You can optionally connect a normally-open momentary-contact switch
between terminals 11 and 12 at each adapter. Such a reset switch would be
particularly useful if processor-restart lockout is selected. If a fault is
detected at the I/O chassis, you can use the reset switch to reset the adapter
in an attempt to restart the I/O chassis.
