Remove the top panel and the left side panel of the workstation. 2. Fold back all fan cables and the ribbon cable for the power switch/LCD assembly to avoid interference and damage while inserting the system board tray assembly into the workstation. 3. Hold the system board tray assembly vertical to the workstation floor and align the holes in the tray assembly to the right of the sheet metal hooks on the workstation's center wall. 4. Carefully slide the system board tray assembly to the left to engage the center wall hooks. Inspect to ensure that all hooks are engaged in the holes of the system board tray assembly. 5. Insert and tighten the T-15 Torx screws that secure the system board tray assembly to the rear panel of the workstation. 6. Connect the three fan cables and the ribbon cable for the power switch/LCD assembly to the system board. Refer to Figures 4-24 and 4-25 on the previous two pages. You should also pull the J7000 workstation's fan cables through the system board's tray handle for clearance. 7.
