IBM iSeries 820 Hardware Problem Analysis And Isolation

base I/O tower. See the symbolic FRU “CBLALL” on page 298 for a parts list. If the problem is not
resolved, return here and continue with the next step.
v No: Continue with the next step.
2.
Is the failing AC module on a system unit?
v Yes: Continue with the next step.
v No: Go to step 7 (See page 271).
3. Is the reference code 00AC, CB05, or CB06 on a system with one AC module?
v No: Continue with the next step.
v Yes: Replace the AC module for the Model 840/SB3 processor tower. See Locations - Model 840
for the part number and remove and replace procedure information.
– AC module 1 USA
– World Trade 1 phase
– World Trade 2 phase
– AC line cord
If the reference code prevails - see Symbolic FRU “BKSPCN” on page 286.
This
ends the procedure.
4.
Is the reference code 00AC, 01AC, 02AC, 7410, 7411, 7412, 7413, 7414, 7415, or 7416 on a Model
840/SB3 dual line cord system?
Notes:
a. For reference code 00AC, 01AC, or 02AC, “Power PIP11” on page 175 must be performed before
replacing parts.
b. Check the error log when reference codes 7412 and 7413 are both logged at the same time. If
they are replace - part “CLCKCRD” on page 320
v No: Continue with the next step.
v Yes: Exchange the FRUs listed for the reference codes:
– 01AC, 7410, 7412, 7414, exchange:
- AC module 1 USA
- World Trade 1 phase
- If the reference code prevails, exchange the concurrent maintenance adapter card.
–
02AC, 7411, 7413, 7415, exchange:
- AC module 2 USA
- World Trade 1 phase
- If the reference code prevails, exchange the concurrent maintenance adapter card.
– For 00AC, exchange:
- AC module 1 and 2 USA
- World Trade 1 phase
- If the reference code prevails, exchange the concurrent maintenance adapter card.
– For 7416, exchange:
- Concurrent maintenance adapter card.
- If the reference code prevails, exchange:
v AC module 1 and 2 USA
v World Trade 1 phase
v Clock card - see symbolic FRU “CLCKCRD” on page 320
This
ends the procedure.
5. Is the reference code CC00?
v No: Continue with the next step.
