Chapter 3 Installing the Cisco 7206 Connecting I/O Controller Cables Fast Ethernet MII Connection Equipment The MII port on the I/O controller is a 40-pin, D-shell type connector that is configurable for 100 megabits per second (Mbps) full-duplex or half-duplex (half-duplex is the default). The MII port supports IEEE 802.3u interfaces compliant with the 100BASEX and 100BASET standards. The MII connection requires an external transceiver that permits connection to multimode fiber for 100BASEFX or 100BASET4 physical media (refer to Figure 3-15).

Figure 3-16 shows the pin orientation of the MII port on the I/O controller. The MII port uses two 56 screw-type locks, called jackscrews, to secure the cable or transceiver to the port. MII cables and transceivers have knurled thumbscrews that you fasten to the jackscrews on the MII connector and tighten with your fingers. Use the jackscrews to secure your MII cable to the MII port.
