(The J5000 does not require any DC/DC converter units nor the air dividers.) The DC/DC converter units and air dividers are attached to the J7000 by metal tie-down straps. Each DC/DC converter unit connects to the system board by a 30-pin connector. Removing the DC/DC Converter Units and Air Dividers To remove the DC/DC converter units and air dividers, do the following: 1. Remove the J7000 workstation's top panel and left side panel. 2. On the left side of the workstation, remove the four T-15 Torx screws from the front air divider, and then remove the front air divider. 3. You will see two tie-down straps that are wedged into place over the DC/DC converter units and the rear air divider. One edge of each metal tie-down slips into a slot on the system board fan wall, and the other edge is secured by a T-15 Torx screw on the rear panel of the workstation. Each metal tie-down is also secured to the rear air divider by a T-15 Torx screw. To remove the tie-downs: a. Remove the T-15 Torx screws securing the tie-downs to the rear air divider. b. Remove the T-15 Torx screws from the rear panel of the workstation. c. Swing each tie-down out counter-clockwise. The tab edge will unhinge from the fan wall. 4. Remove the rear air divider. 5. Unscrew the two captive screws on the DC/DC converter unit. 6. Grasp the DC/DC converter unit by the edges and pull it straight out from the system board. The 30-pin connector will release from the system board. Replacing the DC/DC Converter Units and Air Dividers To replace the DC/DC converter units and air dividers, do the following: 1. Remove the J7000 workstation's top panel and left side panel. 2. Perform the previous removal procedure in reverse order. NOTE The two DC/DC converter units are interchangeable. The air flow holes on each unit should face inward to the center of the J7000's system board. Chapter 4 101
