GRP MII Ethernet Connections

The GRP MII Ethernet connection requires an external physical sublayer (PHY)
and an external transceiver that permits connection to multimode fiber for
100BASE-FX or 100BASE-T4 physical media. Depending on the type of media
between the MII receptacle and the switch or hub, the network side of your
100-Mbps transceiver should be appropriately equipped with fiber-optic SC-type
or ST-type connectors, coaxial cable BNC connectors, or other appropriate
hardware.
Figure 2-18 shows the pin orientation of the female MII connector on the GRP.
The MII connector uses 2-56 screw-type locks, called jackscrews, to secure the
cable or transceiver to the MII port. MII cables and transceivers have knurled
thumbscrews that you fasten to the jackscrews on the MII connector to provide
strain relief for your MII cable.
