4. Check the cable resistance between pins 4 & 7 at the RJ45. Check against column 4 in
Table 20.
5. Ensure that there is greater than 100K ohms between pins 1 & 8 for all cable lengths.
6. Ensure that there is greater than 100K ohms between pin 1 and ODU ground for all cable
lengths.
7. Ensure that there is greater than 100K ohms between pin 8 and ODU ground for all cable
lengths

10.2 Radio

10.2.1 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 misconfigured at each end of the link
Check Tx Power
Check License keys to ensure that both units are the same product variant
Check Master/Slave status for each unit and ensure that one unit is Master and the other unit
is slave
Check that the link has not been further obscured or the ODU misaligned
Check the DFS 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.

10.2.2 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 i-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
