Overheat/Fan Fail: When this LED fl ashes it indicates a fan failure. When on continuously (on and not fl ashing) it indicates an overheat condition, which may be caused by cables obstructing the airfl ow 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 (see Chapter 5). This LED will remain fl ashing or on as long as the overheat condition exists.
