The USB cable or the USB connection between the I/O adapter (IOA) and the device might be failing.
For more information about failing part numbers, location codes, or removal and replacement procedures, see Part locations and location codes. Select your machine type and model number to see applicable procedures for your system.
Complete the following steps:
- Is a location code available in the serviceable event view for
this field-replaceable unit (FRU)?
- Yes: Determine the location of the port by removing -Lx from the location code. Replace any USB cables or extension cables at the port location. If there are no USB cables or extension cables, replace any hardware that connects the IOA to the device. Then, continue with step 3.
- No: Continue with the next step.
- Use the USB_DEV symbolic FRU to determine the location of the USB port that the external USB device is attached to. Replace any USB cables or extension cables at the port location. If there are no USB cables or extension cables, replace any hardware that connects the IOA to the device. Then, continue with the next step.
- Has the problem been resolved?
- Yes: This ends the procedure.
- No: Continue with the next step.
- Is the system a 9080-MHE, 9080-MME,
9119-MHE, or 9119-MME, or is the
problem in an EMX0 PCIe3 expansion drawer?
- Yes: Continue with the next failing item in the failing item list. This ends the procedure.
- No: Continue with the next step.
- Use the following table to determine the internal USB cable that
might be failing. Ensure that the cables are connected correctly.
If they are not connected correctly, fix the cable connection problem.
If they are already connected correctly, replace the cables.
