Overheat (OH)/Fan Fail
Connect an LED cable to OH/Fan Fail connections on pins 7 and 8 of JF1 to provide warnings
for chassis overheat/fan failure. On X11SCZ-F, this connection will also serve as an IPMI UID
indicator as a blue LED. Refer to the table below for pin definitions.
Power Button
The Power Button connection is located on pins 1 and 2 of JF1. Momentarily contacting both
pins will power on/off the system. This button can also be configured to function as a suspend
button (with a setting in the BIOS - see Chapter 4). To turn off the power in the suspend
mode, press the button for at least 4 seconds. Refer to the table below for pin definitions.
