The 10/100 module is compatible with the IEEE 802.3 10BaseT standard and the
IEEE 802.3u 100BaseT standard. The ports use RJ-45 connectors and Category 5
unshielded twisted-pair (UTP) copper cabling. For connector and schematic
information, see Appendix B, "Connectors and Cables."
The 100BaseFX modules have either two or four switched 100BaseFX ports for
