Single System 2000 10Base-T workgroup hubs can serve as stand-alone units for entry-level LANs connecting up to sixteen users. As requirements grow, new hubs can be added to create a cluster supporting up to 80 nodes, delivering a scalable solution that simplifies network configuration while protecting original investments.
A variety of management options are also available, ranging from local hub management to the powerful, SNMP-based Advanced Analyzer (TM) solutions. Users implement the solution that best meets their needs, eliminating the requirement for large up-front management investments.
The System 2000 family of 10Base-T workgroup hubs consists of three product sets: the Model 2803/2804; the Model 2813/2814; and the Model 2813SA/2814SA. In stand-alone configurations, the Model 2803 and Model 2804 offer simple connectivity and low-level management. The Model 2813 and Model 2814 provide connectivity and a choice of Standard and Advanced agent management options. The Model 2813SA and Model 2814SA deliver connectivity and Advanced Analyzer management capabilities.
The Model 2803 and Model 2804, based on the Am79C980 multi-port repeater chip from Advanced Micro Devices, provide a simple, low-cost solution for entry-level Ethernet LANs. Both hubs feature sixteen modular RJ-45 unshielded twisted-pair host ports, as well as front-panel AUI (Model 2803) or ST-type 10Base-FL-compatible (Model 2804) up-ports for connecting to a variety of network backbones. A series of front-panel LEDs report hub traffic, collisions, management control and expansion status, while per-port LEDs indicate link and partition status for individual connections.
In a stand-alone configuration, simple local management operations can be performed on the Model 2803 and Model 2804 through an ASCII terminal connected to a front-panel port, allowing users to monitor link and partition status as well as enable and disable individual ports.
The System 2000 10Base-T workgroup hubs support a unique expansion feature in which up to four Model 2803/04s can be attached to a single Model 2813/14, creating a manageable cluster supporting up to 80 users.For growing network environments, the System 2000 allows up to four Model 2803s or Model 2804s to be stacked with a single Model 2813/2814 or Model 2813SA/2814SA, creating a manageable 10Base-T cluster supporting up to 80 users. In a cluster arrangement, SNMP management is extended to all hubs, enabling the entire stack to be managed from a central console. The five-hub stack also acts as a single repeater, providing configuration ease and flexibility for designing large networks.
Hubs are linked via Model 988 Expansion Cables, which serve as a virtual backbone between concentrators. An expansion cable is included with each Model 2803 and Model 2804.
