FSPSP37 instructions for Model 590

1. Determine which node on the system has the problem by performing the following:
   1. Power off the system (see Powering on and powering off).
   2. Replace one of the nodes.
   3. Performing a slow boot.
   4. Does the problem persist?
      • No: The node you just replaced is causing the problem. Go to step 3.
      • Yes: Continue with the next step.
2. Have you tried replacing all of the nodes?
   • No: Repeat step 1 and replace the next node.
   • Yes: Replace the system backplane using symbolic FRU isolates/frusysbkpl.dita#frusysbkpl. This ends the procedure.
3. Determine what part in the failing node is causing the problem by performing the following:
   1. Power off the system (see Powering on and powering off).
   2. Replace the RIO/HSL adapter card using symbolic FRU isolates/frusicard.dita#frusicard.
   3. Reinstall the failing node.
   4. Perform a slow boot.
   5. Does the problem persist?
      • No: This ends the procedure.
      • Yes: Continue with the next step.
4. Perform the following:
   1. Power off the system (see Powering on and powering off).
   2. Replace one of the system processors on the failing node using symbolic FRU isolates/fruanyproc.dita#fruanyproc.
   3. Perform a slow boot.
   4. Does the problem persist?
      • No: This ends the procedure.
      • Yes: Continue with the next step.
5. Have you replaced all of the system processors on the failing node?
   • No: Repeat step 4 and replace the next processor.
   • Yes: Perform the following:
     1. Power off the system (see Powering on and powering off).
     2. Replace the failing node backplane using symbolic FRU isolates/frunodepl.dita#frunodepl.
     3. Perform a slow boot. This ends the procedure.
