Follow these steps to connect the switch to 10BASE-T, 100BASE-TX, or
1000BASE-T devices:
Step 1 When connecting to servers, workstations, and routers, insert a twisted-pair
straight-through cable in a front-panel RJ-45 connector, as shown in Figure 4-24
and Figure 4-25. When connecting to switches or repeaters, insert a twisted-pair
crossover cable. (See the “Cable and Adapter Specifications” section on page B-5
for cable-pinout descriptions.)
Note When connecting to 1000BASE-T devices, be sure to use a four twisted-pair,
Category 5 cable.
