If it is
properly designed and installed, it will NOT be removable
until after the lock is unlocked. Why have a lock that can simply be
removed instead of using the key?
But, then again, wasn't this about an IBM product?
DEC and DG just used the
locks to eliminate non-operator use of
the control panel, not to eliminate non-authorized access to
the hardware. IBM locked the boxes to eliminate service types as
well as non-operator use of the controls.
If you don't eliminate non-authorized access to the hardware, then how
could you eliminate non-operator use of the control panel? A
non-operator could merely bypass the lock, or replace it with their own.
Or is it merely intended to be a polite request and reminder?
ANY properly designed and installed lock must be unlocked before it can be
removed.
