Chapter 2 Introducing the BCM hardware 51

The MBM backplane provides the MBM component interface to the power supply and main card. The MBM backplane mounts at the rear of the MBM bays and is a non-replaceable component. Figure 23 illustrates the BCM200 MBM backplane and connectors.

Media bay modules (MBMs)

The BCM system is modular. You can increase the capacity of the system by adding more media bay modules (MBMs). Each BCM allocates a maximum of six DS30 buses to the MBMs. The number of MBMs that can be added to your system is determined by the number of media bays that are open, combined with the number of DS30 buses each component uses.
