Fan Headers
There are eight fan headers on the
serverboard, all of which are 4-pin
fans (Fan 1-Fan 8). Pins 1-3 of the
fan headers are backward compatible
with the traditional 3-pin fans. (Fan
speed control is supported with 4-pin
fans only.) See the table on the right
for pin definitions. The onboard fan
speeds are controlled by IPMI.
NMI Button
The non-maskable interrupt button
header is located on pins 19 and 20
of JF1. See p. 5-4 and the table on
the right for pin definitions.
