v Yes: The book just reinserted is defective. Replace it. Return the system to its original
configuration. See Verify the repair.
This ends the procedure.
v No: Continue with the next step.
11. Have all the books listed in step 4 (See page 382) been reinserted?
v Yes: The symptom has changed. Return the system to its original configuration. See Verify the
repair.
This ends the procedure.
v No: Go to step 8 (See page 382).
12. Power off the system. See Power on/off the system and logical partitions. Then, examine the amber
logic-power LEDs of all installed processor subsystem DCAs.
13. Are all amber logic-power LEDs of all installed processor subsystem DCAs off?
v Yes: Continue with the next step.
v No: Replace the DCA that has the amber logic power LED that did not turn off. See symbolic FRU
"DCAPWR" on page 324.
14. Pull out the following books about 25 mm (1 inch), if present:
v Memory book 4 at location M25
v Memory book 5 at location M08
v Memory book 6 at location M01
v Memory book 7 at location M17
15. Power on the system. See Power on/off the system and logical partitions.
16. Did the system stop with the same error code as recorded in step 1 (See page 382)?
v Yes: Go to step 22 (See page 383).
v No: Continue with the next step.
17. One of the books just removed is defective.
a. Power off the system. See Power on/off the system and logical partitions.
b. Make sure all amber logic-power LEDs of all installed processor subsystem DCAs are off.
18. Reinsert one of the books that is pulled out and listed in step 14 (See page 383).
19. Power on the system. See Power on/off the system and logical partitions.
20. Did the system stop with the same error code as recorded in step 1 (See page 382)?
v Yes: The book just reinserted is defective. Replace it. Return the system to its original
configuration. See Verify the repair.
This ends the procedure.
v No: Continue with the next step.
21. Have all the books listed in step 14 (See page 383) been reinserted?
v Yes: The symptom has changed. Return the system to its original configuration. See Verify the
repair.
This ends the procedure.
v No: Go to step 18 (See page 383).
22. Power off the system. See Power on/off the system and logical partitions. Then, examine the amber
logic-power LEDs of all installed processor subsystem DCAs.
23. Are all amber logic-power LEDs of all installed processor subsystem DCAs off?
v Yes: Continue with the next step.
v No: Replace the DCA that has the amber logic power LED that did not turn off. See symbolic FRU
"DCAPWR" on page 324.
24. Pull out the following cards or books about 25 mm (1 inch), if present:
v Secondary network interface controller (NIC) card at location M30
