3.6.1.10 Frame Squishing
The frame squishing alarm is not likely to be cleared without a service call to On-Ramp Wireless.
If this alarm is detected, call On-Ramp Wireless.
3.6.1.11 EMS DB Backlog
This alarm is set when the time difference between the EMS last queued raw message and the
last inserted messages grow larger than some configured value (default 5 minutes). This alarm
typically will require DBA related actions, such as purging or partitioning database tables.
If the DBA cannot clear the alarm, schedule an On-Ramp Wireless service call.
3.6.1.12 Interference
The interference alarm is not likely to be cleared without a service call to On-Ramp Wireless. If
this alarm is detected, call On-Ramp Wireless.
3.6.1.13 Node Join Failure
This alarm would typically be generated if an end device was trying to join the network, but it
was not previously provisioned and added to the EMS. To fix the problem, add the node through
the EMS, and configure the UI according to the procedures in this document.
If the device has been added to the network, there may be a security key mismatch. See the
KMS documentation, and make sure that security keys have been imported. Additionally, the
operator may need to debug the KMS, EMS, and GW IP connectivity to make sure there are no
issues with the TCP/IP connectivity between these elements.
If the problem persists, call On-Ramp Wireless.
3.6.1.14 TX Suppression
The TX Suppression alarm is not likely to be cleared without a service call to On-Ramp Wireless.
If this alarm is detected, call On-Ramp Wireless.
3.6.1.15 AP Proximity Fault
This alarm is generated by an AP lid being opened. The opening of the AP's lid may be planned
or unplanned. In a planned opening of the AP’s lid, the alarm will be cleared when the service
call is completed. If the operator receives an AP open lid alarm for an unplanned AP service call,
an unauthorized person may be opening the AP’s lid. Appropriate action, per internal policies,
should be taken.
3.6.1.16 AP GPS Fault
This alarm is the result of an AP that loses its ability to get a valid GPS tracking signal. This is
most likely due to a physical problem with either the AP and/or GPS antenna connected to the
AP. This type of alarm would likely be in conjunction with other alarms (for example AP offline)
