Chapter 6 Configuring System Firmware 121
How to Implement Stop-N Functionality
Before You Begin
This procedure implements Stop-N functionality on Sun Fire V890 systems,
temporarily resetting OpenBoot configuration variables to their default settings. This
procedure is most useful if you have not configured your Sun Fire V890 system to
run diagnostic tests. You might find it more convenient to use the alternative method
of placing the system keyswitch in Diagnostics position. For more background, see:
■ “About OpenBoot Emergency Procedures” on page 119
For information about the system keyswitch, see:
■ “About the Status and Control Panel” on page 11
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 V890 system to run diagnostic tests, this
could take upwards of 30 minutes.
