System Cooling
Six hot-swap, heavy-duty rear mounted fans provide cooling. They can be replaced without
powering down the system.
Fan speed is controlled by a system temperature setting in IPMI. If a fan fails, the remaining
fans will ramp up to full speed. Replace any failed fan at your earliest convenience with the
same type and model. The system can continue to run with a failed fan.
Replacing a System Fan
1. While the power is running, examine the fans to determine which fan has failed.
2. On the failed fan, simultaneously squeeze the fan's side release tabs inward.
