Fan Module
The redundant fan module ensures cooling of the PRIMERGY SX30 storage
subsystem. It is equipped with two fans. If one fails, the other working fan suffi-
ciently guarantees cooling and prevents the components of the storage
subsystem from overheating.
A temperature sensor on the rear panel of the power supply unit and a revolution
monitor fitted for each fan are used to permanently check the cooling. Error
messages can be read on the cooling status LED on the front panel of the
storage subsystem (see
section “Meaning of the Operating Status LEDs” on
) and on the fan LED (see
As soon as fan failure is detected, the fan module with the defective fan should
immediately be replaced with an intact module so that the redundancy charac-
teristics (availability) are retained.
