A System Management Bus header is located at J22. Connect the appropriate cable here to uti- lize SMB on your system.

Alarm Reset
The system will notify you in the event of a power supply failure. This feature assumes that Super- micro redundant power supply units are installed in the chassis. If you only have a single power supply installed, you should dis- able this (the default setting) with (CN5) to prevent false alarms. See the table on the right for jumper settings. (The Alarm Re- set header is located next to the PWR Fault header and close to Fan3.)
