Replacing a System Fan
Fan speed is controlled by system temperature, as monitored by the RAIDiator firmware. If a fan
fails, the remaining fans will ramp up to full speed, the overheat/fan fail LED on the control panel

your earliest convenience. Remove the top chassis cover while the system is still running to
determine which of the fans has failed.

system is operating to assure proper cooling. Out of warranty damage to the
system can occur if this practice is not strictly followed.
