9.2 Radio
9.2.1 No Activity
If communication over the radio link has been lost and the unit at the other end of the link can
be managed on its local network, the following procedure should be adopted:
If there is no wireless activity then the configuration should be checked. It is essential that the
following items are correct
• Check for Alarm conditions on Home page
• Check that the software at each end of the link is the same version
• Check that the Target Mac address has not been mis-configured at each end of the link.
• Check
Range
• Check Tx Power
• Check License key
• Check Master Slave
• Check that the link has not been further obscured or the ODU misaligned.
• Check the Spectrum Management page at each end of the link and establish that there is
a quiet wireless channel to use.
If there are no faults found in the configuration and there is absolutely no wireless signal retry
the installation procedure. If this doesn’t work then the ODU may be faulty.
9.2.2 Some Activity
If there is some activity but the link is unreliable or doesn’t achieve the data rates required
then
• Check that the interference has not increased using the DFS measurements
• If a quieter channel is available check that it is not barred
• Check that the path loss is low enough for the communication rates required
• Check that the ODU has not become misaligned
• Check that one or both ends of the link are not in installation mode (ARMED)
