Find information about the placement rules and slot priorities for the adapters that are supported for the

9040-MR9 system.

Slot descriptions for the 9040-MR9

The 9040-MR9 systems provide PCIe3 and PCIe4 slots. The 9040-MR9 systems offer two or four

POWER9 processor modules. The PCIe slots are enabled to support the PCIe3 cable adapter (FC EJ08 or

FC EJ20) that is used to attach the EMX0 PCIe Gen3 I/O expansion drawer.

Table 2 on page 1 provides information about the PCIe switches in the 9040-MR9 systems.

Two PCIe3 switches (24-port PLX PEX 8725) in the system backplane provide PCIe3 buses from the

system processor modules that provide connectivity to the following features:

• PCIe slots

• PCIe local area network (LAN) controller

• PCIe3 internal SAS controller
