Attach to alternate media types via the Class I MII port
Limits on total network span also apply to MII port
5.Connect other media types using the D-type MII port.
You can also connect to other network devices using the media independent interface (MII) on the back panel. You can attach to 100BASE-TX (operating at 100 Mbps only), 100BASE-T4 or 100BASE-FX media types by plugging the appropriate transceiver into the MII connector. This port can be used to connect the hub to a collapsed backbone, or for media conversion to a compatible network device. However, note that the MII Port is Class I, and therefore cannot be cascaded to another hub.
When connecting a switch or router to the MII port with twisted-pair cable, the maximum network span is 200 meters or 656 feet (i.e., 100 meters for the downlink from the switch or router to the hub, and 100 meters from hub to workstation). However, by attaching fiber-optic cable to the MII port on the rear panel, the maximum network span can be extended to 260 meters or 853 feet (i.e., 160 meters for the fiber optic downlink from the hub to the switch or router, and 100 meters from hub to workstation).
6.These hubs can serve as a collapsed backbone for small networks, or can be connected to a network interconnection device via one of the RJ-45 ports or the MII port. (Refer to Chapter 3 for sample applications.)
7.Verify network communications by ensuring that:
∙you have made all the necessary connections
∙you can access any connected resources
∙the hub’s indicators are functioning properly
If you encounter any problems installing this dual-speed CheetaHub, refer to Chapter 2 for a detailed description of installation procedures, Chapter 3 for sample configurations, or Appendix A for help in troubleshooting.
