Halting The System; Resetting The System - Digital Equipment MicroVAX 3600 Operation

Once you have completed the recommended procedure, you can turn off
your system by setting the on/off switch to 0.
2.7 Halting the System
Halting the system interrupts all processes and returns control to the console
program. You may need to halt the system during software installation. Or,
you may want to boot the system from another device; for example, a tape
cartridge containing MicroVAX Diagnostic Monitor (MDM) software.
CAUTION: Halting your system without following the shutdown procedure
described in your system software manuals may result in loss of data.
To halt the system, press in the Halt button located on the mass storage
control panel. When the console mode prompt »> appears on your screen,
the system is halted. Before you can enter console commands, press the Halt
button again to return it to the out position. Now you can enter console
commands. If you inadvertently press the Halt button, type "c

An alternative way to halt the system is to first set the Break Enable/Disable
switch on the CPU cover panel to enable (indicated by the dot inside the
circle).
NOTE: When you change the Break Enable/Disable switch from one setting to
the other, you must activate the new setting by resetting, the system. To reset
the system, press the Reset button on either power supply. All processes will be
interrupted.
Once the Break Enable/Disable switch setting is enabled, halt the system
by pressing
Break
on the console terminal. When the console mode prompt
»> appears on your screen, the system is halted. This is the only means of
halting the system on early models of MicroVAX 3600 and VAXserver 3600

If you inadvertently halt the system by either method, type "c
Return " (for
continue) at the console prompt. The processes interrupted by the halt
