Passively Managed Chassis

Figure 34-4 on page 997 pictures a passively managed chassis. A passively managed chassis provides access to each IBA module's ModuleInfo attribute (see Table 34-2 on page 998) through a BM access to the BMA on each module, and access to the each module's ChassisInfo attribute through a BM access over the module's point-to-point IB-ML bus. Over its dedicated IB-ML link, each module permits access to its unique ChassisInfo attribute that provides the ChassisGUID as well as the slot number the module is installed in.
