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
