Pcie Adapter Placement Rules And Slot Priorities For The Emx0 Pcie Gen3 I/O Expansion Drawer - IBM Power System 9009-42A Manual

PCIe adapter placement rules and slot priorities for the EMX0 PCIe Gen3 I/O
expansion drawer
Find information about the placement rules and slot priorities for the Peripheral Component Interconnect
Express (PCIe) adapters that are supported for the EMX0 PCIe Gen3 I/O expansion drawer (EMX0 PCIe3
expansion drawer).
PCIe slot descriptions for the EMX0 PCIe3 expansion drawer
The number of PCIe slots that are provided in the EMX0 PCIe3 expansion drawer depends on the I/O
module configuration of the EMX0 PCIe3 expansion drawer. Your configuration might have one or two
PCIe3 6-slot fanout modules installed in the rear of the EMX0 PCIe3 expansion drawer. Each PCIe3 6-slot
fanout module provides six full-length, full-height, PCIe3 slots. The PCIe3 slots are compatible with
PCIe1 and PCIe2 adapters. The PCIe slots use generation 3, single-wide, blind-swap cassettes.
The I/O module in the EMX0 PCIe3 expansion drawer is connected to the system with an expansion
drawer cable pair. Each cable pair must be the same length and are attached to the T1 and T2 ports in the
I/O module and to the corresponding ports in the PCIe3 cable adapter in the system.
Figure 2 on page 9 shows the rear view of the EMX0 PCIe3 expansion drawer with the location codes
for the PCIe adapter slots in the PCIe3 6-slot fanout module.
Table 6 on page 9 lists the PCIe adapter slot locations and details for the EMX0 PCIe3 expansion
drawer.
