•Using the RESET Button (Section4.3)

4.1 USING LANVIEW

The modules use a built-in visual diagnostic and status monitoring system called LANVIEW. The
LANVIEW LEDs (Figure 4-1) allow quick observation of the network status to aid in diagnosing
network problems.
Viewing Receive and Transmit Activity
Only one group of segments may be viewed at a time.
To view the receive and transmit activity on a group of segments, press the GROUP SELECT
button (see Figure4-1) to step to the group of interest (Groups 1 through 4). Each time the GROUP
SELECT button is pressed, the GROUP LED lights up in sequence, indicating which Group is
selected. The receive and transmit activity for that group of segments is then indicated by the RX
and TX LEDs for each segment.
Fast Ethernet Speed LED
This LED indicates whether the port is in 10Mbps or 100 Mbps Ethernet. When the LED is off,
the port is functioning at 10Mbps. When the LED is on solid green, the speed is 100 Mbps.
