Step 1240-1

1. Ensure that the diagnostics and the operating system are shut down.

2. Power off the system. Refer to "Powering Off the System".

3. Remove and re-install any installed memory module(s).

4. Power on the system. Refer to "Powering On the System".

Does the system stop with a memory checkpoint displayed on the operator panel?

NOReseating the memory modules has corrected the problem.
