Troubleshooting
Alarms
The following table lists common NAV alarms shown on the
Monitoring
page (see Alarms
pane on page 49) and suggested remedies:
Alarm Cause Remedy
Assignment Conflict The endpoint is reporting a conflicting
assignment status. Verify that the endpoint is not assigned
to another NAVigator. If it is, it must be
unassigned from the previous NAVigator.
If the previous NAVigator is unavailable,
perform a
mode 5 reset (see page 16)
on the conflicted endpoint.
Assignment Failure
The endpoint failed to be assigned to a
NAVigator. Confirm that the NAVigator has not
reached its endpoint assignment limit.
If a device has been decomissioned
from the NAV system, unassign the
endpoint from the "Offline endpoints"
list. If endpoint still cannot be assigned,
perform a
mode 5 reset
on the
endpoint.
Audio Loss The input audio signal level is below
-60 dB for a period of 5 minutes or more. Increase the output level of audio source.
Auth Failures A user has attempted to login
unsuccessfully 10 or more times. Check whether login attempts were from
internal personnel. If not, take action to
strengthen security measures.
Backup Restore Failure A problem occurred while trying to
perform a backup or a restore. Debug network connectivity between the
NAVigator and endpoints.
Channel Conflict Two or more NAV devices on the
network have been given the same input
or output number. For devices affected, change the input
number or output number so that each
is unique to decoders in the system.
Communication Failure
An online assigned endpoint cannot
establish a connection with the
NAVigator. Check the network settings to ensure
unicast routing is possible between the
NAVigator and endpoints.
Controller Disconnect The NAV device is unable to connect to
a paired control processor. Verify the control processor is online.
Review network settings to ensure
unicast communication is possible from
the NAV device to the control processor.
CPU Usage The NAV device CPU is overloaded. Check for excessive network data being
delivered to the endpoint.
Device Offline An assigned NAVigator is not discovered
on the network. Check the offline NAVigator for a power
failure. Check the network connectivity of
the endpoint.
