CAUTION:
To avoid damage to server components, all fan modules must be installed in fan bays
for any processor configuration.
For all processor configurations, the HP ProLiant DL560 Gen8 Server requires six fan modules for
redundancy. A fan failure causes a loss of cooling redundancy. A second fan failure or a missing fan module
causes an orderly shutdown of the server.
The server supports variable fan speeds. The fans operate at minimum speed until a temperature change
requires a fan speed increase to cool the server.
The server shuts down in the following temperature-related scenarios:
•
At POST and in the OS, HP iLO performs an orderly shutdown if a cautionary temperature level is
detected. If the server hardware detects a critical temperature level before an orderly shutdown occurs,
the server performs an immediate shutdown.
•
When the Thermal Shutdown feature is disabled in RBSU, HP iLO does not perform an orderly shutdown
when a cautionary temperature level is detected. Disabling this feature does not disable the server
hardware from performing an immediate shutdown when a critical temperature level is detected.
CAUTION:
A thermal event can damage server components when the Thermal Shutdown feature
is disabled in RBSU.
IMPORTANT:
firmware or software actions.
An immediate shutdown is a hardware-controlled function and it overrides any
