁguring your network depends,

however, upon the requirements of your particular environment.

Your switch can operate either standalone when the backbone port is not

connected to an ATM network — or as an Ethernet switch/ATM Emulated

LAN when the backbone port is connected to an ATM network and

functioning.

Omega management enables you to access and conﬁgure your switch to

ELANs — with or without a network accessible LECS.

That is, prior to Release 2.4, an “ATMcentric” design mandated that before

switching any packets on the Ethernet ports, the switch HAD to use the

LECS to connect to, and maintain, an ELAN. Further, if the connection to

the ELAN was dropped for any reason, then any device communicating on

that ELAN would cease to operate.

In short, prior to this release, given that a standalone switch would not know

which ELAN to join, it followed that, if the LECS was not available, it was

neither possible to conﬁgure devices nor forward packets.

Further, the “downing” of an ELAN (the LES is inoperative) and the

subsequent change in the network topology, would force the switch to

reconﬁgure.

Release 2.4 addresses, and resolves, these issues by providing an alternative

to LECS address determination. Your switch now has the ability to perform

local Ethernet forwarding for devices when the LECS is unavailable, the

LES for an ELAN is unavailable, the ATM 4002 card is not present, or even if

the ATM ﬁber connection is not present. All that is required is that you

activate the Port to ELAN configuration screen (from the LAN

emulation submenu), and configure your user-designated ports to

“FIXED.” This process is discussed later.

Remember, however, that AT-S13, v2.4 software, still maintains the ability to

conﬁgure devices/ports through the LECS.
