■ Section 22.1, “Overview of the MEDBP” on page 22-1
■ Section 22.2, “Cold Replacement” on page 22-5
As a replacement method for MEDBPs, only the cold replacement method can be

22.1 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.
FIGURE 22-1 , FIGURE 22-2 , and FIGURE 22-3 show the mounting locations of the MEDBP
of M8000, M9000 (base cabinet), and M9000 (with the expansion cabinet),
respectively.
