The PCIe Expansion Node and a compute node host are assembled using a 2-bay shelf that attaches to the bottom of each node.
The 2-bay shelf has two retention latches located near the center
of the shelf and four alignment posts, one on each of the shelf corners.
The PCIe Expansion Node and
the host compute node are placed onto the alignment posts; then, pushed
toward the center of the shelf to latch the units in place.
- The compute node is placed on the left side of the shelf and pushed right toward the center to latch the unit in place.
- The PCIe Expansion Node is placed on the right side of the shelf and pushed left toward the center of the shelf to latch the PCIe Expansion Node in place.
The 2-bay shelf assembly fits onto the shelf supports inside the Flex System Enterprise Chassis and requires the existing 1-bay shelf to be removed prior to installation.
The following illustration shows the 2-bay shelf.
See Attaching the PCIe Expansion Node to a compute node host for procedures to attach an expansion node and a compute node to a 2-bay shelf.
