EMX0 PCIe Gen3 I/O expansion drawer addresses

You can cross-reference a PCIe adapter physical location code to the address.

PCIe3 4-slot direct module addresses

Use the direct select address (DSA) to find the location for the system, and then go to EMX0 PCIe Gen3 I/O expansion drawer locations to find additional location information.

Table 1. Address information for the PCIe3 4-slot direct module in a EMX0 PCIe Gen3 I/O expansion drawer
Physical location code Possible failing item Cable port locations on the I/O module
Un-Py-C1 PCIe adapter Un-Py-T1, Un-Py-T2
Un-Py-C2 PCIe adapter Un-Py-T3, Un-Py-T4
Un-Py-C3 PCIe adapter Un-Py-T5, Un-Py-T6
Un-Py-C4 PCIe adapter Un-Py-T7, Un-Py-T8
The physical location code is Un -Py -Cx. To determine whether Py is P1 or P2, and whether Cx is C1, C2, C3, or C4, complete the following steps:
  1. The hexadecimal IOA card bus number is the four leftmost digits of the DSA. Convert the hexadecimal IOA card bus number into a hexadecimal PCIe3 optical cable adapter bus number by removing the first and last digits of the IOA card bus number. For example, if the IOA card bus number is 0100, then the PCIe3 optical cable adapter bus number is 10.
  2. Go to Card positions, find the table for your system unit, and use the hexadecimal PCIe3 optical cable adapter bus number to look up the location of the cable adapter.
  3. Trace the cables from the cable adapter in the system unit to the I/O module in the EMX0 PCIe Gen3 I/O expansion drawer. If the cables are attached to the I/O module on the left side, the location is P1. If the cables are attached to the I/O module on the right side, the location is P2.
  4. Using the cable port locations identified in step 3, go to Table 1 and determine the Cx value of the IOA card.

PCIe3 6-slot fanout module addresses

Use the direct select address (DSA) to find the location for the system, and then go to EMX0 PCIe Gen3 I/O expansion drawer locations to find additional location information.

Physical location code Possible failing item DSA (BBBBCcbb) Unit address
Un-Py-C1 PCIe adapter 0xx1xxxx Not applicable
Un-Py-C2 PCIe adapter 0xx2xxxx Not applicable
Un-Py-C3 PCIe adapter 0xx3xxxx Not applicable
Un-Py-C4 PCIe adapter 0xx4xxxx Not applicable
Un-Py-C5 PCIe adapter 0xx5xxxx Not applicable
Un-Py-C6 PCIe adapter 0xx6xxxx Not applicable
To determine if Py is P1 or P2, complete the following steps:
  1. The hexadecimal IOA card bus number is the four leftmost digits of the DSA. Convert the hexadecimal IOA card bus number into a hexadecimal PCIe3 optical cable adapter bus number by removing the first and last digits of the IOA card bus number. For example, if the IOA card bus number is 0102, then the PCIe3 optical cable adapter bus number is 10.
  2. Go to Card positions, find the table for your system unit, and use the hexadecimal PCIe3 optical cable adapter bus number to look up the location of the cable adapter.
  3. Trace the cables from the cable adapter in the system unit to the I/O module in the EMX0 PCIe Gen3 I/O expansion drawer. The I/O module on the left side is P1. The I/O module on the right side is P2.
