The PCIe Expansion Node has four slots that support optional PCIe adapters.
The adapter slots are located in two PCIe riser assemblies that provide a mechanical structure to support the PCIe adapters and connect the adapters to the system board.
The full-height PCIe adapter slots are located on the left side of the expansion node and are numbered 1 (lower slot) and 2 (upper slot). The low-profile PCIe adapter slots are located on the right side of the expansion node and are numbered 3 (lower slot) and 4 (upper slot).
The following illustration shows the PCIe Expansion Node adapter slot numbers.
The full-height and low-profile PCIe risers plug into connectors on the PCIe Expansion Node system board. The system board also has two standard 2x3, six-pin auxiliary power connectors to support PCIe adapters that require additional dc power. See System board connectors for the location of the PCIe riser and auxiliary power connectors.
For a list of supported optional devices, see the IBM ServerProven website for your compute nodes machine type and model number.
For current information about the PCIe adapters that are available for your compute node, see the Network devices information page.
Full-height PCIe adapter slots
The full-height PCIe adapter slots accept full-height full-length, full-height half-length, and low-profile PCIe adapters (when the low-profile adapters are using a full height spine).
The following illustration shows the location of the full-height PCIe adapter slots.
Low-profile PCIe adapter slots
The low-profile adapter slots accept low-profile PCIe adapters only.
The following illustration shows the location of the low-profile PCIe adapter slots.
