An I/O module provides slots 6 to 8.
An I/O module supports 2-slot PCIe riser module or 3-slot PCIe riser module, but three slots
are always displayed on the panel. For a 2-slot PCIe riser module, slot 8 is unavailable.
Table 2-2 describes the mapping between PCIe devices and CPUs, and the PCIe
specifications of the 5288 V3.
NOTE
The PCIe devices mapping to a vacant CPU socket are unavailable.
