OCP Operating Modes
System Mode
System mode is the normal mode of operation, in which commands are issued through
the drive’s serial interface. In system mode, the OCP displays the status associated with
actions such as loading, rewinding, or moving a tape.
User Mode
User mode which is employed when a user is pushing buttons on the front panel.
When an OCP button is pressed and released, the OCP automatically transitions to user
mode. User mode continues for up to three minutes after a user stops pushing buttons,
or until the requested robotic action stops, whichever is longer. At that time, the OCP
returns to system mode.
Security PIN
It the user security feature is activated, the user mode is restricted to information menu
items until a correct PIN is entered.
