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 “Locations and Addresses” on page 705 for the physical mapping of the
information in the Location column.
Note: The priorities are:
v Mandatory: You should replace all mandatory failing items before the
next IPL.
v High:This part 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: This part 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.
v If the failing item is given as a FI code, go to “Failing Items” on page 479.
Determine the part number that is associated with the failing FI code.
v If the failing item is given as a Symbolic FRU, go to “Symbolic FRUs” on
page 495 to determine the part number.
