The PCIe slot priorities are for the 8286-42A system with two processor modules, while the slot priorities for the 8286-42A system with a single processor module is the same as for the 8286-41A system.
2
The slot is not available to install other adapters in the expanded function system with the FC EJ0Z installed in this slot.
3
The adapters FC 5901 and 5287 are not supported in slots 7, 8, 9, 10, and 11.
4
The adapters FC EJ16, EJ17, and EJ18 are not compatible with the adapters FC EJ12 and EJ13. The FC EJ12 and EJ13 adapters are for gzip compression offload, and the FC EJ16, EJ17 and EJ18 are for
direct-attach fibre channel flash acceleration.
5
The PCIe Cryptographic Coprocessor must not have any other adapter installed in a slot that is adjacent to it for thermal and cooling reasons. Installing an adapter adjacent to the PCIe Cryptographic
Coprocessor invalidates the product warranty.The PCIe Cryptographic Coprocessor can be installed in an end slot, which requires a total of two slots that are adjacent. Otherwise, a total of three slots that are
adjacent is required.
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
(PCI) 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 (FC EMXF or ELMF) installed in the rear of the EMX0 PCIe3 expansion
drawer. Each PCIe3 6-slot fanout module provides six full-length, regular-height, PCIe generation 3 slots.
The PCIe3 slots are compatible with generation 2 or generation 1 PCIe 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 4 on page 33 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 10 on page 33 lists the PCIe adapter slot locations and details for the EMX0 PCIe3 expansion
drawer.
