HP ProLiant DL388p User Manual page 20

For a single-processor configuration, four fans and two blanks are required in specific fan bays for
redundancy. A fan failure or missing fan causes a loss of redundancy. A second fan failure or missing fan
causes an orderly shutdown of the server.
Installing more than the required number of fans in a single-processor configuration is not a supported
configuration.
For a dual-processor configuration, six fans are required for redundancy. A fan failure or missing fan causes
a loss of redundancy. A second fan failure or missing fan 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 during 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.
