Parameter

Tips "Fan Failure Policy" is factory set to "Allow Operation with Critical Fan
Failures."

If NEC ESMPRO ServerAgentService is installed, set "Thermal Shutdown" to
"Disabled" because shutdown at high temperature is executed by NEC
ESMPRO ServerAgentService.
Express5800/R120h-1E, R120h-2E Maintenance Guide
Description
Use this option to select the fan cooling solution for
the system. Optimal Cooling provides the most
efficient solution by configuring fan speeds to the
minimum required speed to provide adequate
cooling. Increased Cooling runs fans at higher
speeds to provide additional cooling. Select
Increased Cooling when third-party storage
controllers are cabled to the embedded hard drive
cage, or if the system is experiencing thermal issues
that cannot be resolved. Maximum cooling provides
the maximum cooling available on this platform.
Use this option to control the reaction of the system
to caution level thermal events. When disabled, the
System Management Firmware ignores thermal
events, and the system immediately powers off in
data-destructive situations.
With this function, you can set the correspondence
method of the system when the fan required for the
system configuration is removed. When configured
for Enable Messaging, the server displays messages
and log events to the Integrated Management Log
(IML) when required fans are not installed. The
server can still boot and operate. When configured
for Disable Messaging, the server does not display
messages and log events when required fans are not
installed. Not all information will be notified. It is
recommended that you leave Fan Installation
Requirements in the default state of Enable
Messaging. Operating without the required fans can
result in damage to hardware components.
With this function, the correspondence method of the
system can be set when a fan failure occurs. If
"Shutdown/Halt on Critical Fan Failures" is set, the
system will be shut down when the fan configuration
required for the system is no longer available. If
"Allow Operation with Critical Fan Failures" is set, the
system can continue operation without the fan
configuration required for the system.
Use this option to enable the server to operate at
higher ambient temperatures
supported. These options are only supported with
specific hardware configurations. See your server
documentation before configuring the server to
enable extended ambient temperature support.
Improper system operation or damage to hardware
components can result from enabling these options in
unsupported configurations. Selecting Enabled for
40c Ambient (ASHRAE 3) enables the server to
operate in environments with ambient temperatures
up to 40 degrees Celsius. Selecting Enabled for 45c
Ambient (ASHRAE 4) enables the server to operate
in environments with ambient temperatures up to 45
degrees Celsius. Not all servers support both 40c
Ambient (ASHRAE 3) and 45c Ambient (ASHRAE 4).
