Installing the Motherboard
1. Review the documentation that came with your motherboard. Become familiar
with component placement, requirements, cautions, and cable connections.
2. Power down the system and remove the power cord from the rear of the
power supply as described in Section 5-2. Remove the node from the chas-
sis as described in Section 5-3 and place the node on a flat, stable surface.
Remove the cover from the node as described in Section 5-5.
3. Compare the holes in the motherboard with those in the floor of the node,
then add or remove standoffs as needed.
4. Secure the motherboard to the floor of the node tray using the rounded, Phil-
lips head screws included for this purpose. Do not exceed eight pounds of
torque when tightening down the motherboard.
5. Install the expansion card associated with the motherboard if the chassis is a
hot-swappable version. Refer to the next section for instructions on installing
the expansion card
6. Secure the CPU(s), heatsinks, and other components to the motherboard as
described in the motherboard documentation.
7. Connect the cables between the motherboard, backplane, chassis, front
panel, and power supply, as needed. The fans may be temporarily removed
to allow access to the backplane ports.
8. Replace the expansion card bracket and secure the bracket with a screw.
9. Repeat steps 3 - 5 for the remaining nodes.
