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 adapters that are supported for the
EMX0 PCIe Gen3 I/O expansion drawer (EMX0 PCIe3 expansion drawer).
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 cable adapter in the system.
Figure 2 on page 5 shows the rear view of the EMX0 PCIe3 expansion drawer with the location codes
for the adapter slots in the PCIe3 6-slot fanout module.
Table 4 on page 6 lists the adapter slot locations and details for the EMX0 PCIe3 expansion drawer.
Note:
The left I/O module bay is configured with the first PCIe3 6-slot fanout module slot location codes
P1-C1 through P1-C6.
The right I/O module bay is configured with the second PCIe3 6-slot fanout module slot location codes
P2-C1 through P2-C6.
