Overheat/Fan Fail
When this LED ashes it indicates a fan failure. When continuously on (not ashing)
it indicates an overheat condition, which may be caused by cables obstructing the
airow in the system or the ambient room temperature being too warm. Check the
routing of the cables and make sure all fans are present and operating normally.
You should also check to make sure that the chassis covers are installed. Finally,
verify that the heatsinks are installed properly. This LED will remain ashing or on
as long as the overheat condition exists.
