Gigabit Ethernet LAN and WAN connectivity
An organization supporting a mixture of 10/100 Mbps switched
and shared desktop connections has migrated to a Gigabit
Ethernet backbone.
3Com has taken an early lead in the Gigabit Ethernet market by
providing the ability to utilize this new high-speed technology
while protecting your existing network infrastructure investment.
In this configuration, the SuperStack II system in the basement
comprises a Switch 9300, a Switch 3900, and an Advanced
Redundant Power System for added resilience. The Switch 9300
provides the Gigabit Ethernet switching backbone and links
to Gigabit Ethernet servers while the Switch 3900 provides
unconstrained access to a large Fast Ethernet server farm. This
configuration provides the fastest backbone solution and fastest
server access for all floors.
On the first floor, the SuperStack II Switch 3900 provides line-
rate services to power users directly connected to switched Fast
Ethernet ports.
On the second floor, the SuperStack II Switch 3300 and Switch
1100 provide network connectivity to switched 10 Mbps and
100 Mbps users, and the use of an optional SuperStack II Switch
1000BASE-SX module provides Gigabit Ethernet support.
On the third floor, the SuperStack II Switch 3300 provides line-
rate services to power users on switched Fast Ethernet as well
as switched 10 Mbps services to less demanding users, and con-
nects shared 10 Mbps and 10/100 hubs to the Gigabit Ethernet
backbone. The network is managed at the Transcend network
management console.
