Fan Headers

The server board provides five SSI-compliant 4-pin fan headers to be used as the CPU and
chassis. The pin configuration for each of the 4-pin fan headers is identical and defined in the
following table:

One 4-pin fan headers are designated as processor cooling fans:
o CPU fan (J5J1 on S1200BTL and J4J1 on S1200BTS)
o SYS1 fan (J1J4 on S1200BTL and J7J1 on S1200BTS)
o SYS2 fan (J5J2 on S1200BTL and J7B1 on S1200BTS)
o SYS3 fan (J7J1 on S1200BTL and J2J1 on S1200BTS)
o SYS4 fan (J7B1 for S1200BTL)
