3.7 System Cooling
Three heavy-duty hot-pluggable fans (p/n FAN-0206L4) provide cooling for the chassis. Fan
speed is controlled by system temperature via BMC. If a fan fails, the remaining fans 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). Use remote management to determine which of the fans has failed.

2. Press the tabs on the sides of the fan to unlock and remove the fan and its housing. The

Installing a New Fan

2. Insert the new fan and listen for a "click".
3. If the system power is on, the hot-plug feature will cause the fan to start immediately upon
being connected to its header on the serverboard.
