Diagnostic information is stored in flash to support the hardware
configuration, both at time of manufacture and in the field. This
includes recording the initial configuration changes to hardware and
software, and various environmental statistics helpful in determining
why failures are occurring in the field. The flash is provided for
storage of critical data that must remain in the unit after power to the
unit is lost. The data in the flash is used for diagnostic information
for a catastrophic failure, or over the phone with a customer.
