2.10 Applications
The 8000X Port Modules are factory and field configurable. This (and the
stacking feature) provides for easy expansion of the network, and it provides flexibility
to adapt to new fiber port connector types as technology changes. The flexibility of the
Magnum 8000X makes it the choice for applications that require a flexible and
adaptable 10/100 hub.
See also Section 1.0, Technical Specifications, for additional Magnum 8000X
information that may indicate suitable applications.
Example 1: Upgrade, Expansion, Fiber Flexibility : A University library has fiber
cabling installed in the building from the wiring closet to each PC. They have operated
the network setup at 10 Mbps. They have five users, a 10Mbps print server, and
Internet access. Now they require higher bandwidth to accelerate their network. They
want to upgrade three of their present users to 100Mbps speed and expand for another
five 100Mbps users (all with fiber), and they expect a few more users next year.
A Magnum 8000X Dual-Speed Fiber Hub handles all of the users at 10 Mbps
and 100Mbps over fiber and copper in the same hub unit. Port modules can be changed
or added over time to suit expansion and additional changes. The 8000X is initially
configured with eight ports at 100Mbps fiber, two ports at 10Mbps fiber, and three
10/100 RJ-45 copper ports. The Magnum 8000X not only increases the network’s
bandwidth and efficiency, but it also handles existing 10Mbps nodes over fiber in a
economical way. The print server stays at 10Mbps over twisted pair wiring, and is
accessible by all users. The file server and the Internet access, devices located adjacent
to the 8000X, operate over twisted pair at 100Mbps.
A diagram of the installation is shown here.
Example 2: Security, Fiber Flexibility: In a government intelligence agency where a
secure network is the first priority, the possibility of eavesdropping (as is possible with
copper wiring) must be prevented. Fiber LANs are regularly used to connect to each
desktop and each node.
