MDI-X Port (Medium Dependent Interface - Crossed)

This RJ-45 port, which crosses the receive and transmit signals internally, can be used
with straight-through cable to connect the switch to any workstation or server that has a
properly installed network adapter card. Pin-out assignments are shown in Appendix B.

RJ-45 Connector

Most common terminator for twisted-pair wiring.

Shielded Twisted-Pair (STP)

Twisted-pair wire covered with an external aluminum-foil or woven-copper shield
designed to reduce excessive noise pick up or radiation.

Station Port

The SwitcHub MDI-X port or the fiber optic port can be used for connecting the switch
to any workstation or server that has a properly installed network adapter card.

Unshielded Twisted-Pair (UTP)

Cable composed of two insulated wires twisted together to reduce electrical
interference; used in common telephone cord.
