Connecting the Unit
For FX/FXE units, remove the dust cap from the fiber optic connectors and connect the fiber optic cables.
The TX port (located on the bottom connector) on the FX/FXE models should be connected to the RX port of the
far end station. The RX port (located on the top connector) on the FX/FXE versions should be connected to the
TX port of the far end station.
For 10/100 Base-TX ports, plug a Category 5E twisted pair cable into the RJ45 connector. Connect the
other end to the far end station. Verify that the LNK LEDs are ON once the connection has been completed.
To connect any port to another device (end node, Switch or Repeater), use a standard Category 5E straight
through or crossover cable with a
minimum length of one meter and a
maximum length of 100 meters.
N-Tron recommends the use of pre-
manufactured Cat5E cables to ensure the
best performance. If this is not an option
and users must terminate their own ends
on the Cat5E cables; one of the two color
coded standards shown to the right should
be utilized. If a user does not follow one
of these two color code standards then the
performance and maximum cable distance
will be reduced significantly, and may
prevent the switch from establishing a
link.
Warning: Creating a port to port connection on the same switch (i.e. loop) is an illegal operation and
will create a broadcast storm which will crash the network!
