HP ProLiant DL560 Server - Manual (Page 69)

Hardware Options Installation 69
− The BIOS suspends the server for 5 minutes if a cautionary temperature
level is detected. 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.
− In a nonredundant configuration, the BIOS performs an orderly
shutdown if a fan failure occurs in the processor zone or power supply
zone. In a redundant configuration, the BIOS performs an orderly
shutdown if two fan failures occur in the processor zone or power supply
zone.
− The server performs an immediate shutdown if a critical temperature
level is detected.
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 a cautionary
temperature level is detected. If the server detects a critical temperature
level before the orderly shutdown occurs, the server performs an
immediate shutdown. Additionally, in a nonredundant configuration, the
Health Driver performs an orderly shutdown if a fan failure occurs in the
processor zone or power supply zone. In a redundant configuration, the
Health Driver performs an orderly shutdown if two fan failures occur in
the processor zone or power supply zone.
− With the Health Driver loaded and Thermal Shutdown disabled in
RBSU, the server performs an immediate shutdown if a critical
temperature level is detected. The Health Driver will not initiate an
orderly shutdown if a cautionary temperature level is detected.
− Without the Health Driver loaded, the server performs an immediate
shutdown if a critical temperature level is detected.
IMPORTANT: An immediate shutdown is a hardware-controlled
function and it overrides any firmware or software actions.
