Reset
The reset switch is a small pushbutton switch located on the bottom
circuit board between the Power and Transmit Condition indicators
(Figure 2). Pressing this switch will reset the multiplexer. If this fails
to clear a problem, disconnect power from the unit for five seconds and
then reconnect.

Indicators
There are five indicators visible on the front panel. These indicators
provide information about the multiplexer's operation. You should
become familiar with which lights are on during normal operation. If
this pattern changes, there may be a problem.
The indicators and their function are:
POWER
ON when power is applied to the unit.
TRANSMIT CONDITION
ON when there is activity on the network.
OFF means the network is down.
RECEIVE ERROR
Flashes when a data error is detected.
MULTIPLEXING
Flashes rapidly when the multiplexer is on-line.
OFF means this drop is not active.
TEST
Flashes when drop polling has been killed or suspended for
troubleshooting.
