Fan mode behavior
CAUTION: To avoid damage to server components, fan blanks must be installed in fan bays 1 and 2 in
a single-processor configuration.
CAUTION: To avoid damage to the equipment, do not operate the server for extended periods of time if
the server does not have the optimal number of fans installed. Although the server might boot, do not
operate the server without the required fans installed and operating.
Valid fan configurations are listed in the following table.
1 processor 24-
SFF or 12-LFF
configuration with
high-performance
fans
For a single-processor configuration, excluding 24-SFF and 12-LFF configurations, 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.
For a dual-processor configuration or single-processor 24-SFF or 12-LFF configurations, 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.
High-performance fans might be necessary in 24-SFF and 12-LFF configurations for the following
installations:
• Optional GPU riser installations
• ASHRAE compliant configurations
