Chapter 1 General Description
●
When the rack conversion kit is installed
The server supports changing of the rotational speed of cooling fans. Cooling fans rotate at the minimum
rotational speed until the temperature rises, and the server becomes necessary to be cooled by raising the
cooling fan speed. The server shuts down in the following cases related to temperature:
●
If temperature in caution level is detected, iLO 5 performs a normal shutdown at POST execution and OS.
If the server hardware detects temperature in critical level before a normal shutdown, the server performs
an immediate shutdown.
●
If Thermanl Shutdown function is set to Disabled in BIOS/Platform Configuration (RBSU), iLO 5 does not
perform a normal shutdown even if a caution temperature level is detected. Even if this feature is disabled,
the server hardware performs an immediate shutdown when a critical temperature level is detected.

Important
If Thermal Shutdown function is set to Disabled in BIOS/Platform
Configuration (RBSU), high temperature events may damage server
components.
