Chapter 6: Advanced Chassis Setup

6-3

6-3 System Fans

Three 8-cm fans provide all the cooling needed for the Series3800/SR120R-2

(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 ﬂ ash. 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 (p/n FAN-0070). Position

the new fan at its proper place in the chassis by ﬁ tting 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.
