SUPER MICRO Computer 6025B-3R System Fan Failure, Replacing System Fans, Removing a fan

Chapter 6: Advanced Chassis Setup

6-3 System Fans

Three 8-cm fans provide all the cooling needed for the SuperServer 6025B-3/6025B- 3R. It is very important that the chassis top cover is properly installed and making a good seal in order for the cooling air to circulate properly through the chassis and cool the components. See Figure 6-2.

System Fan Failure

Fan speed is controlled by system temperature via a BIOS setting. If a fan fails, the remaining fans will ramp up to full speed and the overheat/fan fail LED on the control panel will flash. 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 (see instructions in Chapter 2) while the system is still running to determine which of the fans has failed.

The hot-plug fan will start to function upon connection to its fan header on the serverboard.

Replacing System Fans

1. Removing a fan

Remove the chassis cover. Press the tabs on the top of the fan housing and remove the fan in its housing (see Figure 6-2). System power does not need to be shut down since the fans are all hot-pluggable.

2. Installing a new fan

Replace the failed fan with an identical 8-cm, 12 volt fan (available from Supermicro, p/n FAN-0070). Position the new fan at its proper place in the chassis by fitting the fan with its housing onto the fan mounts in the chassis. A "click" can be heard if the fan (in its housing) is properly installed. 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.
