Infi niBand Connection
Both the X9DRT-IBQF and
X9DRT-IBFF serverboards have an
onboard Infi niBand (IB) connector,
which is located on the rear IO panel
on the serverboard. The IB switch is
primarily used for High-performance
computing. See the table on the right
for pin defi nitions.

Fan Headers
This serverboard has three system/CPU
fan headers (Fan 1, Fan 3, and Fan 4)
on the serverboard. All these 4-pin fans
headers are backward compatible with
the traditional 3-pin fans. The fan speeds
are controlled by fi rmware management
via IPMI interface. See the table on the
right for pin defi nitions.
