Connect the Network Cable
Category 5 UTP cable is good enough to qualify under both the Fast Ethernet cabling
rules and the traditional Ethernet cabling rules. The maximum individual cable run
between any station and its supporting hub or switch is 100m. The maximum individual
cable run joining two hubs is 10m in general, but is 100m when both hubs qualify as
Ethernet Class 2 Repeaters ( all D-Link Ethernet hubs do qualify). But these cable runs
may need to be shorter than the given individual maximum lengths, because their lengths
are also restricted by the rule that the maximum aggregated cable run between any two
stations is 205m.
Connecting for Fast Ethernet
Category 5 UTP cable is required for Fast Ethernet operation. The maximum length of
cable between the DFE-680TXD and the supporting hub is 300 ft. The cable must be
“ straight” (not a“crossover” cable), with an RJ-45 plug at each end. Make the network
connection by plugging one end of the cable into the RJ-45 receptacle of the direct port,
and the other end into a port of the supporting hub.
Connecting for 10Mbps Ethernet
Category 3, Category 4, and Category 5 UTP cable, as well as EIA/TIA - 568 100-ohm
STP cable, all qualify under traditional Ethernet cabling rules. The maximum cable run
between the DFE-680TXD and the supporting hub is 300 ft. The cable must be “straight”
(not a “ crossover” cable) with RJ-45 plug at each end. Make the network connection by
plugging one end of the cable into the RJ-45 receptacle of the direct port, and the other
end into a port of the supporting hub.
