Complete the following steps to install a hard disk drive backplane in the upper compute tray or optional
storage tray.
Watch the procedure. A video of the replacement process is available:

Step 1. Connect the power cable to the backplane. If this cable is connected to the storage interposer, you
might find it easier to disconnect it from the storage interposer and then reconnect it to the storage
interposer after the backplane is installed. See “Cable routing for drives” on page 29.
Step 2. Install the hard disk drive backplane.
Note: Existing cables might need to be removed from their retaining clips or moved to the side to
install the backplane.

Align the backplane with its location in the tray; then, insert the backplane and push it down until it
is fully seated.
Step 3. Connect the data cables to the backplane. (SAS backplanes have only one data cable. NVME
backplanes have two data cables.) See “Cable routing for drives” on page 29.
Step 4. Repeat Step 1 on page 148, Step 2 on page 148, and Step 3 on page 149 for each hard disk drive
backplane being installed in the upper tray.
Step 5. Turn the tray upside down.
Step 6. Route and connect the data cables. See “Cable routing for drives” on page 29.
• Route each SAS data cable to its connector on the RAID adapter; then, connect the SAS cable.
• Route each NVME data cable to its connector on a compute system board or optional storage
tray; then, connect the NVME cable.
Step 7. Make sure that all power cables are connected to the storage interposer.
Step 8. Make sure that all of the cables are correctly routed after they have been connected.
After you install the hard disk drive backplane:
