The XLI systemAlarmData group defines SNMP traps and cannot be directly retrieved by the SNMP
manager. When a system alarm event occurs an SNMP trap alarmSystemNotification is sent to the
SNMP managers previously configured to receive traps. Included in the trap message are the variables
contained in the systemAlarmData group: IP address, timestamp, alarm code, and the F73 status string.
The systemFaultConfig sub-group contains parameters to control the generation of system alarms. The
timeout, threshold and power on suppress values are contained in the systemFaultConfigData group.
Also in this group is a method object configDataLatchClear. By setting this object the user clears all
latched faults. Reading the configDataLatchClear object has no effect and its value is not defined. The
systemFaultConfigMasks group contains masks for each possible system alarm event. When the status
changes, for example if the primary GPS becomes unlocked, the associated mask is checked. Only if
the mask is enabled will a system alarm be generated.
The systemFaultHistory group contains latched status indicators for each of the system alarm events. If
a system alarm event goes into fault status, even if this status is transient, then the associated entry in
the systemFaultHistory group will maintain a record of that fault occurrence until the latch is cleared,
using the configDataLatchClear object, resetting all systemFaultHistory entries.
The XLi System Status Group
The XLI systemStatus group is used to provide a current operational view of the system. The
systemStatusGeneralGroup gives on overview of the system status, including the status of the clock and
