3.Press the front panel Power button twice, with no more than a short, one-second delay in between presses.

A screen similar to the following is displayed to indicate that you have temporarily reset OpenBoot configuration variables to their default values:

Setting NVRAM parameters to default values.

Sun Fire V490, No Keyboard

System is operating in Safe Mode and initialized with factory default configuration. No actual NVRAM configuration variables have been changed; values may be displayed with ’printenv’ and set with ’setenv’. System will resume normal initialization and configuration after the next hardware or software reset.

Note – Once the front panel LEDs stop blinking and the Power/OK LED stays lit, pressing the Power button again will begin a graceful shutdown of the system.

During the execution of OpenBoot firmware code, all OpenBoot configuration variables—including the ones that are likely to cause problems, such as input and output device settings—are temporarily set to “safe” factory default values. The only exception to this is auto-boot, which is set to false.

By the time the system displays the ok prompt, OpenBoot configuration variables have been returned to their original, and possibly misconfigured, values. These values do not take effect until the system is reset. You can display them with the printenv command and manually change them with the setenv command.

If you do nothing other than reset the system at this point, no values are permanently changed. All your customized OpenBoot configuration variable settings are retained, even ones that may have caused problems.
