UID LED
Connect an LED to pins 7 and 8 of JF1 to provide advanced warning of chassis overheating or fan failure. These pins also work with the front UID indicator, which will activate as either a solid or flashing blue LED depending on whether the LED was activated via IPMI or the UID button. Refer to the tables on the right for pin definitions and status indicators.
Power Fail LED
The Power Fail LED connection is located on pins 5 and 6 of JF1. Refer to the table on the right for pin defini- tions.
Reset Button
The Reset Button connection is lo- cated on pins 3 and 4 of JF1. Attach it to the hardware reset switch on the computer case. Refer to the table on the right for pin definitions.
Power Button
The Power Button connection is located on pins 1 and 2 of JF1. Mo- mentarily contacting both pins will power on/off the system. This button can also be configured to function as a suspend button (see the Power Button Mode setting in BIOS). To turn off the power when set to suspend mode, depress the button for at least 4 seconds. Refer to the table on the right for pin definitions.
