Chapter 2: Adapter Installation Instructions
This chapter provides detailed instructions on how to install your adapter. To install the adapter, follow these steps:
1. Unpack your adapter.
Unpack and remove the adapter. Inspect the adapter for damage.
ATTENTION To avoid the risk of data loss, back up your data before you change your system configuration.
2. Turn off the power to the system.
Turn off the power to the computer, and disconnect the AC power cord. Remove the computer cover. Refer to the
system documentation for instructions. Before you install the adapter, make sure that the computer is disconnected
from the power and from any networks.
CAUTION Disconnect the computer from the power supply and from any networks to which you will install
the adapter, or you risk damaging the system or experiencing electrical shock.
3. Review the adapter connectors.
4. Check the mounting bracket on the adapter.
If required for your system, replace the full-profile mounting bracket that ships on the adapter with the low-profile
bracket supplied. Complete the following steps to attach the low-profile bracket.
a. Using a No. 1 Phillips screwdriver that is ESD safe, remove the two Phillips screws that connect the full-profile
bracket to the board. Unscrew the two screws located at the top and bottom edges of the board. Avoid touching
any board components with the screwdriver or the bracket.
b. Remove the full-profile bracket. Do not damage the adapter.
c. Place the adapter on top of the low-profile bracket. Position the bracket so that the screw holes in the tabs align
with the openings in the board.
d. Using a No. 1 Phillips torque screwdriver that is ESD safe, set to a maximum torque of 4.8 ±0.5 inch-pounds.
Replace the two Phillips screws removed in Step a.
ATTENTION Exceeding this torque specification can damage the board, connectors, or screws, and can void
the warranty on the board. Damage caused to the board as a result of changing the bracket can
void the warranty on the board. Adapters returned without a bracket mounted on the board will be
returned without return merchandise authorization (RMA) processing.
5. Insert the adapter into an available PCIe slot. Select a PCIe slot, and align the adapter’s PCIe bus connector to the
slot, as shown in the following figure. Press down gently, but firmly, to make sure that the adapter is seated correctly
in the slot. Secure the bracket to the computer chassis with the bracket screw.
Refer to ThinkSystem Server Documentation Center, select your product, and review the Install server hardware
options section for detailed instructions.
NOTE Adapters with a x8 host interface can operate in x8 or x16 slots. However, some x16 PCIe slots
support only PCIe graphics cards; an adapter installed in one of these slots will not function. Refer to
the guide for your motherboard for information about the PCIe slots.
NOTE The shape, size, and locations of the components on your adapter and its bracket might vary from
this illustration.

6. Configure and install the SAS and SATA devices in the host computer case.
Refer to documentation for the devices for any pre-installation configuration requirements.
7. Connect the adapter to the devices. Connect the appropriate cable with the connectors on one end to connect to the
adapter and the appropriate connector on the other end to attach to the backplane connector.
8. The maximum cable length is 1 meter (39.37 in.). A single wide-port SAS device cannot connect to phys controlled by
different SAS cores or PDBs.
Refer to ThinkSystem Server Documentation Center, select your product, and review the Internal cable routing
section for detailed instructions.
9. Provide the required airflow for the installed adapter.
10. Turn on the power to the system. Reinstall the computer cover, and reconnect the AC power cords. Make sure that
the power is turned on to the storage devices before or at the same time that the power is turned on to the host
computer. Turn on power to the host computer. If the computer is powered on before these devices, the devices might
not be recognized.
During boot, a BIOS message appears. The firmware takes several seconds to initialize. The configuration utility
prompt times out after several seconds. The second portion of the BIOS message shows the adapter controller
number, firmware version, and cache SDRAM size. The numbering of the adapters follows the PCIe slot scanning
order used by the host motherboard.
11. Choose the correct storage profile.
12. Install the operating system driver. The adapters can operate under various operating systems. To operate under
these operating systems, you must install the software drivers.
The hardware installation of your adapter is complete.
