6-10 Sun Blade 1500 Service, Diagnostics, and Troubleshooting Manual • December 2004
6.4.1 Stop-A Command
Use the Stop-A command to abort an OpenBoot process. To issue the Stop-A
command for the Sun Blade 1500 workstation, press both the Stop and A keys (Stop-
A) immediately after powering on the workstation. Hold both keys down until the
workstation beeps.
Caution – Performing the Stop-A command while the Solaris operating system is
running causes a system halt. The system state is lost, file systems are not
synchronized, and data might be lost or corrupted.
Note – Using Stop-A does not allow the workstation to perform a core dump. This
information could be useful to you if the operating system has crashed.
6.4.2 Stop-N Equivalent Command Procedure
For older Sun systems, issuing the Stop-N command upon startup resets workstation
configuration variables. The Sun Blade 1500 workstation uses a Sun Type-6 USB
keyboard. It is not possible to issue a Stop-N command with a USB keyboard
because by the time the USB keyboard driver is loaded, the interval to use the Stop-
N command has expired. Instead, the following Stop-N equivalent procedure must
be used to reset your workstation configuration variables. This procedure puts the
Sun Blade 1500 workstation into a Safe NVRAM mode.
6.4.2.1 Resetting the NVRAM Temporarily
1. Power on the workstation and wait until the front panel Power button LED begins
to flash and you hear a beep.
2. Quickly press the front panel Power button twice (similar to the way you would
double-click a mouse).
Note – Once the Power button LED stops flashing and stays lit, pressing the Power
button again powers off the system.
