Platform Media Bay Module Bays and Backplane
The number and configuration of the media bay modules depend on the number of bays available
in the platform base chassis and DS30 system resources. The BCM200 platform base chassis
provides two media bay module bays. The BCM400 platform base chassis provides four media
bay module bays.
All media bay module bays must contain either a media bay module or a MBM filler blanking
plate. Populate the bays with media bay modules as required. Fill unpopulated media bay module
bay openings in the platform base chassis with the MBM filler blanking plate (see Figure 10).
