Overheat LED/Fan Fail (JOH1)

The JOH1 header is used to connect an LED to provide warnings of chas- sis overheating. This LED will blink to indicate a fan failure. Refer to the table on right for pin definitions.

SMB

A System Management Bus header is located at J18. Connect the appropri- ate cable here to utilize SMB on your system.
