Table 2 on page 2 provides information about the PCIe slots in the 8247-21L system that has a singlePOWER8 processor module, the 8247-22L system that has two POWER8 processor modules, and the8284-22A that offers both a single POWER8 processor module or two POWER8 processor modules. ThePCIe slots are enabled to support the PCIe3 cable adapter (FC EJ05) that is used to attach the EMX0 PCIeGen3 I/O expansion drawer.© Copyright IBM Corp. 2014, 2017 1
