HP 100Base-T Hubs Installation and Reference Guide

Glossary 3

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 or hub to any device that has a standard network interface (e.g.,

workstation, server or router). Pin-out assignments are shown in Appendix B.

MIB (Management Information Base)

An acronym for Management Information Base. It is a set of database objects that contains

information about the device.

MII (Media Independent Interface)

IEEE’s specifications for a multi-media interface that supports 100Base-TX, 100Base-T4, 100Base-FX

or 10Base-T.

Network Management Station

The computer used to run SNMP management software (e.g., HP AdvanceStack Assistant). It is used

by the network manager to monitor the network and devices on the network.

Out-of-Band

A way of communicating with a network device from outside the standard network channels via the

serial port.

RJ-45 Connector

Most common terminator for twisted-pair wiring.

SLIP (Serial Line Internet Protocol)

Internet protocol used to transfer IP datagrams over serial lines.
