Description
Device has been reset
AlResFlag
Reports that the main-controller
has had a reset. This can
indicate that all the parameters
in the device are changed.
Self test
AlSelfTest
After power-on or reset, the
device performs an internal self
test. If this self test fails it will
trigger this alarm.
Incompatibility
AlIncompat
The device asserts the
incompatibility alarm if a new
control setting was attempted
that would result in a conflict with
one or more of the other present
settings. The new control setting
is accepted but not activated (the
device remains operational in the
last state).
By changing one or more of the
conflicting parameters, the
incompatibility condition can be
removed. Only when this occurs,
the new "compatible" state is
activated and the incompatibility
alarm is de-asserted.
Under RMCP, details on the type
of incompatibility that occurred
can be obtained using the
"Incompatibility Identification"
command.
