• The Data Port of either CMU is not connected or has not negotiated at 1000 Mbps.
Check that there is no outstanding Rx Diversity Data Port Status alarm on either CMU.
• If none of the above conditions exist but Rx Diversity Availability is still indicating a
problem, the likely cause is the configuration of the Rx Diversity VLAN in the Ethernet
Switch. Check that the Ethernet Switch is configured correctly to ensure that Rx
Diversity Ethernet Frames are bridged between the Inactive and Active.
Rx Diversity Data Port Status
Definition: For Rx Diversity to operate, the Data Port of both the Active and Inactive CMU
must be negotiated at 1000 Mbps. This attribute is displayed if this is not the case.
Cause and action:
• There is a problem with the Ethernet Cable. Check that the Data Port Status of both
neighbor CMUs is indicating that the port has negotiated at 1000 Mbps Full Duplex.
• The Active or Inactive CMU has been configured to prevent operation at 1000 Mbps.
Check that the Data Port Copper Auto Negotiation is set to enabled and that Data Port
Copper Auto Neg Advertisement includes 1000 Mbps Full Duplex. These are available
on the LAN Configuration page.
• The Ethernet Switch is configured to prevent operation at 1000 Mbps.
• If operating with Fiber-Y,the Data Port of the Inactive CMU has trained with fiber. This
is incorrect for Fiber-Y. Check that the value of Data Port Status is set to Copper Link
Up. This is displayed on the Status Page. If this is not the case, check that copper Data
Port is also connected to the Ethernet Switch as well as the Fiber-Y cable.
SNTP Synchronization Failed
Definition: SNTP has been enabled but the unit is unable to synchronize with the
specified SNTP server.
Cause and action: If SNTP Sync fails then check the server settings or disable SNTP and
set the time locally. See Setting the real-time clock on page 6-115.
Unit Out Of Calibration
Definition: The unit is out of calibration and must be returned to the factory using the
RMA process for re-calibration.
Cause and action: Check the calibration status and arrange for recalibration of the unit.
Wireless link status
Definition: The status of the end-to-end wireless link.
Cause and action: See Table 254 for values and their meanings.
