MEXIP03

Use this procedure to isolate a power problem with an I/O module in an EMX0 PCIe3 expansion drawer.

1. Is a location code in the format Un-Px available in the serviceable event view for the reference code you are working on?
   • Yes: Continue with the next step.
   • No: Contact your next level of support. This ends the procedure.
2. Use the location to find the EMX0 PCIe3 expansion drawer. For information about locations, see Part locations and location codes. Ensure that there is power to the EMX0 PCIe3 expansion drawer by verifying the following LED states:
   • The ac input LED (A) and the dc output LED (B) are on solid for at least one of the power supplies in the EMX0 PCIe3 expansion drawer. See figure 1.
   • The I/O module power LED (C) is on solid. The power LED is located below the expansion drawer cable ports on the I/O module that was identified in the previous step. For the location of the Power LED on a PCIe3 6-slot fanout module, see figure 2.

   Were any power LED problems detected?

   • Yes: Ensure that the EMX0 PCIe3 expansion drawer has power. If the EMX0 PCIe3 expansion drawer has power, complete the replacement procedure for any FRU with a power LED problem. For more information about EMX0 PCIe3 expansion drawer location codes and removal and replacement procedures, see EMX0 PCIe Gen3 I/O expansion drawer locations. For more information about EMX0 PCIe3 expansion drawer part numbers, see EMX0 PCIe Gen3 I/O expansion drawer system parts. This ends the procedure.
   • No: Continue with the next step.
3. Are there any 1000xxxx reference codes in the serviceable event view that have the EMX0 PCIe3 expansion drawer that contains the I/O module identified in step 1 in the failing item list?
   • Yes: Complete the service actions that are indicated for the reference code. This ends the procedure.
   • No: Continue with the next failing item in the failing item list of the serviceable event. This ends the procedure.
