EtherHub 1500 System User’s Guide
A
Ethernet
A network communication system developed and standardized by DEC, Intel, and Xerox, using baseband transmission, CSMA/CD access, logical bus topology, and coaxial cable. The successor IEEE
802.3standard 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 unshielded
FlexBus 1500 Ports
STP ports found at the backplane of the EtherHub labeled BUS IN and BUS OUT. These ports are used for linking the hub to other compatible hubs using Accton’s FlexBus 1500 STP cable.
Jabber
Refers to an abnormal Ethernet frame transmission. The frames causing jabber are normally much too long. It may come from a malfunctioning Ethernet card and may cause data loss for all network users.
LED
Light emitting diode on the front panel of the EtherHub used for monitoring a hub or network condition. A LED display corresponds to a hub condition.
MIB
An acronym for Management Information Base. It is a set of database objects that contains information about the device. Note that MIB II and Bridge MIB are simply subordinate components of the overall MIB.
