Now, now, you walk up to the physical console on an AS/400, you're not
going to be able to do a PWRDWNSYS from a sign-on screen, nor can do it
if signed on as a user who doesn't have sufficient authority to do a
PWRDWNSYS. And you might be physically locked out of the front panel.
It's even possible that you might be physically interdicted from
unplugging the box, or shutting it down from the circuit breaker panel.
Not every OS assumes by default that anybody with physical access to the
hardware also has the authority to shut it down.
(And likewise, accounts, including QSECOFR [the closest OS/400
equivalent to root] can be restricted to certain physical terminals.)
