Automatic Shutdown Of The Equipment; Automatic Shutdown When Detecting Fan Failure; Automatic Shutdown When Detecting Abnormally High Temperature - Hitachi HF-W6500 45/40 Feature Manual

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".
• After an automatic shutdown initiated by this function is complete, the power is turned
off.
• A user application can also shut down the equipment using a RAS event that notifies that
fan failure is detected. For information about a RAS event, see "4.2 RAS Event
Notification".
NOTE
• 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. Enable this function whenever you can.
• Even if you do not use this function, use a RAS event that notifies that fan
failure is detected, and shut down the equipment from a user application.
• For information about how to replace a fan, refer to "HF-W6500 Model 45/40
INSTRUCTION MANUAL (manual number WIN-62-0064)".

5.1.2 Automatic shutdown when detecting abnormally high temperature

When the temperature sensor in this equipment detects the temperature is abnormally high
inside the chassis, the equipment automatically shuts down.
• This function can be enabled or disabled in the RAS Setup window. In the default
factory setting, this function is disabled. 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.
• A user application can also shut down the equipment by using a RAS event that notifies
that abnormally high temperature is detected. For information about a RAS event, see
"4.2 RAS Event Notification".
