Notes:
1. To determine the failing items, go to “Failing Items” on page 479.
2. To determine the associated part numbers, go to “Type, Model, and Part
Number list” on page 885.
3. To determine the parts associated with symbolic FRUs, such as “ANYBUS”,or
“DEVTERM”,goto“Symbolic FRUs” on page 495.

(283C, 283D, 283F) Device Backplane Reference Codes
1. 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.
2. 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.
4. The 673x is a read cache. Perform all actions required for 673x as a disk drive
and logic card except where separate 673x cache instructions are provided.
