The Schroff ATCA Shelves are designed to work with two redundant Schroff ShMM-ACB-V
Shelf Managers in dedicated Shelf Manager slots.
Upon request is also a version with on-blade shelf management available. With on-blade
shelf management, the I²C components of the PEMs and the SEEPROM are connected to the
internal I²C bus on the Fan Trays. The on-blade Shelf Manager has access to these
components via the IPM controller of the Fan Trays.
