(PCI) Express (PCIe) adapters that are supported for the 8286-41A or 8286-42A system.
PCIe slot descriptions for the 8286-41A and 8286-42A
The 8286-41A and 8286-42A system provides PCIe generation 3 slots. Table 6 provides information about
the PCIe slots in the 8286-41A system that has a single POWER8 processor module and the 8286-42A
system which offers both a single POWER8 processor module or two POWER8 processor modules. The
PCIe slots are enabled to support the PCIe3 cable adapter (FC EJ08) that is used to attach the EMX0 PCIe
Gen3 I/O expansion drawer.
