DRWRMID

To determine the location of the midplane, complete the following steps:

1. Is a location code available in the serviceable event view for this failing item?
   • Yes: Continue with the next step.
   • No: Go to step 3.
2. The location code in the serviceable event view is either a PCIe3 cable adapter in the system unit or the midplane in an EMX0 PCIe3 expansion drawer. For information about locations, see Part locations and location codes. Is the location code in the serviceable event view the location of a PCIe3 cable adapter in the system unit?
   • Yes: Go to step 4 to find the location of the midplane.
   • No: Go to step 5 to replace the midplane at this location.
3. To determine the location of the failing item, complete the following steps:
   1. Record the dynamic reconfiguration connector (DRC) index, which is word 7 of the B700xxxx reference code.
   2. The DRC index is of the form xxxxyyyy, where yyyy is the hexadecimal bus number. Using the hexadecimal bus number, go to Card positions to find the location of the PCIe3 cable adapter that is attached to the EMX0 PCIe3 expansion drawer that contains the failing item. Then, continue with the next step.
4. Trace the expansion drawer cable from the PCIe3 cable adapter that was identified in the previous step to find the EMX0 PCIe3 expansion drawer that contains the failing item. Then, use the table in step 6 to find the location of the failing midplane within the EMX0 PCIe3 expansion drawer. After you find the location of the failing midplane, continue with the next step.
5. Is the system managed by a management console?
   • Yes: Use the management console to replace the failing item at the location that was identified in this procedure.
   • No: Continue with the next step.
6. Use the following table to determine the service action to perform.

   Type and model	Part number	Description	Location code	Service action
   EMX0 PCIe3 expansion drawer	See System parts.	Midplane	Un-P3	Replace the midplane at the location that was identified in this procedure. For more information about EMX0 PCIe3 expansion drawer location codes and removal and replacement procedures, see EMX0 PCIe Gen3 I/O expansion drawer locations.

This ends the procedure.
