Some NVRAM configuration parameters are reset to their defaults. The defaults
include parameters that are more likely to cause problems, such as TTYA settings.
■
These NVRAM settings are only reset to their defaults for this power cycle. If you
do nothing other than reset the system at this point, the values are not
permanently changed.
■
Only settings that you change manually at this point become permanent. All
other customized NVRAM settings are retained.

parameters.
