Using LANVIEW Diagnostic LEDs
4-2 Troubleshooting
Viewing the Receive and Transmit Activity
You can view the 7G4280 ‐ 19 receive and transmit port activity on the RX and TX LEDs.
However, only one group of six ports may be viewed at a time.
To view the receive and transmit activity on a group of 7G4280 ‐ 19 segments, press the
GROUP SELECT button (see Figure 4 ‐ 1 ) for less than one second to step to the group of
interest (Groups 1 through 3). Each time the GROUP SELECT button is pressed for less
than one second, 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 port.
Figure 4-1 LANVIEW LEDs
Table 4 ‐ 1 describes the LED indications and provides recommended actions as
appropriate.
