Overview of the MEDBP

This section provides an overview of MEDBPs and describes their mounting
locations.
A MEDBP provides the connectors for mounting a tape drive unit (TAPEU) and
CD-RW/DVD-RW drive unit (DVDU) in a cabinet. These connectors serve as sockets
on the cabinet side for connecting a tape drive unit and CD-RW/DVD-RW drive unit
to the cabinet. A MEDBP is further connected to a switch backplane, through which
it connects the tape drive unit or CD-RW/DVD-RW drive unit to the IOU. Active
maintenance cannot be performed on a MEDBP.
