Local Port Operation 67
When you attempt to preempt another user or Admin, a message appears on your
screen, and a Preempt Warning appears on the screen of the user or Admin.
These dialogs appear for the time assigned in the Timeout Seconds field set
through either the local OSD or the HP IP Console Viewer. If the person you are
preempting does not respond within the time assigned, they are disconnected and
the preempt is granted.
