Note: Unless explicitly instructed otherwise by the manufacturer, do not move the
jumpers from their default location. Doing so will likely cause the card to become
disabled. Jumpers not detailed below are unpopulated.
JP3, JP2, and JP1 are used to configure the SMBus address at which the card is
discovered by the BIOS. By default, it is set to "A0" and can be configured to another
value to avoid an address conflict with other devices on the SMBus. It should never
be changed unless explicitly instructed by Supermicro.
