Chapter 10 OpenBoot Emergency Procedures 10-3
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.
■ Typing set-defaults discards any customized NVRAM values and
permanently restores the default settings for all NVRAM configuration
parameters.
Note – After the power-indicator LED stops blinking and stays lit, you can press the
power switch to power off the system.
For more information, see Section 3.9, “Resetting Variables to Default Settings” on
page 3-27.
