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 push-
ing. 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 replace-
ment. 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.
When replacing fans, be sure
that the fan rotations are in the
same direction. Use the
manufacturer’s sticker on one
side of the fan as a reference as
to the side. Air flows from the
front of the server to the rear.
