Note:
If you do not have an American Megatrends Olympus II (series 821) motherboard, you
cannot use the I2C connector to monitor the hardware health of the motherboard.
Note:
If you do not use the
chassis power on switch
or
chassis reset switch
pins, you should
place a plastic cap on them so that they do not short your motherboard. Do not use a
standard jumper. It will short the connection.
