Note – To reconfigure a processor, you must power cycle the system. The
reset-all command will not suffice to bring the processor back online.
How to Implement Stop-N Functionality
Before You Begin
This procedure implements Stop-N functionality on Sun Fire V490 systems,
temporarily resetting OpenBoot configuration variables to their default settings. This
procedure is most useful if you have not configured your Sun Fire V490 system to
run diagnostic tests. You might find it more convenient to use the alternative method
of placing the system control switch in the Diagnostics position. For more
background, see:
■ “About OpenBoot Emergency Procedures” on page 54
For information about the system control switch, see:
■ “System Control Switch” on page 15
What to Do
1. Turn on the power to the system.
If POST diagnostics are configured to run, both the Fault and Locator LEDs on the
front panel will blink slowly.
2. Wait until only the system Fault LED begins to blink rapidly.
Note – If you have configured the Sun Fire V490 system to run diagnostic tests, this
could take upwards of 30 minutes.
