1.1.3 Exiting Console Mode
To exit console mode, type one of the following console commands. These
commands are further described in Appendix B.
• BOOT-This command initializes the CPU and boots the operating system
software from the device specified. If no device is specified, the system
uses the default device in NVR. If no device is listed in NVR, the system
defaults to the Ethernet (ESAO) as the boot device.
The BOOT command starts the system similar to when power is
turned
on except that the power-up tests are not
run.
If the system attempts to
boot over the Ethernet (ESAO) and no response is received, make sure
the node with the operating system software is operating normally and the
software is loaded. Press the halt button if you need to abort the Ethernet
boot.
• CONTINUE-This command instructs the CPU to continue the operating
system software at the address contained in the program counter (PC). This
command starts up the operating software where it was halted provided
no console TEST commands were run. Running a TEST command alters
the PC register and memory so that the operating system software cannot
be started properly by entering the CONTINUE command. If a TEST
command was entered, use the BOOT command to start the operating
system software.
• START- This command starts the operating system software at a specified
address. H no address is given, the contents of the PC register are used.
However, running a TEST command alters the PC register and memory so
that the operating system software cannot be started properly by entering
the START command. If a TEST command was entered, use the BOOT
command to start the operating system software.
1.2 Running Power-Up Tests
Power-up tests
run
each time the system power is
turned on and, if the tests
are successful, the operating system starts booting. Power-up testing consists
of a sequence of tests executed for each device installed in the system. The
test number of each device is listed on the power-up screen display as the
device is tested. LEDs on the rear of the system box indicate the status of the
system as it is powered up. Appendix G lists the definitions of the LEDs if
you need them.
