The FRU information for FRU 1 would be FI1A and FI1B or for FRU 2 it would be
FI2A and FI2B, and so forth.
The first part of the FRU information is the unit reference code. Find the reference
codes in the table below to determine the Priority and Location of the failing items.
See the tables in the Locations and addresses topic for the physical mapping of the
information in the Location column.
Each reference code also has an associated Priority Code. The first digit of the
reference code in the table below gives the priority.
v Mandatory priority reference codes start with a 4. You should replace all
mandatory failing items before the next IPL.
v High priority reference codes start with an 8. A FRU with a high priority has a
high probability of resolving the problem. Replace high priority failing items in
order, one at a time with an IPL in between.
v Low priority reference codes start with a C. A FRU with a low priority has a low
probability of resolving the problem. Replace low priority failing items after
replacement of mandatory and high priority items.
The second part of the FRU information is the type number. This will be used in
combination with the Failing Item information to determine the Part Number from
the Type, Model, and Part Number list. If the failing item is given as a Symbolic
FRU, go to the Symbolic FRU topic to determine the failing part. Then go to the
tables in the Locations and Addresses topic for the physical mapping of the
information in the Location column.

If this error occurs at IPL time, clean the cable
connections (if optical), then reseat the cables. If that
does not correct the problem, replace the cable prior to
continuing with the FRU list.
