Switches are relatively inexpensive and easy to install. When operating in full-duplex mode, they provide dedicated bandwidth to workstations. Switches eliminate collisions by creating microsegments between ports to which the two workstations are attached. They are appropriate for small to large LANs with moderate to heavy traffic. In addition to the physical and data link connections, which are Layers 1 and 2, the computers must also be configured with the correct IP network settings, which is Layer 3, so that they can communicate.

This is referred to as a patch cable or horizontal cabling, which is used to connect workstations and a typical LAN. Start this lab with the equipment turned off and with cabling disconnected. Work in teams of two with one person per PC. The following resources will be required:. Several Ethernet cables, which are straight-through and crossover, to choose from for connecting the two workstations.

Step 1 Identify the proper Ethernet cable and connect the two PCs to the switch a. The connection between the two PCs and the switch will be accomplished using a Category 5 or.

Locate two cables that are long enough to reach from each PC to the switch. Attach one end to the NIC and the other end to a port on the switch. Be sure to examine the cable ends carefully and select only a straight-through cable.
