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 tem-
perature 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.
