Chapter 5. Error Code to FRU Index
The Error Code to FRU Index lists error symptoms and possible causes. The most
likely cause is listed first. Use this index to help you decide which FRUs to replace
when you are servicing the system.
Performing Slow Boot
To fully analyze all of the available information, perform the following steps before
continuing or doing a hardware repair or replacement, especially if the error is related to
the CPU or memory:
1. Record the 8-character error code (and location code if present) displayed in the
operator panel or that was reported by the customer.
2. Do a slow-mode boot in service mode. This can be specified using the System
Power Control Menu on the service processor main menu. (A fast-mode boot skips
much of the built-in diagnostic testing.) A slow-mode boot may yield a new
8-character error code on the operator panel and new errors in the service
processor error log. If a new error code is reported, use it in subsequent steps to
continue problem analysis. If a new error code is not reported, continue with the old
error code.
Considerations for Using the Error Code to FRU Index
If you replace FRUs or perform an action and the problem is still not corrected, go to
"MAP 1540: Minimum Configuration" on page 59, unless otherwise indicated in the
tables.
If you replace FRUs or perform an action and the problem is corrected, go to "MAP
0410: Repair Checkout" in the RS/6000 Eserver pSeries Diagnostic Information for
Multiple Bus Systems .
If the codes in the following tables indicate a device that is present more than once in
the system unit, a location code is needed to specify which device generated the error.
Go to "Step 1020-4" on page 44 to display the System Management Services error log
and obtain a location code. Location code descriptions can be found under "Location
Codes" on page 11.
After you have obtained the location code, see Chapter 10, "Parts Information" on
page 293 for the part number.
Notes:
1. If more than eight digits are displayed in the operator panel, use only the first eight
digits to find the error in the tables. The digits that display beyond the first eight
digits are location codes that can assist you in diagnosing the problem. See
"Location Codes" on page 11.
2. Licensed programs frequently rely on system information stored on the VPD on the
operator panel control assembly. If the MAPs indicate that the operator panel control
