JP12 Recovery Mode Jumper
This jumper is primarily used to recover a failed flash attempt. By shorting pins two and
three, you can place your MegaRAC G3 card into
Recovery Mode . See Appendix C,
Remote Recovery Application (RRA) for more information on how to recover your
MegaRAC G3 card. By default, pins one, two and three are open.

JP13 and JP14 PCI Bus SMB Data and Clock Jumper
These two headers allow your MegaRAC G3 card to read I2C bus information. If your
hosts system’s motherboard has support for I2C on the PCI slots, place a jumper on these
two headers. By default these headers are open.
Note:
Only revision B1 and newer revisions of the MegaRAC G3 cards have these two jumpers.
Revisions A and B do not have JP13 and JP14.
Note: Most PCI slots have a “floating” I2C bus. A “floating” I2C bus means that there is no
physical connection between the two I2C pins on the PCI slot and the motherboard’s I2C
bus. Shorting JP13 and JP14 would be useless in this case.
Note: JP13 and JP14 can be used in place of the MegaRAC Feature Cable to gather I2C bus
information from the motherboard.
Note: Only the OEM version can utilize the hardware health monitoring capabilities of
MegaRAC G3 card. The hardware health monitoring function requires an OEM specific
cable and
Sensor Definition Kit (SDK/SDR) file and Soft Processor (SP) file.
