Step 1540-7
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 and remove the power cable.
2. Re-install one of the memory modules you installed in the previous step.
3. Plug in the power cable (and wait for OK on the operator panel display).
4. Turn the power on.
Does the system stop with code E1F2, E1F3, STBY or 4BA00830 displayed on
the operator panel?
NO 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 sympton did not change and both memory modules have been
exchanged, go to “Step 1540-8” on page 2-40.
YES Repeat this step with the second memory module you exchanged in the
previous step.
If both memory modules have been tested, go to "MAP 410: Repair
Checkout" in the
