Cascading Hubs Through Utp Cable - D-Link 809TC - Hub - EN User Manual

Cascading Hubs Through UTP
Cable
Any of the UTP ports can be used to cascade hubs together. Note
that when two UTP ports of two hubs are connected together, the
wires inside the UTP cable must be crossed over. See appendix A
for the wire cross-over. Mark all crossed-over UTP cables clearly so
they will not be used by mistake for normal connection.
If you use Mini Hub model DE-809TP, UTP port labeled "9" is
especially designed for hub cascading. When this port is in the
Uplink position, its signal reception and transmission are reversed.
This allows you to dispense with the trouble of crossing the UTP
cable's wires. Putting this port in the Uplink position can be done
by pressing down the button located next to the port.
Note:
Never cause a loop when you cascade hubs since this might
cause unpredictable results.
