1. Choose from the following options:
v If you are working from the Service Action Log and a card position is listed with this failing item,
then that is where the error is located. Continue with the next step in this procedure.
v Otherwise, record the bus number value, BBBB, in word 7 of the SRC (see “Breaking down the
SRC” on page 63 for help in determining the bus number). Search for the bus number in HSM or
the System Configuration Listing to determine which tower contains the failing item.
2.
The failing component is built into the backplane of the FC 5075 expansion I/O tower. Use the table
below to determine the service information for the failing component.
Expansion I/O tower Name of FRU to exchange Link to failing component service information (CCIN,
PN, remove and replace procedure)
FC 5075 Tower card See the Locations - 5075 topic
FC 5095 Tower card See the Locations - FC 5095 topic
This ends the procedure.
TWRCARD
For use by authorized service providers.
An SPCN card may be failing. The SPCN card may be on the backplane, on a card, or part of the AC
module in some of the system expansions. See the Remove and replace procedures for the model you
are working on before exchanging the SPCN.
Perform the following to determine the part number:
1. Verify that all cables are seated correctly.
2. Choose from the following options:
v If you are on a Model 270 or 820: Continue with the next step.
v If you are on a Model 830, 840, SB2, or SB3: Go to step 5 (See page 471).
v If you are on a Model 800, 810, 825, 870, or 890: Go to step 7 (See page 472).
3.
Is the failing SPCN card in the system unit?
v No: Continue with the next step.
v Yes: The TWRCARD is the system unit backplane (MB1). Replace:
– Model 270 without removable processor as installed:
- (MB1) - (CCIN 224A)
- (MB1) [no cache] - (CCIN 25B9)
- (MB1) [2M] - (CCIN 25BA)
–
Model 270 with removable processor (MB1) - (CCIN 282F)
– Model 820 (MB1) - (CCIN 282D)
Note: See symbolic FRU “CCIN” on page 303 for the correct part. For location information, see
Locations and addresses for the model you are working on.
This ends the procedure.
4.
The failing SPCN card is in a secondary expansion unit or base I/O unit.
Note: For migrated towers (FC 5033, FC 5034, FC 5035, FC 5065, FC 5066, FC 5072, FC 5082, FC
5073, FC 5083, and FC 5077), see chapter 4 in Migrated Expansion Tower Problem Analysis, Repair
and Parts manual on the V5R1 Supplemental Manuals web site
for remove and replace
procedures before exchanging the part.
v For FC 5033, FC 5034, and FC 5035, the SPCN card is part of SPNLCARD, and is the card located
behind the control panel. See Type, model, and part number list for the part number.
