Card positions

The following information correlates PCI bus numbers to PCI card location codes for the listed machine types and models.

PCI bus numbers in system units are assigned as indicated in the following tables. PCI bus numbers in expansion units are assigned by Licensed Internal Code or firmware as the buses are discovered.

Bus number (hexadecimal) Item that is designated by the bus number Location
xx1 PCIe3 x16 adapter Un-Py-C1
xx2 PCIe3 x8 adapter Un-Py-C2
xx3 PCIe3 x8 adapter Un-Py-C3
xx4 PCIe3 x16 adapter Un-Py-C4

xx6 PCIe3 x8 adapter Un-Py-C6
Note: To determine whether Py is P1 or P2, complete the following steps:
  1. Convert the hexadecimal adapter bus number into a hexadecimal PCIe3 cable adapter bus number by removing the last digit of the bus number. For example, if the adapter bus number is 102, then the PCIe3 cable adapter bus number is 10.
  2. Find the hexadecimal PCIe3 cable adapter bus number in the appropriate system unit table to determine the location of the PCIe3 cable adapter.
  3. Trace the cables from the PCIe3 cable adapter in the system unit to the I/O module in the EMX0 PCIe3 expansion drawer. The I/O module on the left side is P1. The I/O module on the right side is P2.
