Chapter 1 General Description
6 fans are needed to enable redundancy for dual processor configuration or 24 x 2.5-inch or 12 x 3.5-inch single
processor configuration. If a fan fails or is missing, redundancy will be disabled.
A high-performance fan is required for the configuration of 24 x 2.5 inch drive model or 12x 3.5 inch drive model.
In addition, it may required for the following installation.
Optional GPU Riser Card
The server controls the cooling fan speed to the optimal value depending on the environment. The cooling fans
rotate at the minimum speed depending on the temperature.
If the factory setting of cooling fans [Optimal Cooling] is selected, the cooling fans may rotate fast when the
server internal temperature increases due to the installation environment or operational status of the server.
If the cooling fans rotate fast and slow repeatedly, change the cooling fan setting to [Increased Cooling] in System
Utilities.

Thermal Configuration
The server executes the specified shutdown under the following temperature control.
●
In case a temperature at a cautious level is detected, iLO5 executes the shutdown of OS safely. In case a
temperature at a critical level is detected, iLO5 executes not a shutdown but a hard shutdown of OS.
●
With "Thermal Shutdown" function set to "Disabled" at "BIOS/Platform Configuration (RBSU)", in case a
temperature at a cautious level is detected, the shut down of OS is not executed and the operation
continues, but in case a temperature at a critical level is detected, a hard shutdown is executed.
Important If “Thermal Shutdown” feature is set to “Disabled” in “BIOS/Platform
Configuration (RBSU),” Server Component may be damaged by a high
temperature event.
Tips
In case NEC ESMPRO ServerAgentService is installed, since a shut down due to
high temperature is executed by NEC ESMPRO ServerAgentService, you need to
set “Thermal Shutdown” to “Disabled.”
