As a Segment Switch
The Switch 2124 also works well as a segment switch. That is, with its high
performance, it can be used for interconnecting network segments — simply
connect the network hubs that form those segments to the switch, or you can
also connect other switches.
In the illustration above, two “Fast” Ethernet hubs with PCs, printers, and local
servers attached, are both connected to a Switch 2124. The devices attached
to the two hubs can now communicate with each other through the switch.
They can also all communicate with the server that is connected to the switch.
Because the Switch 2124 has the “HP Auto-MDIX” feature, the connections
between the switch and the hubs, and between the switch and end nodes or
servers can be through category 5 “straight-through” or “crossover” twisted-
pair cable. Category 3 or 4 cable can also be used if the connection is 10 Mbps
only. In all cases, the device ports must be configured to auto negotiate the
link characteristics for this feature to work.
The switch, in turn, is connected to a network backbone through fiber-optic
cabling connected to an HP 100-FX SC Transceiver installed in the switch.
Now, all the devices on these network segments can access other network
resources that are connected elsewhere on the network backbone.
