v Yes: Go to step 8 (See page ).
3. Is the type number from the FRU information zero? Refer to the following:
v For Models 270 and 820: see (B427) System Processor Reference Codes.
v For Models 830, 840, SB2 and SB3: see (B437) System Processor Reference Codes.
– No: Continue with the next step.
– Yes: Go to step 7 (See page ).
4. Use the type number from the FRU information to determine the part number from the Type, model,
and part number list.
5. rom the Type, model, and part locations from the Reference Code Table MB1? No: Continue with the
next step. Yes: The failing item is a backplane. Before exchanging any parts, verify that the
connections to the backplane are secure. Then, choose from the following options: For Models 270
and 820: Continue with the next step. For Models 830, 840, SB2, and SB3: Go to step 11.
6. >11. the FRU locations and failing components table for the system that you are working on to
determine the CCIN and remove and replace procedure for the location specified. Use the
following references:
v For model 270 see Locations: Model 270
v For model 820 see Locations: Model 820
v For models 830 and SB2 see the FRU locations and failing components table in Locations: Models
830, SB2 system unit with FC 9074 base I/O tower.
v For models 840 and SB3 see the FRU locations and failing components table in Locations: Models
840, SB3 system unit processor tower.
Note: If the failing item is a system sub-card, for example, a DIMM on a memory riser card, the
location will have a sub-card letter, for example, M02-A, where M02 is the card slot and A is the
sub-card letter.
This ends the procedure.
7. cedure. "Type number" from the FRU information is zero:
v Use the location information from the reference Code Table to get the FRU name and the physical
mapping information from the Locations and addresses list.

processor feature code.
9. Use the FRU name and, if needed, the processor feature code, to reference the appropriate table
below to determine the type number for the failing item. Then, determine the part number from the
Type, model, and part number list.
10. Go to step (See page )>5.
11. CCINIFMB1" > the part number from the Type, model, and part number list. system a model

v Yes: Continue with the next step.
v No: For Models 830/SB2:
Attention: When replacing the system unit backplane (MB1) on a model 830/SB2, it is required
that the processor cards be replaced also (For additional information, refer to the Model 830/SB2 -
Processor feature codes and CCINs).
Then, continue with step (See page )>6.
12. htm" >Model 830/SB2 - Processor feature codes See the the FRU locations and failing
components table in in the Locations : Models 840, SB3 system unit processor tower for location
MB1 and FRU "System unit backplane" to determine the CCIN and remove and replace procedure.
This ends the procedure.
The following tables are included here:
v Backplane type numbers for Models 270, 820, 830, SB2, 840, and SB3 (See page )
