The cache flush and self-refresh mechanism is an important data protection feature; essentially four copies
of user data are preserved: one in controller cache and one in CompactFlash of each controller.
The LED becomes solid green during the boot-up process. This indicates the cache is logging all POSTs,
which will be flushed to the CompactFlash the next time the controller shuts down.
Caution: If the Cache Status LED is solid green, the controller should be shut-down from the user
interface so unwritten data can be flushed to the CompactFlash.
