Appendix B Connector Pin Assignments

This appendix provides information on the RJ-45 connectors that are used for the Model FE508 and
Model FE516 Fast Ethernet hubs.

RJ-45 Connector

The RJ-45 connector is used to connect stations, hubs, and switches through unshielded twisted-pair
cable and supports 100 Mbps data transmission. The RJ-45 connector accepts two- or four-pair
Category 5 UTP cable. Figure B-1 illustrates the RJ-45 connector used for port connections on hubs.
Table B-1 provides the pin out information for the Normal (MDI-X) RJ-45 connector and the pin out
information for the Uplink (MDI) port (Port 8 on the Model FE508 and Port 16 on the Model FE516)
RJ-45 connector.
