Fan Headers
The X11SRA/-F/-RF has five fan headers (FAN1 ~ FAN4, FANA). All of these 4-pin fan headers
are backwards-compatible with the traditional 3-pin fan headers. However, fan speed control
is available for 4-pin fan headers only by Thermal Management via the IPMI 2.0 interface.
Refer to the table below for pin definitions.
Power LED Indicator/Speaker Header
Pins 1-3 of JD1 are used for power LED indicator, and pins 4-7 are for the speaker. Please
note that pins 4-7 are used with an external speaker. If you wish to use the onboard speaker,
you should close pins 6-7 with a cap. Refer to the tables below for pin definitions.
