  4. Orient the hard drive backplane assembly with the connectors on the backplane facing toward the back of the server.
  5. Insert the hard drive backplane into the server and position it against the back wall of the drive bay (2).
  6. Hold the hard drive backplane assembly flat against the back wall of the drive bay and align the screw holes in the assembly with the captive screws.

    For ease of installation, align the center screw first.

  7. From the front of the server, use a No. 1 Phillips screwdriver to tighten the three captive screws and secure the hard drive backplane assembly (3).
  8. Connect the SAS cables and the one SAS power cable to the hard drive backplane (4).

    See Hard Drive Backplane Cable Routing and Designations for cable routing and designations.

  9. Install the hard drives into their original slots. See How to Install a Hard Drive.
  10. Install the CMODs and filler modules into their original slots. See How to Install a CPU Module (CMOD).
  11. Install the AC power cables. See How to Remove and Install AC Power Cables.
  12. Prepare the server for operation. See How to Prepare for Operation.
