Chapter 6 NVRAM 6-11
A screen similar to the following is displayed to indicate that you have successfully
reset NVRAM contents to the default values and are in Safe NVRAM mode. If a
screen similar to the following is not displayed, allow the system to boot, shut down
the system, and repeat steps 1 and 2.
While in the Safe NVRAM mode, some of the NVRAM configuration parameters are
reset to their default values. They include parameters that are more likely to cause
problems, such as TTYA settings. These default NVRAM settings exist only for this
power cycle and are not permanent. If you change configuration parameters while in
Safe NVRAM mode, those changes are permanent and survive a reset.
TABLE 6-4 lists the configuration parameters that are reset to default values, and
describes those values.
