Figure 6-11. System Fans
Replacing System Fans
1. Use IPMI to determine which fan has failed, or open the chassis cover to
determine visually.
2. Turn off the system power and remove the chassis cover.
3. Unplug the fan wiring from the serverboard.
6-6 Cooling Systems
The chassis contains four 8-cm high-performance fans and an air shroud to direct
air flow.
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.
