MAKING NETWORK CONNECTIONS

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.)
