IBM iSeries 820 Hardware Problem Analysis And Isolation

v No: Continue with the next step.
v Yes: Perform one of the following to isolate the failing item:
– “Power PIP4” on page 153 for Models 800 and 810
– “Power PIP5” on page 158 for Model 825
6.
Is the SRC 1xxx 2605 or 1xxx 2606?
v No: This ends the procedure.
v Yes: Perform one of the following to isolate the failing item:
– “Power PIP6” on page 160 for an FC 5074, FC 5079, FC 5094, FC 8093, FC 8094 or FC 9094
– “Power PIP9” on page 172 if the fault is in an FC 5075, FC 5085, FC 5095 or FC 0595 I/O tower,
or an FC 7116 system expansion unit
– “Power PIP8” on page 168 for an FC 5078, FC 0578, FC 5088, or FC 0588
Instructions for Models 830, 840, SB2, and SB3
When referenced, perform the Power PIPs in each step before exchanging parts.
1. Is the SRC 1xxx 2221 or 2321?
v No: Continue with the next step.
v Yes: The backplane card may be the failing item. See symbolic FRU “BACKPLN” on page 284 to
exchange the failing item. Also see Locations and addresses for the model you are working on. If
the error did not go away, exchange the cable between the panel and the card, part 44H8022 or
44H8017. See Locations and addresses.
This ends the procedure.
2. Is the SRC 1xxx 2222, 2223, 2322 or 2323?
v No: Continue with the next step.
v Yes: See tower card (“TWRCARD” on page 470) only for these SRCs.
3. Is the SRC 1xxx 2224 or 2324?
v Yes: Continue with the next step.
v No: Go to step 5 (See page 413).
4. Are you working on a unit with a SPD card enclosure with the 2735 card installed correctly?
v No: Exchange the following parts one at a time:
– PCI I/O card - part 45H1235 (see Locations and addresses).
– The cable between the SP/PCI I/O card and the PCI I/O card - part 44H8038 (see Locations
and addresses).
– The SP/PCI/ I/O card - part 45H1226 (see Locations and addresses).
This
ends the procedure.
v Yes: Exchange the following parts one at a time:
– 2735 optical Bus IOP - part 44H7791
– SPD backplane - part 44H7994
This
ends the procedure.
5. Perform the following:
a. Power off the expansion frame.
b. Check that the tower card is connected and seated properly. See symbolic FRU “TWRCARD” on
page 470.
c. Check that the power supplies are connected and seated properly. See symbolic FRU
“PWRSPLY” on page 431.
d. Power on the expansion frame.
Is there an SRC 1xxx 2600 or 2601?
