System Cooling; System Fans - Supermicro SuperServer SYS-110A-16C-RN10SP User Manual

System Cooling

The SuperServer SYS-110A-16C/24C-RN10SP is cooled by up to three fans and an air
shroud.

System Fans

The fans can adjust their speed according to the heat level sensed in the system, which
results in more efficient and quieter fan operation. Fan speed is controlled by IPMI. Each fan
has its own separate tachometer.
If a fan fails, the remaining fans will ramp up to full speed, the overheat/fan fail LED on the
control panel will blink on and off, and an alarm will sound. Replace any failed fan at your
earliest convenience with the same type and model.
Replacing a System Fan
1. Determine which fan has failed using remote management.
2. Once the failed fan has been identified, remove power from the system as described in
Section 3.1.
3. Remove the chassis cover as described in Section 3.2.
4. Disconnect the failed fan from the motherboard.
