3.8 System Cooling
The SuperServer SYS-E403-12P-FN2T includes three replaceable 8-cm x 3.8-cm fans and
one air shroud to direct air flow. Make sure the chassis top cover makes a good seal so the
cooling air circulates properly through the chassis.
Caution
: Since the system continues to draw a small amount of power in standby mode (and
fans are off), there is a potential for overheating if the system is idle for a long time. In this
situation, there is no warning from the overheat/fan fail LED.
Fans
Three 8-cm x 3.8-cm fans provide the cooling for the system. These fans circulate air through
the chassis as a means of lowering the chassis internal temperature. 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.

Replacing Fans
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. Replace any failed fan at your earliest convenience with
the same type and model.
1. Power down the system and remove the AC power cord and the chassis cover.
2. Remove the old fan from the fan brace by pressing the fan latch and pulling it up.
