Some activity

If there is some activity but the link is unreliable or does not achieve the data rates
required, proceed as follows:
1
Use the Channel Status web page to check if a quieter channel is available and is
enabled. Refer to
2
Use the Diagnostics Plotter to check that reported Link Loss is low enough to
allow the communication rates required. Refer to
page 7-21.
3
Check that the ODU has not become misaligned.
4
Use the Retry Histogram to check the number of retries. An excessive number of
retries (>10%) could indicate a problem. Refer to
on page 7-20.
5
Use the Diagnostics Plotter to check reported Receive Power at either end of the
link. Ensure that this matches the predicted value from LINKPlanner. Refer to
Using the diagnostics plotter

by turning the equipment off and on), attempt the following corrective actions:
•
Realign or relocate the antenna.
•
Increase the separation between the affected equipment and antenna.
•
Connect the ODU and PoE power supply into a power outlet on a circuit different from
that to which the receiver is connected.
