4.1Compact Media Converter TP/BNC 50-ohm Front Panel

The LEDs

Each Compact Media Converter TP/BNC features diagnostic LEDs. The following illustration shows the location of the LEDs, and other features, on the Compact Media Converter TP/BNC. The LED functions for the Compact Media Converter TP/BNC are as follows:

TP LNK/ACT	Glows yellow when a twisted pair link is established and flickers when
	data is being received
BNC ACT	Flickers green in normal operation indicating activity on the BNC port
BNC COL	Flickers red in normal operation indicating activity on the BNC segment
POWER	Flickers yellow when the unit is receiving power

4.2 Twisted Pair Crossover/Pass-Through Switch

The twisted pair port on the Compact Media Converter TP/BNC features a push-button switch, located next to the twisted pair connector, for selecting a crossover workstation connection or Pass-Through repeater/hub connection. Select a Pass-Through connection by pressing the push-button IN. A Crossover connection is selected when the push-button is OUT. If uncertain whether a Crossover or Pass-Through connection is needed, set the push- button to the position that makes the TP LNK (link) LED glow.

4.3 BNC Port Termination

The Compact Media Converter TP/BNC features a 2-position, termination switch (TERM) next to the BNC connector that allows a think coaxial segment to be terminated at the port without the use of an external ‘T’ connector/terminator. (See the diagram in the Compact Media Converter TP/BNC 50-ohm Front Panel section.)

If a ‘T’ connector/terminator is used, this switched must be set in the OFF (disabled) position. Otherwise, double termination will result, which will corrupt the signal.
