Note - It is not necessary to completely remove the storage drives from the server; simply pull them out far enough to disengage them from the disk backplane. If you do remove the storage drives from the server, make a note of their locations so that you can reinstall them in the same locations.

Disconnect the cables from the storage drive backplane.
1. Disconnect the two power cables and the auxiliary signal cable from the storage drive backplane [1].
2. If present, disconnect the two optional NVMe cables from the storage drive backplane [2].
3. Disconnect the SAS cable from the storage drive backplane to the rear-mounted storage drives, and the two SAS cables from the storage drive backplane to the Oracle Storage 12 Gb/s SAS PCIe RAID HBA [3].
  Note the cable connections in order to ease proper reconnection of the cables.

Using a No. 2 Phillips screwdriver, loosen the two spring-mounted screws that secure the storage drive backplane to the chassis [4].
