Mark I had a glance in the redbook searching on "dedicated". On page 34 there is a discussion of recommendations which appears to be concerned to lead the reader by the hand through the consideration that, as I see it, if the OSA-ICC is the *only* console facility available, you had better make sure you have reliable redundancy. I expect the redbook authors are thinking of how the OSA-ICC compares with a 3270 display coax-attached to some sort of channel-attached controller.
You simply need to do exactly that, namely, worry suitably about how reliable your "console" function is. What would you do if any one of the components which provides you with a "console" through an OSA-ICC fails? If your power supply units are unreliable, you may like to introduce some redundancy there. You may also like to worry about two simultaneous failures and so on ...
