Step 1240-11
The memory module(s) (may be both) you exchanged in the previous step may be
defective. To isolate the failing memory module, do the following:
1. Turn the power off.
2. Re-install one of the memory modules you exchanged in the previous step.
3. Turn the power on.
Does the system stop with a memory checkpoint displayed on the operator
panel?
NO Repeat this step with the second memory module you exchanged in the
previous step.
If both memory modules have been tested go to "Map 0410: Repair
Checkout" in the
IBM RS/6000 Diagnostic Information for Multiple Bus
Systems
.
YES Replace the memory module.
If you have not tested both memory modules repeat this step with the
second memory module you exchanged in the previous step.
If the symptom did not change and both memory modules have been
exchanged, go to “Step 1240-10” on page 2-21.
