Amber — A fault has been detected or a service action is required.
Blinking amber — Hardware-controlled power-up or a cache flush or restore
error.
Green — Cache contains unwritten data and operation is normal. The
unwritten information can be log or debug data that remains in the cache, so
a Green cache status LED does not, by itself, indicate that any user data is at
risk or that any action is necessary.
Off — In a working controller, cache is clean (contains no unwritten data).
This is an occasional condition that occurs while the system is booting.
Blinking green — A CompactFlash flush or cache self-refresh is in progress,
indicating cache activity.
