Chapter 5: Advanced Serverboard Setup

SGPIO

The T-SGPIO1/ T-SGPIO2 (Serial General Purpose Input/Output) headers provide a bus between the SATAcontroller and the backpane to provide SATA enclosure management functions. Connect the appropriate cable from the backplane to the T-SGPIO1 header to utilize SATA management functions on your system.

Likewise, the 3-SGPIO1/3-SGPIO2 headers provide the same function between the SAS controller and the backpane, and have the same pin definitions (only on H8QG6-F).

SMBus Header

The header at SMBus is for the System Management Bus. Connect the appropriate cable here to utilize SMB on the system. See the table on the right for pin definitions.

Wake-On-LAN

The Wake-On-LAN header is designated JWOL. See the table on the right for pin definitions. You must have a LAN card with

aWake-On-LAN connector and cable to use the Wake-On-LAN feature.

Power I2C

The JPI2C1 header is for power I2C, which may be used to monitor the status of the power supply, fan and system temperature. See the table on the right for pin definitions.
