2. Check compatibility of node board ports and I/O shield:
Note: Make sure that the I/O ports on the node boards align properly with their respective
holes in the I/O shield on the back of the SGI Altix XE320 chassis.
3. Remove the PCI card riser card and bracket.
4. Mount the node board onto the node board tray:
a. Carefully mount the node boards by aligning the board holes with the raised metal
standoffs that are visible in the chassis (refer to Figure 4-2).

will damage the equipment.
b. Install the six screws into the mounting holes on the node board that line up with the
standoffs and tighten until snug. The metal screws provide an electrical contact to the
node board ground to provide a continuous ground for the system.
5. Install the PCI riser card and bracket.
A node board has two 20-pin ATX power supply connectors (refer to Figure 4-2) that can be
connected to the ATX power supply. Only one of these connectors is used when the node board
is installed in the chassis. Each node board also provide a 4-pin auxiliary power connector used to
connect disk drive power to the SATA backplane.
For the node board 1 (installed on the left side of the chassis):
1. Connect the power cable to the primary ATX power header on the right side of the node
board.
2. Connect the auxiliary power cable to the power connector on left side of the SATA
backplane.
