Component identification 27
CAUTION:
To avoid damage to server components, a fan or fan blank must always be installed
in fan bay 1.
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, HP does not recommend operating the server without the required fans installed and
operating.

For a single-processor redundant configuration, six fans and one blank is required in specific fan bays for
redundancy. A fan failure causes a loss of redundancy. A second fan failure 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 redundant configuration, all fans are required for redundancy. A fan failure causes a
loss of redundancy. A second fan failure 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:
