Fast EtherHub 3500 System User’s Guide

FlexBus Ports

SCSI ports found at the backplane of the EtherHub labeled In and Out. These ports are used for linking the hub to other compatible hubs using Accton’s FlexBus 3500 cable.

IEEE 802.3 Standard

Standard for the physical and electrical connections in local area networks developed by the IEEE (Institute of Electrical and Electronics Engineers). The IEEE 802.3u standard covers these same issues for 100 Mbps networks.

In-Band

A way of communicating with a network device via a local network connection.

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.

MAC (Media Access Control)

A portion of the networking protocol that governs access to the transmission medium, facilitating the exchange of data between network nodes.

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 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 switch to any device that has a standard network interface (e.g., workstation, server or router). Pin-out assignments are shown in Appendix B.
