Figure 31. Hard disk drive backplane (lower) installation
Align the backplane with its location in the server; then, insert the backplane and push it down until
it is fully seated.
Step 3. Repeat Step 1 on page 150 and Step 2 on page 150 for each hard disk drive backplane being
installed in the lower compute tray.
Step 4. 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 the compute system board; then, connect the
NVME cable.
Step 5. Make sure that all power cables are connected to the storage interposer.
Step 6. Route any cables that were moved to access the backplanes and connectors.
After you install the hard disk drive backplane:
1. Install the storage interposer and connect all cables. See "Install a storage interposer (lower tray)" on
page 185.
2. Make sure that all of the cables are correctly routed after they have been connected.
3. Install the fan cage. See "Install a fan cage (lower tray)" on page 137.
4. If you have no additional options to install in the lower compute tray, install it. See "Install the compute
tray (fully removed)" on page 125.
5. Install any hard disk drives that you removed from the lower compute tray. Each drive should be
installed in its original location. See "Install a hard disk drive" on page 141.
6. If you have no additional options to install in the upper or lower compute tray, install the front cover. See
"Install the front cover" on page 65.

Install a hard disk drive

Insert the hard disk drive in its bay and close the latch handle to lock the drive in place. Hard disk drives are
hot-swap devices that can be installed while the server is powered on.
