Fast Ethernet
100 Mbps network communication system based on Ethernet and the CSMA/CD access
method.
IEEE 802.3 Standard
Standard for the physical and electrical connections in local area networks developed by
the IEEE. The IEEE 802.3u standard covers these same issues for 100 Mbps networks.
LED
Light emitting diode on the front panel of the hub used for monitoring a hub or network
condition. An LED display corresponds to a hub condition.
Local Area Network (LAN)
A group of interconnected computers and support devices.
MDI Port (Medium Dependent Interface)
MDI is the IEEE standard for the twisted-pair interface to 10BASE-T (or 100BASE-
TX). This RJ-45 port can be used with straight-through cable to connect the hub to a
network interconnection device, such as another hub or a switch. Pin-out assignments
are shown in Appendix B.
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 hub to any device that has a standard network
interface (e.g., workstation, server or router). Pin-out assignments are shown in
Appendix B.
RJ-45 Connector
Most common terminator for twisted-pair wiring.
