State Sensor Alarm Conditions
The gateway has many sensors that check the state of a voltage, component, or
system fault, or voltage presence. In an acceptable state, the state sensors report a
value of
State Deasserted
, meaning no error. When a voltage, component, or
system goes to a detrimental state, the state sensors report a value of
State
Asserted
.
For example, when the state of sensor target
/SYS/FAN1/FAULT
is
State
Asserted
, there is a problem with fan 1.
