RIOIP12

Use this procedure to recover from a B7xx 6985 high speed link (HSL) failure.

1. Work with the customer to determine if a system or I/O unit on the RIO loop has powered down normally.
2. Was a system or I/O unit on the loop powered down normally?
   • No: Go to 4.
   • Yes: The loop remains in a failed state until all systems and I/O units on the loop are powered on and functioning. Work with the customer to determine if all the powered down systems and units on the loop can be powered on. After all system and units on the loop are powered on, check to determine if the RIO loop is complete. To determine if the RIO/HSL loop has recovered, record the RIO/HSL loop number in the first four characters of word 7 of this SRC and perform RIOIP10.
3. Did the RIO loop recover?
   • No: Continue with the next step.
   • Yes: Close the problem. This ends the procedure.
4. In the serviceable event view, search for a B700 6981 or a B700 6986 error logged at approximately the same time and on the same RIO loop (the first four characters of word 7 are the same).
5. Did you find a serviceable event with a 1xxx xxxx SRC?
   • No: Go to 7
   • Yes: Work that problem. After you have repaired that error, the RIO/HSL loop may be recovered. After you complete working that problem, return to this procedure and check to determine if correcting that problem also corrected the RIO/HSL error. To determine if the HSL/RIO loop has recovered, record the RIO/HSL loop number in the first four characters of word 7 of this SRC and perform RIOIP10.
6. Did the RIO loop recover?
   • No: Continue with the next step.
   • Yes: Close the problem. This ends the procedure.
7. In the serviceable event view, search for a B700 6981 or B700 6986 error logged at approximately the same time and on the same RIO loop (the first four characters of word 7 are the same).
8. Did you find a B700 6981 or a B700 6986 error logged at approximately the same time and on the same RIO loop?
   • No: Go to 10.
   • Yes: Work that problem. After you have repaired that error, the RIO/HSL loop may be recovered. After you complete working that problem, return to this procedure and check to determine if correcting that problem also corrected the RIO/HSL error. To determine if the RIO/HSL loop has recovered, record the RIO/HSL loop number in the first four characters of word 7 of this SRC and perform RIOIP10.
9. Did the RIO loop recover?
   • No: Continue with the next step.
   • Yes: Close the problem. This ends the procedure.
10. Search for a system or IO unit on the RIO loop that has not powered up as expected.
11. Did you find a system or IO unit on the RIO loop that has not powered up as expected?
    • No: Go to 13.
    • Yes: Go to Cannot power on SPCN-controlled I/O expansion unit and work that power symptom. Use the first half of word 7 to determine the loop number for later use. After you have repaired that error, the RIO/HSL loop may be recovered. After you complete working that power symptom, return to this procedure and check to determine if correcting that problem also corrected the RIO/HSL error. To determine if the RIO/HSL loop has recovered, record the RIO/HSL loop number in the first four characters of word 7 of this SRC and perform RIOIP10.
12. Did the RIO loop recover?
    • No: Continue with the next step.
    • Yes: Close the problem. This ends the procedure.
13. Using the FRU list that you are working with for this SRC, exchange one FRU at a time. After you exchange each FRU, determine if the loop has recovered. To determine if the RIO/HSL loop has recovered, record the RIO/HSL loop number in the first four characters of word 7 of this SRC and perform RIOIP10. After the loop recovers or after you have exchanged all the FRUs, continue with the next step.
14. Did the RIO loop recover?
    • No: Contact your next level of support. This ends the procedure.
    • Yes: Close the problem. This ends the procedure.
