IBM iSeries 820 Hardware Problem Analysis And Isolation

3. Is the reference code occurring on a Model 270, 800, 810, 820, or 825 system unit, or an FC 5074,
FC 5075, FC 5078, FC 0578, FC 5079, FC 5088, FC 0588, FC 5094, FC 5095, FC 9074, FC 9079, or
FC 9094 I/O Expansion?
v Yes: Continue with the next step.
v No: See symbolic FRU ACMODUL in the Migrated Expansion Tower Problem Analysis, Repair and
Parts manual on the V5R1 Supplemental Manuals web site . for FRU isolation instructions.
4.
Find the model and or feature code in the table below, then go to the Locations table for the model
you are working on to find the part number and remove and replace procedure information. Note that
on some models and feature codes, “Power PIP11” on page 175 must be performed before replacing
parts.

5. For Models 870/890 with reference code 00AC, if the problem still prevails, perform “MAPPWR-3: An
open room EPO switch has been detected from one side” on page 368.
This
ends the procedure.
ACMODUL instructions for Models 830, 840, SB2, and SB3
Note: The C in the SRC (1xxC xxxx) indicates the problem is on the processor tower side of the Model
840 system type.
1. Is SRC 1xxx 00AC displayed?
v Yes: On the system unit, the 00AC reference code can be caused by an SPCN frame-to-frame
cable problem. This usually occurs between the Model 840/SB3 processor tower and the FC 9079
