Meaning
Activated when the OS is
shut down (standby or the
main power is off) or when
power is not supplied to the
equipment.
Activated when the OS,
application, device driver, or
the like cannot run properly
due to an abnormally high
system load or has crashed.
This is a maintenance request
signal. This contact is
activated when the
temperature, the fan status or
one side of mirrored
disks (B model, T model
only)
is abnormal.
These are general-purpose
contact output signals. A user
can assign a function to each
one of the contacts GENDO0
through GENDO2.
Activated when a timeout is
detected by the watchdog
timer. A timeout is also
detected when the OS is shut
down (standby or the main
power is off) or when power
is not supplied to the
equipment.
