Control
(11) Automatic shutdown
This feature automatically shutdown the equipment when it detects a fan failure, an abnormal temperature inside
the chassis, or a remote shutdown signal input. Configure the settings shown in (4) RAS Setup window to enable or
disable the automatic shutdown feature.
(12) Shutdown via library functions
You can shutdown the equipment from a user application by using the RAS library.
(13) Startup suppression when serious failures occur
This feature suppresses startup of this equipment to protect the hardware when a failure, such as a fan failure, is
detected during OS startup.
(14) Controlling general-purpose external contacts (HJ-F2050-11 and HJ-F2050-12) and digital LEDs for
status indications
This feature allows users to control the general-purpose external contacts and the digital LEDs for status
indications by using the RAS library.
Four input and three output general-purpose external contacts are available. If you use these contacts, signals can
be input from an external device to this equipment, and signals can be output from this equipment to an external
device.
(15) Controlling general-purpose external contacts (HJ-F2050-13) and digital LEDs for status indications
This feature allows users to control the general-purpose external contacts and the digital LEDs for status
indications by using the RAS library.
Two input and two output general-purpose external contacts are available. If you use these contacts, signals can be
input from an external device to this equipment, and signals can be output from this equipment to an external
device.
Library functions
(16) RAS library interface
This interface offers library functions for recording log information, in addition to the library functions offered by
item (10) under Status checks and items (12) and (14) under Control.
Maintenance/failure analysis
(17) Memory dump collection
This feature records the contents of the system memory in a file (a memory dump file) when the reset switch is
pressed after a failure occurs, for example, after the equipment stops unexpectedly. By analyzing the data in this
memory dump, you can investigate the cause of the failure.
