Install A Hard Disk Drive - Lenovo ThinkSystem SR950 Setup Manual

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 224 and Step 2 on page 224 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 40.
• 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 373.
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 320.
4. If you have no additional options to install in the lower compute tray, install it into the chassis. See
"Install a compute tray" on page 307.
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 324.
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 227.

Note: If you are installing an optional hard disk drive backplane, perform that task first. See "Install a hard
disk drive backplane (upper tray)" on page 220 or "Install a hard disk drive backplane (lower tray)" on page
223.
Before installing a hard disk drive, make sure that it is compatible with both the server and its configuration.
See "Hard disk drive installation considerations" on page 226 for information.
Before you install a hard disk drive:
1. If the hard disk drive bay contains a filler, press the release tab and pull the filler from the bay.
Hard disk drive fillers can be of two types: single-bay fillers and four-bay fillers. If you remove a four-bay
filler and are not installing four hard disk drives, you must install single-bay fillers in each of the empty
drive bays.
