Introducing the ONline System Concentrator

The ONline System Concentrator is a modular, fault-tolerant platform for facility networks. The concentrator has a unique TriChannel® architecture that allows it to run three network protocols concurrently. It is capable of running Ethernet, Token Ring, and FDDI networks - all in the same concentrator.

Ethernet connectivity is available on a variety of major cable types including:

Fiber optic cable

Unshielded and Shielded twisted pair wire

Thin and Thick coaxial cable

Introduction 1 - 1

Figure 1-1 shows a model system that includes each of these cable types. In this diagram, an ONline Ethernet Repeater Module is connected to a 10BASE5 segment via an AUI cable and a transceiver. Also shown is the physical connection between an ONline Ethernet Fiber Module and a 10BASE2 segment, via a fiber cable, fiber media access unit, and IEEE repeater. Unshielded and shielded twisted pair connections to-the-desk are also included in this sample configuration.

Figure 1-1. Multiple 17-Slot Concentrator Environment

Network segments attach to the concentrator through media modules you install into the chassis. The ONline Controller Module, which provides re-timing and re-transmission of received signals, must be installed in one of the concentrator's seventeen slots. The remaining sixteen slots can be configured with any combination of media modules.

1 - 2 ONline 17-Slot System Concentrator Installation and Operation Guide

Back Panel

A power supply and DC fan unit are installed when you receive your concentrator. There is an On/Off switch on the power supply. The power supply should be powered down when you install or remove it. Note that there is no need to power down the concentrator for installation or removal of the media modules. Additionally, you can replace the fan unit with an optional backup power supply to provide power redundancy.

Figure 1-2. ONline System Concentrator Rear View

Front Panel

The concentrator is shipped with 15 blank faceplates and two empty slots. The two slots are left empty because you must install the ONline Controller Module and at least one media module for the concentrator to be functional. As you add media modules to your unit, remove blank faceplates to provide additional slots for the new modules.

Introduction 1 - 3

Figure 1-3. ONline System Concentrator Front View

A cable tray is provided with the concentrator so that cables you attach to the media modules can be run under the unit and out the back − where they will not be in the way. A rack mount kit is also provided for the concentrator and for the cable tray so you can rack mount the entire unit.

ONline System Concentrator Features

This section describes the major features of the ONline System

Concentrator. The features include:

Modular Design

TriChannel® Architecture

Port-Switching Technology

Fault-Tolerance Capabilities

Hot Swapping of Media Modules

Synchronous Backplane

1 - 4 ONline 17-Slot System Concentrator Installation and Operation Guide

Modular Design

The ONline Concentrator's modular design lets you add different media modules (such as fiber, twisted pair, and coaxial) in any combination to connect different types of media segments. A possible configuration is shown in Figure 1-4. You can link segments of different protocols using Token Ring, FDDI, bridging and routing modules.

Every concentrator requires one Controller Module that controls communications between all modules. In addition, a Network Management Module provides sophisticated monitoring and control of the modules in the concentrator. As a rack-mounted unit, the ONline Concentrator can be connected to patch panels to simplify and manage your network cables.

Figure 1-4. Modular ONline Configuration

Introduction 1 - 5

TriChannel Architecture

The ONline System Concentrator's TriChannel architecture lets you run Ethernet, Token Ring, and FDDI networks, all in the same concentrator. This allows a single ONline unit to do the work of three conventional hubs. You can also run multiple Ethernet networks or mixture of Ethernet, Token Ring, and FDDI networks in any combination you want. This architecture is shown in Figure 1-5.

Any module you add to the concentrator can be assigned to any of three networks on its backplane and can be easily moved to another backplane network using either an on-board dip switch or remote network management.

Additionally, any module can be set to “isolated” mode whereby it acts as an isolated network - not connected to the concentrator backplane. This mode lets you isolate users from the main network. This can be useful for security or as a temporary situation to prevent traffic from contaminating the network (for example, if some users are conducting network tests or running at very high loads.)

Port-Switching Technology

Available port-switching modules allow you to assign any port to any backplane network using a network management command. This allows you to perform moves, adds, and changes at the network console, saving costly and time-consuming trips to the wiring closet. It also allows you to get additional bandwidth on demand by switching users to lower volume networks during peak traffic periods.
