Highlights
For switching in the SuperStack
environment, there’s the LinkSwitch
™
family of switching hubs. Choose
from stackable Ethernet, FDDI, and
ATM switching units to segment floor
wiring and improve performance in
workgroups, or to extend more band-
width to individual servers or work-
stations.
Solution 5: LAN Switching and High-Speed Connectivity
LinkSwitch: A
Switching Revolution
in the Workgroup
3Com’s LinkSwitch family of switches
eliminate client/server bottlenecks
with fast, simple, low-cost, highly
manageable designs that have revo-
lutionized workgroup switching.
Performance—Powerful switching
engines extend full 10 Mbps band-
width to the workgroup and up to
155 Mbps to the server or backbone,
eliminating network bottlenecks.
Simplicity—Plug-and-play installa-
tion and drag-and-drop graphical
configuration make adds, moves,
and changes exceptionally easy.
Low Cost—The switches deliver
high performance without the need
for expensive desktop or cabling
changes. They are priced for the
workgroup, making them affordable
for all workgroup applications,
including connecting individual
power users.
Manageability—Transcend manage-
ment gives you at-a-glance monitor-
ing and comprehensive control of the
entire workgroup—switches, hubs,
and adapters. Management tools
combine a high degree of flexibility
with a common look and feel.
SuperStack—Every LinkSwitch
workgroup switch is part of 3Com’s
SuperStack system, allowing you to
enhance connectivity, functionality,
and resilience by simply adding units
to the stack.
Fault Tolerance—For additional
uptime protection, you have the
option of using a Redundant Power
System.
