Migrating to High-speed Technologies

Managers want to migrate to FDDI, ATM, or TR-in-FE easily. Using Switch 2000 TRs, critical resources attach directly to high-speed technologies while preserving the investment in Token Ring hardware. They also merge easily with existing net- work management applications. These features allow network managers to introduce additional switches, servers, and sta- tions seamlessly via direct connections. Switch 2000 TRs can be contained in data centers while remaining connected to high-speed links with single ATM, FDDI, or TR-in-FE module.
