jumpers can be used to choose between

the jumper is off the pins.

These jumpers are used to congure the SMBus address where the AOC is detected

by the BIOS. The default SMBus address is set to "A0"; however, it can also be

congured to a different setting to avoid possible address conict with another device

installed on the same SMBus. Please do not change the default setting unless you

are explicitly instructed to do so by Supermicro. It should never be changed unless

explicitly instructed by Supermicro.

Installation

3-1 Static-Sensitive Devices

Electrostatic Discharge (ESD) can damage electronic com ponents. To avoid dam-

aging your expansion card, it is important to handle it very carefully. The following

measures are generally sufcient to protect your equipment from ESD.

Precautions

• Use a grounded wrist strap designed to prevent static discharge.

• Touch a grounded metal object before removing the expansion card from the

antistatic bag.

• Handle the expansion card by its edges only; do not touch its components or

peripheral chips.

• Put the expansion card back into the antistatic bags when not in use.

• For grounding purposes, make sure that your system chassis provides excellent

conductivity between the power supply, the case, the mounting fasteners and

the expansion card.

Unpacking

The expansion card is shipped in antistatic packaging to avoid static damage. When

unpacking your component, make sure you are static protected.

Note: To avoid damaging your components and to ensure proper installation, be

sure to always connect the power cord last, and always remove it before adding,

removing or changing any hardware components

.

3-2 Installing Expansion Cards

The AOC-SLG3-2M2 supports two M.2 SSDs in 60 mm, 80 mm, or 110 mm length.

Visit the Supermicro website for a current list of supported M.2 SSDs.

Installing Expansion Cards

1. Power down the system and remove the power cord from the rear of the

power supply.

2. Use industry-standard anti-static equipment (such as gloves or wrist strap)

and follow the precautions on page 3-1 to avoid damage caused by ESD.

3. For each SSD, install the standoff in the appropriate hole that corresponds

with the form factor of the SSD to be installed (60 mm, 80mm, or 110 mm

length SSDs are supported). Push the plastic standoff until it snaps into the

carrier card.

4. Insert one or two M.2 SSDs into the slots on the expansion card. Then push it

at against the carrier card and the plastic standoff.

Securing the M.2 SSD to the Expansion Card

5. Secure each M.2 card by pushing the standoff into place in the mounting hole

designated as 60 mm, 80 mm, or 110 mm.

6. Simultaneously slide the expansion card bracket into the PCIe slot of the

chassis, while plugging the expansion card into the appropriate slot on the

motherboard.

7. Plug the power cord into the rear of the power supply and power up the

system.

3-3 Additional Settings

Depending on the system, motherboard, and BIOS version, the following BIOS

settings may be necessary for the proper operation of M.2 NVMe drives:

• Having the CPU IOU settings set to x4x4x4x4 PCIe bifurcation. This option may

be found under BIOS Setup -> Advanced -> Chipset Conguration -> North

Bridge -> IIO Conguration -> CPU Conguration -> IOU Setting -> x4x4x4x4.

• Having the NVMe Firmware Source set to AMI Native Support. This option may

be found under BIOS Setup -> Advanced -> PCIe/PCI/PnP Conguration ->

NVMe Firmware Source -> AMI Native Support.

Refer to the applicable system or motherboard user's manual.
