Other checkpoints may take up to 3 minutes to assure stability, depending on system configuration. Does the operator panel stabilize with code E1F2, E1F3, E1F7, or STBY? NO Go to "Step 1540-5" on page 2-22. YES Repeat this step until all the memory DIMMs are installed and tested. After all the memory DIMMs are installed and tested, record the positions of the memory DIMMs in the second memory card. Remove all of the memory DIMMs from the second memory card except 1 pair. Repeat this step with the second memory card (if previously installed). Go to "Step 1540-7" on page 2-24. Chapter 2. Maintenance Analysis Procedures 2-21
