(2765, 2766) Reference Codes
If the error is reported on the control panel, the unit reference code is characters 5
through 8 of the top 16 character line of function 11. If the error is reported on the
console, the unit reference code is the 4 rightmost characters of word 1.
Find the unit reference code in the following table.
Notes:
1. If the failing item is a failing item (FI) code, go to “Failing Items” on page 479
to determine which part number associated with the FI code is failing.
2. If the failing item is a type number, go to “Type, Model, and Part Number list”
on page 885 to determine the part number.
3. If the failing item is a symbolic FRU, go to “Symbolic FRUs” on page 495 to
determine the part number.
