Step 1. Align the system board with the rails in the compute tray; then, insert the system board, making
sure that the rails on the board fit into the slots in the compute tray.
Step 2. Slide the system board into the compute tray until the release clips snap into the locked position.
Step 3. Connect all cables on the system board that go to connectors in the compute tray. See “Internal
cable routing” on page 35.
After you install the system board:
• If you installed the lower system board in a compute tray, slide the upper system board or filler back into
the compute tray until the release clips snap into the locked position.
