Cascade Switch

The cascade switch provides cable wiring flexibility on the last UTP Port (i.e., Port 16 or Port 24) for connecting to a workstation or cascading to another hub. By default, the last UTP port is set to “Crossover” (left side) as a standard, internally-crossed port, or MDI-X port. Depending on the wiring of your UTP cable (normally “Straight-Thru”), the port is used to connect a workstation.

For cascading to another hub using a straight-thru cable, move the cascade switch to “Straight-Thru” (right side). If a crossover UTP cable is used to cascade to another hub, leave the cascade switch in the “Crossover” position.

connections (MDI to MDI)

MDI (Media Dependent Interface) is the standard that defines the mechanical and electrical configuration of a UTP port. For any two devices to communicate on the network, the transmitter of one device must be connected to the receiver of the other device. This can be achieved by using a crossover cable, or by using one MDI-X port that implements the cross-over internally.
