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.

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.
