If the single rotor fan (one standard fan) is lost, the redundancy is disabled. If two fan rotors (two standard fans
or one high-performance fan) are lost, the server starts shutting down.
If the PCIe SSD drive is installed to the server, the high-performance fan is used for the configuration of 8x2.5-
type drive + 2x2.5-type PCIe SSD and 10x2.5-type drive.
The server support change of the fan speed. Run the fan at the minimum speed until the temperature rises and
the server must be cooled down by increasing the fan speed. The server shuts down under the following
conditions related to the temperature.

If the temperature at the caution level is detected, iLO 5 shuts down during the POST execution and through
OS in accordance with the normal procedure. If the server hardware detects the temperature at the critical
level before the normal shut-down process starts, the server immediately shuts down.

If the "Thermal Shutdown" function is set to "Disabled" in "BIOS/Platform Configuration (RBSU)" the iLO 5
does not shut down in accordance with the normal procedure while the temperature at the caution level is
detected.
Even if this function is set to "Disabled", the server hardware immediately shuts down when the temperature
at the critical level is detected.

To avoid damaging the server parts, the fan blank cover must be installed to the positions
of fan 1 and fan 2 in the x1CPU configuration.
To avoid damaging the device, do not run the server over a long period of time if the optimal
number of fans are not installed. Although the server may starts up, do not start up the
server while the required fans are installed but not operated.

If the high-temperature shutdown function is disabled in the system utility, heat may damage
the device parts.
If ESMPRO/ServerAgentService is installed, ESMPRO/ServerAgentService executes the

high-temperature shutdown. Therefore, set "Thermal Shutdown" to "Disabled".
