• The BIOS suspends the server for 5 minutes if it detects a cautionary temperature level. If the
cautionary temperature level is still detected after 5 minutes, the BIOS performs an orderly
shutdown and then restarts. This process repeats until the cautionary temperature level is no
longer detected.
• The BIOS performs an orderly shutdown if the following minimum requirements are not met: a
minimum of five fans in the standard configuration or seven fans in the redundant configuration.
• The server performs an immediate shutdown if it detects a critical temperature level.
IMPORTANT: An immediate shutdown is a hardware-controlled function and it overrides any firmware or
software actions.
• In the operating system:
• With the Health Driver loaded and Thermal Shutdown enabled in RBSU, the Health Driver
performs an orderly shutdown if it detects a cautionary temperature level. If the server detects a
critical temperature level before the orderly shutdown occurs, the server performs an immediate
shutdown. Additionally, the Health Driver performs an orderly shutdown if the following minimum
requirements are not met: a minimum of five fans in the standard configuration or seven fans in
the redundant configuration.
• With the Health Driver loaded and Thermal Shutdown disabled in RBSU, the server performs an
immediate shutdown if it detects a critical temperature level.
• Without the Health Driver loaded, the server performs an immediate shutdown if it detects a
critical temperature level.
IMPORTANT: An immediate shutdown is a hardware-controlled function and it overrides any firmware or
