A flashing red light which flashes in four second interfals indicates a power
failure.
When notified of an alert, 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 and air shrouds are installed. Finally, verify that the heatsinks are
installed properly. This LED will remain flashing or on as long as the temperature
is too high or a fan does not function properly.
