IMC Networks MediaConverter/1 Operation Manual page 8

The switch is labeled with "X" for a crossover connection (factory default) and an "ll"
for a straight-through connection. Select the appropriate setting by moving the switch
to the proper position before installing the media conversion module. If uncertain
whether crossover or straight-through is needed, set the switch to the position that
makes the link LED glow.
Device-Dependent:
The end device connected to the McLIM TX/FX and TX/SX (-20 and -50) determines
the type of twisted pair connection; these McLIM modules do not include AutoCross
or a MDI-II/MDI-X switch.
You must be use the appropriate type of cable to establish a link. Refer to the
connected device documentation for more information.
Twisted Pair Cable Distance
Some McPIM TP/FOs features a 2-position jumper, located at position JP2, for
selecting longer twisted pair cable distances (distances greater than 100 meters).
Place the jumper over both pins for distances up to 100 meters (factory default).
Remove the jumper shunt or place it on only one pin for distances of 100 meters or
more.
The product on the other side of the media conversion must also be able to
support longer cable distances.
Twisted Pair Cable Type
Some McPIM TP/FO modules feature a 2-position jumper, located at position JP3, for
selecting either a shielded or unshielded twisted pair link segment. Remove the
jumper shunt or place it on only one pin to select an unshielded twisted pair link
segment (factory default). Place the jumper shunt over both pins to select a shielded
twisted pair link segment.
