covers the following:
■ Section 23.1, “Overview of SWBPs” on page 23-1
■ Section 23.2, “Cold Replacement” on page 23-5
As a replacement method for SWBPs, only cold replacement can be used. For the
definition of the replacement method, see
Section 4.1, “Types of Replacement
Procedures” on page 4-2 .
23.1 Overview of SWBPs
This section provides an overview of SWBPs and describes their mounting locations.
A SWBP is connected to a tape drive unit (TAPEU) and CD-RW/DVD-RW drive unit
(DVDU) to an I/O unit (IOU) through the media backplane. An expander that
performs the switching of serial attached SCSI (SAS) interfaces is mounted on a
SWBP. Active maintenance cannot be performed on an SWBP.
FIGURE 23-1 , FIGURE 23-2 , and FIGURE 23-3 show the mounting locations of SWBPs of
M8000, M9000 (base cabinet), and M9000 (with the expansion cabinet), respectively.
