II. System Components Circulation System The server's air circulation system is comprised of five 3 inch (8 cm) fans mounted on a metal fan module. The circulation system cools the hard disk drives by bringing fresh air in from the front and forcing the hot air out through the back. It is important to keep the air surrounding the hard disk drives below 122˚F (50˚C) to prevent hard disk failures. Fan Replacement The fan module can be removed by pulling the handle and inserted by pushing. The handle must be in the out position to insert the fan module. The individual fans are secured by two clips and two hooks. To release these clips, use a screw driver to push these clips in and then slide the fan out. If an individual fan fails, remove the fan and send it back to the vendor for replacement. If all five fans fail, it may be that the fan control board needs replacing, remove the control board and send it back to your vendor for replacement.
