Twisted-Pair Devices
Each 10BASE-T and 100BASE-TX device requires an unshielded
twisted-pair (UTP) cable with RJ-45 connectors at both ends.
For 10BASE-TX connections, two pairs of Category 3, 4 or 5
cable are required. 100BASE-TX connections require two pairs
of certified Category 5 cable.
Cabling Guidelines
Every twisted-pair connection must have a wiring crossover to
transmit and receive data. For convenience, the crossover is
built into all ports that are labeled with an “x”—these are called
fixed crossover ports. Since network cards do not have a built-
in crossover, PCs can be connected to these ports with straight-
through cable. See Appendix A for cabling pinouts.
Hubs (and other switches) may have either crossover or straight-
through ports. For this reason, the type of cable used to con-
nect these devices to a TigerSwitch 16 unit is determined by the
port on the other device, as shown in the table below.
