System Cooling
Replacing a System Fan
Fan speed is controlled by system temperature via IPMI. If a fan fails, the remaining fan will
ramp up to full speed and the overheat/fan fail LED on the control panel will turn on. Replace
any failed fan at your earliest convenience with the same type and model (the system can
continue to run with a failed fan).
Remove the top chassis cover while the system is still running to determine which of the fans
has failed. Then power down the system before replacing a fan. Removing the power cord(s)
is also recommended as a safety precaution.
