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 XL-GPS System Status Group
Note
: For the figures in this chapter, substitute “xlgps” for “xli”.
The XL-GPS 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
the reference clock source. The systemStatusGeneralGroup also contains the statusDescriptorStr object
that returns a text string identical to the output of the F73 command on the command line interface. The
systemStatusDetail
group contains objects describing the current status of each system object. See the
graph above and refer to the xlGpsSystem-SMIv2.mib MIB for a complete description of each object.
