What Is the FEIP?

Depending on the type of media you use between the MII connection on the port adapter and your switch or hub, the network side of your 100BASE-T transceiver should be appropriately equipped with SC-type or ST-type connectors (for optical fiber), BNC connectors, and so forth. Figure 17 shows the pin orientation of the female MII connector on the port adapter.

The MII receptacle uses 2-56 screw-type locks, called jackscrews (shown in Figure 17), to secure the cable or transceiver to the MII port. MII cables and transceivers have knurled thumbscrews (screws you can tighten with your fingers) that you fasten to the jackscrews on the FEIP MII connector. Use the jackscrews to provide strain relief for your MII cable. (The RJ-45 modular plug has strain relief functionality incorporated into the design of its standard plastic connector.) Figure 17 shows the MII connector.
