Installing the Switch 2124 Example Network Topologies Example Network Topologies This section shows you a few example network topologies in which the Switch 2124 is implemented. For more topology information, see the HP network products World Wide Web site, http://www.hp.com/go/hpprocurve. As a Desktop Switch Server twisted-pair "straight-through" or "crossover" cables Switch 2124 PCs and peripherals Installing the Switch 2124 Note The Switch 2124 is designed to be used primarily as a desktop switch to which end nodes, printers and other peripherals, and servers are directly connected, as shown in the above illustration. Notice that the end node devices are connected to the switch by "straight-through" or "crossover" twisted-pair cables. Either cable type can be used because of the "HP Auto-MDIX" feature on the Switch 2124. The HP 100-FX SC Transceiver, when installed in a Switch 2124, operates only at 100 Mbps and full duplex. It cannot operate at half duplex. The illustrations on the next two pages show fiber-optic connections between the HP 100-FX SC Transceiver installed in Switch 2124 units and other 100Base-FX devices. Because of the fixed full-duplex operation of the transceiver in the Switch 2124, the device at the other end of any such connection must be configured the same: 100 Mbps, full duplex, or the connection will not operate correctly. 2-14
