Operations 30
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 all fans to spin at high speed. 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 thermally
supported configuration.
For a dual-processor configuration, six fans are required for redundancy. A fan failure or missing fan
causes all fans to spin at high speed. A second fan failure or missing fan causes an orderly shutdown of
the server.
The server supports variable fan speed. 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, iLO 3 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, iLO 3 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.
