(MDI-X). Since network cards do not cross their internal wiring to
make a connection, PCs can be connected to these ports with
straight-through cable.
10BASE-T/100BASE-TX hubs and switches, on the other hand, may
have either crossover (MDI-X) or straight-through (MDI) ports. For
this reason, the type of cable used to connect these devices to the
TigerSwitch is determined by the port on the other device, as
shown in the table below. (See Appendix B for further
information on cabling.)
