Step 1540-13
Look at the FRU part numbers associated with the SRN.
Have you exchanged all the FRUs that correspond to the failing function
codes?
NO Exchange the FRU with the highest failure percentage that has not been
changed.
Repeat this step until all the FRUs associated with the SRN have been
exchanged or diagnostics run with no trouble found. Run diagnostics after
each FRU is exchanged.
If the I/O planar or a network adapter is replaced, see notes on page 2-1.
Go to "MAP 410: Repair Checkout" in the IBM RS/6000 Diagnostic
Information for Multiple Bus Systems.
YES If the symptom did not change and all the FRUs have been exchanged,
call your service support person for assistance.
