II Switch 2000 TR
The SuperStack II Switch 2000 TR is a multiport inter-
networking switch for Token Ring networks.
Designed to satisfy the high demand for bandwidth in
expanding Token Ring networks while preserving the
investment in existing equipment, the Switch 2000 TR
provides a natural migration path for network growth
and high-speed technologies, including ATM and
FDDI.
The Switch 2000 TR is a 12-port Token Ring stackable
switch that supports throughput rates of more than
400,000 packets per second. Designed to fit comfort-
ably within the data center or the workgroup environ-
ments, the Switch 2000 TR supports up to 72 rings
per stack at 4 or 16 Mbps.
System Benefits
■ Network segmentation —When used in place of
low- performance PC bridges or routers, the
Switch 2000 TR provides a simple method for seg-
menting Token Ring networks into smaller, more
manageable workgroups.
■ Increased bandwidth —A key benefit of segmen-
tation is reduced traffic load, which translates into
increased bandwidth and improved manageability.
