All complex devices have some way to tell the person who will eventually have to fix the device an idea of what is wrong. Cars, when hooked up to diagnostic computers, emit codes to signal problems. PCs use the BIOS to emit different sequences of beeps and screen messages when the system cannot boot up. Heck, even your alarm clock flashes "12:00" when there is an error (ie. no time is set). The XBOX 360 takes advantage of the front LEDs to indicate errors that occur before the TV image can be displayed. They are probably all kinds of Red, Orange and Green "ring" combinations to signal different problems be it CPU, drive, memory, fan, etc... It would be unfair to accuse Microsoft of having anticipated this error, because they have anticipated every single error!
