You can use only the 2.5-inch hot-swap drivebackplanes with this adapter. You can use the Expansion Adapter only with the following RAIDcontrollers:ServeRAID M1015 SAS/SATA adapterServeRAID M5014 SAS/SATA adapterServeRAID M5015 SAS/SATA adapterThe Expansion Adapter must be installed in PCI Slot 1 and the ServeRAID adapter must be installed inPCI Slot 3.
