Fan Headers
The workstation board provides four SSI-compliant 4-pin and four SSI-compliant 6-pin fan
headers to be used as CPU, and I/O cooling fans.
3-pin fans are supported on all fan headers. 6-pin fans are supported on headers J3H4, J3H3,
J3H2, and J3H1.
4-pin fans are supported on headers J9J1, J5J1, J3H4, J3H3, J9B4, and J9B3. 4-pin fans are
not supported on headers J3H2 and J3H1, since these headers are tied to the CPU1 PWM. Do
not use these fan headers for CPU cooling fans. The pin configuration for each of the 4-pin and
6-pin fan headers is identical and is defined in tables below.
Two 4-pin fan headers are designated as processor cooling fans:
o CPU1 fan (J9J1)
o CPU2 fan (J5J1)
Four 6-pin fan headers are designated as hot-swap system fans:
o Hot-swap system fan 1 (J3H4)
o Hot-swap system fan 2 (J3H3)
o Hot-swap system fan 3 (J3H2)
o Hot-swap system fan 4 (J3H1)
Two 4-pin fan headers are designated as rear system fans:
o System fan 5 (J9B4)
o System fan 6 (J9B3)
