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 fiberoptic 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. 2-20
