Thank you for contacting Intel Customer Support.
Based in your description, the back-plane you plan to use is not compatible with that chassis.
I would like to recommend using the Pedestal Chassis Hot Swap Drive Kit FUP4X35HSDK or Spare 8x2.5 Hot-Swap Drive Cage Kit FUP8X25HSDKS. In addition to this, the cables compatible for the implementation you should be the AXXCBL650MSMS and AXXCBL650MSMS [mini-SAS to mini-SAS].
** The mini-SAS to x4 SATA can be use only from the on-board mini-SAS to the SATA ports on the back-plane.
Thanks for the reply. The drive cage came with the chasis its self. Unsure how Intel would sell an incompatible bundle?.... anyway I bought a replacment sas to sata reverse cable and it worked right away, so a faulty cable was the cause.
