Chapter 6 Configuring System Firmware 139
Stop-A Functionality
Stop-A (Abort) works the same as it does on systems with standard keyboards,
except that it does not work during the first few seconds after the machine is reset.
Stop-N Functionality
1. After turning on the power to your system, wait until the system Fault LED on the
front panel begins to blink.
2. Press the front panel Power button twice (with a short, one-second delay in
between presses).
A screen similar to the following is displayed to indicate that you have successfully
reset the NVRAM configuration variables to the default values:
Note that some NVRAM configuration variables are reset to their defaults. They
include variables that are more likely to cause problems, such as TTYA settings.
These NVRAM settings are only reset to the 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 variables.
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.
