5. CONTROLLING THE HARDWARE
5.1 Automatic Shutdown and System Reset of the Equipment
This function automatically shuts down the equipment when running the equipment would
pose a danger when fan failure or abnormally high temperature is detected. By doing so, you
can protect internal parts such as a processor from thermal degradation and prevent thermal
runaway of the system due to malfunction of this equipment. In addition, you can perform a
system reset on the equipment or generate a memory dump when a watchdog timer timeout in
the equipment is detected.
5.1.1 Automatic shutdown when detecting fan failure
When the equipment detects an error in one of the fans, the equipment automatically shuts
down.
• This function can be enabled or disabled in the RAS Setup window. In the default factory-
shipped setting, this function is enabled. For details, see "3.1.3 Using the RAS Setup
window".
• After an automatic shutdown initiated by this function is complete, the power is turned off.
• Alternatively; a user application can detect a fan failure using a RAS event and shut down
the equipment. For information about a RAS event, see "4.2 RAS Event Notification".
If this equipment continues to operate with fan failure detected, internal parts
such as a processor are not cooled down sufficiently, and that may cause
thermal runaway of the system due to malfunction of the equipment or result in
damage to the parts. If possible, enable the automatic shutdown feature.
If the automatic shutdown feature is not used, have a user application detect a
fan failure using a RAS event and shut down the equipment.
NOTE
For information about how to replace a fan, refer to "HF-BT1000
INSTRUCTION MANUAL (manual number BT-62-0002)".
