5. CONTROLLING THE HARDWARE

5.1 Automatic Shutdown 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. The equipment can be also
automatically shut down by a remote shutdown signal input from an external device.

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".
• 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 after a fan failure is detected, internal
parts such as processors will not be cooled sufficiently. In such a case,
equipment malfunctions might occur, causing erratic system operation or
damage to components. 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-W7500 Model 65/60
INSTRUCTION MANUAL (manual number WIN-62-0075)".
