Cabling specifications, distance limits, and other topology rules must be followed in order to avoid collisions, data loss, and downed network connections. The 10/100 Hub is equipped with RJ-45 ports that can automatically adjust to either 10Mbps or 100Mbps speeds. Each port can operate at either speed, completely independent of the other ports' speeds, and can be connected to a workstation, file server, print server, hub, or another node with twisted-pair cabling. Although there are different grades of cabling, you must use EIA 568 Category 5 unshielded twisted-pair (UTP), or better, for each connection you make, and each cable should not exceed 100 meters, (328 feet), in length. Category 5 cabling can be obtained at most computer stores, or you can crimp your own. See page 8 for cabling specifications. Here are some important cabling rules to follow: · Computers should never be connected directly together on a network. They should always be connected to a hub. · Only two 100Mbps Fast Ethernet hubs can be cascaded, (or uplinked), together. To cascade more than 2 100Mbps hubs, a switch or a repeater must be used. · The maximum length for a Category 5 cable between a 100BaseTX or 10BaseT workstation and a hub is 100 meters (328 feet). · The maximum distance between 2 100BaseTX hubs without a switch is 5 meters (16.4 feet). · The maximum distance between 2 10BaseT hubs, (or a 10BaseT hub and an Auto-Sensing hub), is 100 meters (328 feet). 3
