Fault Management of the RF Gateway 1
The RF Gateway 1 supports automatic detection and user notification of changes in
the system. Changes may be classified as either Events or Alarms. Alarms carry a
state while events are important instances that occur in time and are reported. For
example,
Link Lost and Link OK are two well-defined states and are associated with
an alarm. Events Startup , Configuration Backup , and Second Power Supply Inserted do
not have a state but are important events reported by the system.
System Alarms
System Alarms are conditions with state that occur on the system that the user may
want to be aware of. The RF Gateway 1 provides user notification of changes in
alarm state. These notifications can be via SNMP traps, system log or the front panel
fault LED. System alarms can not be masked or filtered and will always be indicated
on the system.
The default alarms supported by the system are defined in the alarm configuration
area of the database. The default alarm configuration parameters include items such
as alarm label, severity, mask, threshold, and enabled notifications. These
parameters are defaults and are not configurable through the web interface.
While active, the system maintains additional information on each of the alarms
such as alarm originator, state, instance, and other descriptive details including
triggering threshold, actual value, and units. Alarms have two possible state values,
Alarm and Clear. Each alarm has two possible severity levels, Critical or Major. The
supported alarms are described in the following table.
Name Severity Description
Power On Self Test Critical A failure during power on self test has been detected.
GbE Port Link Critical A GbE port has changed state.
UDP Traffic Major Complete loss of UDP traffic has been detected.
Fan Failure Major One of the four chassis fans RPM is measuring below
threshold.
FPGA Temperature Major A FPGA board temperature has exceeded the threshold.
Power Supply
Shutdown Critical A power supply has indicated an imminent shutdown.
DTI Port Link Critical A DTI port has changed state.
Power Supply
Voltage Critical One or more power supply voltages is performing outside of
the acceptable threshold.
Continuity Count
Error Critical MPEG continuity counts have been detected on one or more
elementary streams.
