On DIGITAL UNIX or OpenVMS systems, used to protect
inadvertent or inadvisable entry into SRM console mode by
typing Ctrl/P at the console device. For example, you might
push this button in when a critical program is running, in case
someone might unknowingly try to enter SRM console mode
to load new console code or otherwise use the console device.
For Windows NT systems, the Secure pushbutton is used in
controlling transitions from the Windows NT operating
system to the SRM console, as described in Section 8.2.
Out
Allows input from the console device. See above.
Restart
In
Momentary switch used to reinitialize the system. Registers

thus restart the system without removing power from the
system, which can cause wear and tear on the machine.
