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.
