2650
As a Segment Switch
The Switch 2650 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 2650. 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 a
1000Base-T port on the switch.
Because the Switch 2650 has the “HP Auto-MDIX” and “IEEE Auto MDI/
MDI-X” features, 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, can be connected to a network backbone through fiber-
optic cabling connected to a Gigabit-SX, -LX, or -LH mini-GBIC 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.
