10/100 Fast Ethernet Switch User’s Guide
Overview

AUI Transceiver Connector
The AUI transceiver connector is a 10Mbps port for connecting a
thin or thick Ethernet segment via a transceiver. Please note that
this connector is logically related to twisted-pair Port 3 so they
cannot be used simultaneously, and the twisted-pair port has
priority over the AUI connector. Also, the AUI port only operates
at half duplex. Pinouts for the AUI connector are listed in
Appendix B.
MII Transceiver Connector
The MII transceiver connector is a 10/100Mbps port for connecting
a fiber optic or additional Fast Ethernet segment via a transceiver.
The MII connector, like ports 1 and 2, can auto-detect the speed of
a device connected and auto-adjust to operate at either 10Mbps or
100Mbps. Pinouts for this connector are listed in Appendix B.
LED Indicators
The 10/100 Fast Ethernet Switch has extensive LED indicators to
facilitate monitoring and troubleshooting. They include a Power
LED, a System Load meter, and Status LEDs for all ports. The
Status LEDs have indicators that report on Link, Duplex, Activity,
Collision, and 100Mbps Operation states. There are also AUI and
MII LED indicators.
