4-8 Operation
GX2-LM1000E* Installation and Operation Manual
Network Management
The GX2-LM1000E* monitors selected parameters during operation and compares the
measurements to a table stored in NVM. This table defines high and low limits, as well as the
STATUS LED indication if a fault occurs. When a measurement exceeds the alarm limit, the
STATUS LED displays the appropriate color and the fault is reported to the GX2-CM100B. You
can use the network management system to further isolate fault conditions.
Table 4-1 identifies the default alarm limits and describes the STATUS LED indication for given
parameters:
