Chapter 1: Overview

The Thinksystem RAID 940-16i 8GB Flash PCIe Gen4 12Gb Internal Adapter, based on the SAS3916 tri-mode controller,

is a high-performance PCIe-to-SATA/SAS/PCIe (tri-mode) storage adapter. The tri-mode SerDes technology enables

operation of SAS, SATA, or PCIe (NVMe) storage devices in a single drive bay. A single controller can operate in all three

modes concurrently: SAS, SATA, and PCIe/NVMe. The adapter negotiates between the speeds and the protocols to

recognize and concurrently interface with these three storage devices types.

The adapter provides the following storage interface data transfer rates:

SAS data transfer rates of 12Gb/s, 6Gb/s, and 3Gb/s per phy

SATA transfer rates at 6Gb/s and 3Gb/s per phy

PCIe (NVMe) data transfer rates of 16 GT/s, 8 GT/s, 5 GT/s, and 2.5 GT/s per lane

Chapter 2: Hardware Installation Instructions

To install the adapter, follow these steps:

1. Unpack the adapter and inspect the adapter for damage.

Unpack the adapter in a static-free environment. Remove the adapter from the antistatic bag, and carefully inspect the

adapter for damage. If you notice any damage, contact Lenovo or your reseller support representative.

ATTENTION To avoid the risk of data loss, back up your data before you change your system configuration.

2. Review the adapter connectors.

3. Check whether the adapter is well-fixed on the mounting bracket.

The adapter ships preinstalled on a mounting bracket. Check that the adapter is fixed in place. If any loose screws

exist, tighten the screws using a No.1 Phillips torque screwdriver. The maximum torque is 4.8 ± 0.5 inch-pounds.

ATTENTION Exceeding this torque specification can damage the board, connectors, or screws, and can void

the warranty on the adapter. Damage caused to the adapter 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.

4. Prepare the server.

Turn off the power to the server and disconnect all power cords.

5. Remove the top cover from the chassis.

6. Remove any components that might impede the adapter installation.

Refer to ThinkSystem Server Documentation Center, select your product, and review the Hardware replacement

procedures section for detailed instructions.

7. Install the adapter.

Align the notches on the mounting bracket with the four pins or three pins on the chassis, place down the adapter, and

slightly slide the adapter to secure it in place, as the following figure shows.

ATTENTION The shape, size, and locations of the components on your adapter and its bracket might vary

from the following illustration.

Figure 2 Installing the Adapter

8. Connect any cables to the adapter.

Refer to ThinkSystem Server Documentation Center, select your product, and review the Internal cable routing

section for detailed instructions.

and User Guide

9. Reinstall any parts that have been previously removed and connect any internal cables.

Refer to ThinkSystem Server Documentation Center, select your product, and review the Hardware replacement

procedures section and the Internal cable routing section for detailed instructions.

10. Reinstall the top cover on the chassis.

Refer to ThinkSystem Server Documentation Center, select your product, and review the Hardware replacement

procedures for detailed instructions.

11. Reconnect any external cables and turn on the power to the system.

The hardware installation of your adapter is complete.
