Connecting Front Panel Components
After the motherboard is installed in the system housing,
you should connect whatever front panel components
the housing has to the Front Panel feature connector on
the motherboard.
The figure below indicates the pin assignments of the
connector for your reference.
EEB 3.0 Housing Installation
If you install the motherboard in an EEB 3.0 system hous-
ing, you should not attach the CPU Backplates. Instead,
attach the board to the housing’s motherboard mounting
plate first. When you do this, the Retention Mechanism
mounting holes should line up with the Retention Mecha-
nism mounting standoffs on the housing’s motherboard
mounting plate. You can then position and install the
Retention Mechanisms by screwing them into the mount-
ing standoffs.
Once you have installed the Retention Mechanisms, you
can proceed to install the Heatsink and Processor Wind
Tunnel assembly as described earlier in this chapter. This
procedure is illustrated in the Xeon processor installa-
tion video mentioned at the beginning of the chapter.
Although the board in the video is not the DP400, the
procedure is the same. Please note that the PWT assem-
bly should be oriented so that the fan blows towards the
rear of the system housing.
