A. M.2 Socket 1
B. M.2 Socket 2
Activity LEDs
There are two Activity LEDs on the AOC-SLG3-2M2 designated as LED1 and LED2.
See the table below for information.
The AOC-SLG3-2M2 LEDs
| Activity LED Status | ||
| LED | Color | Status |
| LED1 | Green | Blinks whenever there is any read or write activity on M.2 Socket 1 |
| LED2 | Green | Blinks whenever there is any read or write activity on M.2 Socket 2 |
Standoffs
The AOC-SLG3-2M2 is designed with movable standoffs which support three different M.2 SSD lengths. Place the standoffs as indicated below:
| M.2 Length | Standoff Positions |
| 22 mm x 110 mm | 1: SRW5 and SRW6 |
| 22 mm x 80 mm | 2: SRW3 and SRW4 |
| 22 mm x 60 mm | 3: SRW1 and SRW2 |

Front Jumper Locations and Settings
The AOC-SLG3-2M2 Jumpers
Explanation of Jumpers
To modify the operation of the backplane, jumpers can be used to choose between optional settings. Jumpers create shorts between two pins to change the function of the connector. Pin 1 is identified with a square solder pad on the printed circuit
board. Note: On two pin jumpers, “Closed” means the jumper is on and “Open” means the jumper is off the pins.
These jumpers are used to configure the SMBus address where the AOC is detected by the BIOS. The default SMBus address is set to “A0”; however, it can also be configured to a different setting to avoid possible address conflict 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.
Note: Unless explicitly instructed otherwise by the manufacturer, do not move the jumpers from their default locations. Doing so may disable the jumpers. Jumpers not documented below are unpopulated.
| SMB Address 1-2=0, 2-3=1 | |||
| JP3 A2 | JP2 A1 | JP1 A0 | Hex Address |
| 0 | 0 | 0 | A0 |
| 0 | 0 | 1 | A2 |
| 0 | 1 | 0 | A4 |
| 0 | 1 | 1 | A6 |
| 1 | 0 | 0 | A8 |
| 1 | 0 | 1 | AA |
| 1 | 1 | 0 | AC |

Installation
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 sufficient 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
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
- Power down the system and remove the power cord from the rear of the power supply.
- 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.
- 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.
- Insert one or two M.2 SSDs into the slots on the expansion card. Then push it flat against the carrier card and the plastic standoff.
Inserting a M.2 SSD into an Expansion Card Slot
Securing the M.2 SSD to the Expansion Card
- Secure each M.2 card by pushing the standoff into place in the mounting hole designated as 60 mm, 80 mm, or 110 mm.
The M.2 SSD secured to the Expansion Card
- 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.
- Plug the power cord into the rear of the power supply and power up the system.
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 Configuration -> North Bridge -> IIO Configuration -> CPU Configuration -> 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 Configuration -> NVMe Firmware Source -> AMI Native Support.
Refer to the applicable system or motherboard user’s manual.
