Fan Headers
The X11SCA/-W/-F has five fan headers (FAN1-FAN5). All of these 4-pin fan headers are
backwards-compatible with the traditional 3-pin fans. However, fan speed control is only
available for 4-pin fans by Thermal Management via the IPMI 2.0 interface. See the table
below for pin definitions.
Speaker/Buzzer Header
On the SPKR header, pins 1-4 are for the speaker and pins 3 and 4 are for the buzzer. If
you wish to use an external speaker, connect its cable to pins 1-4.
