Replacing the disk drive backplane in the 8408-44E or 8408-E8E

To replace the disk drive backplane, complete the steps in this procedure.

1. Ensure that you have the electrostatic discharge (ESD) wrist strap attached. If not, attach it now.
2. Slide the disk drive backplane (B) into position on the RAID assembly. Ensure the pins (A) on the bottom side of the disk drive backplane are inserted into the slots on the RAID assembly. See Figure 1.
   Figure 1. Replacing the disk drive backplane

   
3. Replace four screws on each side of the RAID assembly by using a T10 Torx screwdriver. See Figure 2.
   Figure 2. Replacing the screws

   
4. Slide the RAID assembly cover (A) in the direction that is shown until the latches (B) lock in position, as shown in Figure 3.

7. Replace the disk drives into their original positions.
   1. Unlock the drive bay handle (A) by pressing it and pulling it out toward you. If the handle is not all the way out, the drive does not slide into the system.
   2. Hold the drive by the top and bottom edges as you position the drive, and insert it into the drive slot. Do not hold the drive by the handle.
   3. Slide the drive all the way into the system, and push the drive bay handle (A) in until it locks, as shown in Figure 6.
      Important: Ensure that the drive is fully seated and is all the way into the system.
   4. Repeat step 7 for the remaining disk drives.

8. Replace the solid-state drives (SSD) into their original positions.
   1. With the solid-state drive handle (A) in the unlocked position, pull the lever outward to gain access to the guide rails in the SSD slot. Support the bottom of the SSD as you align it with the guide rails in the SSD slot.
      Note: Do not hold the drive only by the handle. Support the drive by holding the drive by its sides.
   2. Slide the SSD into the system until the drive stops, and then lock the SSD by rotating the handle (A) in the direction shown.
      Important: When you install an SSD, ensure that the SSD is fully seated and is all the way into the system.
   3. Lock the drive by rotating the handle (A) in the direction that is shown in Figure 7.
   4. Repeat step 8 for the remaining solid-state drives.

9. Replace the DVD drive.
   1. Align the DVD drive with the media bay, and support the bottom of the drive as you slide it halfway into the system.
   2. Push the DVD drive fully into the system until the device locks in place. See Figure 8.
