Fan Headers (Fan1~4, Fana); Chassis Intrusion (Jl1) - Supermicro Supero X9SRi User Manual

X9SRi/X9SRE Motherboard Series User's Manual

Fan Headers (FAN1~4, FANA)

The X9SRi/X9SRE series has five fan headers
(Fan 1~Fan 4 and Fan A). These fans are 4-pin
fan headers. Pins 1-3 of these fan headers are
backward compatible with the traditional 3-pin
fans. However, the fan speed control setting
in the BIOS Hardware Monitoring section will
only work with 4-pin fans. This allows the BIOS
to automatically set fan speeds based on the
system temperature. Refer to the table on the
right for pin definitions and fan usage.
Note: We recommend that 4-pin fans
are used on the motherboard.

Chassis Intrusion (JL1)

A Chassis Intrusion header is located at JL1 on
the motherboard. Attach the appropriate cable
from the chassis to inform you of a chassis intru-
sion when the chassis is opened.
