Daisy-Chain Port
MDI port on the SwitcHub. Port 1 can be used to connect the fast Ethernet switch to
other compatible switches or other network interconnection devices.
Ethernet
A network communication system developed and standardized by DEC, Intel, and
Xerox, using baseband transmission, CSMA/CD access and logical bus topology, and
coaxial cable. The successor IEEE 802.3 standard provides for integration into the OSI
model and extends the physical layer and media with repeaters and implementations that
operate on fiber optics, broadband, and twisted-pair.
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 SwitcHub used for monitoring a switch or
network condition. An LED display corresponds to a switch 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 UTP interface to 10BASE-T. This RJ-45 port can be
used with straight-through cable to connect the switch to a network interconnection
device, such as another switch or a router. Pin-out assignments are shown in Appendix
B.
