Overheat/Fan Fail:

When this LED flashes, it indicates a fan failure. When on continuously it indicates
an overheat condition, which may be caused by cables obstructing the airflow 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 flashing or on as long as the indicated condition exists.
