    100BASE-TX traffic requires a Category 5 or higher cable. 10BASE-T traffic can use Category 3 or Category 4 cables. When you connect the switch to workstations, servers, routers, and Cisco IP Phones, be sure that the cable is a straight-through cable. When you connect the switch to switches or hubs, use a crossover cable.
