Fast Ethernet Connector Signals

The two connectors on the FEIP are a single MII, 40-pin, D-shell type, and a single RJ-45. You can
use either one or the other. Only one connector can be used at one time. Each connection supports
IEEE 802.3u interfaces compliant with the 100BaseX and 100BaseT standards. The RJ-45
connection does not require an external transceiver; however, the MII connection does.
The RJ-45 modular connector has strain relief functionality incorporated into the design of its
standard plastic connector. Table A-4 and Table A-5 list the pinouts and signals for the RJ-45 and
MII connectors.
