6 Fan Module
The redundant fan module ensures cooling of the PRIMERGY S60 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 of the storage subsystem (see section “Meaning of the S60 Operating Status LEDs” on page 16) and on the fan LED (see section “Fan LED” on page 23).
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.
