Overheat/Fan Fail: When this LED ashes it indicates a fan failure. When continu-
ously 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.
Power Failure: When this LED ashes, it indicates a failure in the redundant power
supply.
