warranty. Read and follow the safety instructions that came with the product.
1 Run the appropriate online diagnostic test. See "Using Dell PowerEdge Diagnostics" on page97.

If an error message does not appear, continue to the next step.
If an error message appears, go to step 11.
3 Enter the System Setup program and check the system memory setting. See "Using the System Setup
Program" on page 27.
If the amount of memory installed matches the system memory setting, go to step 11.
4 Turn off the system and attached peripherals, and disconnect the system from the electrical outlet.
5 Open the system. See "Opening the System" on page 41.
