Product Information Internal Components DC/DC Converter Units and Air Dividers (J7000 Only) The J7000 has two DC/DC converter units, which provide DC/DC conversion for the workstation, and two air dividers on its left side. (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. (In the previous Figure 1-13, the air dividers and the metal tie-down straps have been removed so only the DC/DC converter units are shown.) Each DC/DC converter unit connects to the system board by a 30-pin connector. Note that both of the DC/DC converter units are interchangeable, and that the air flow holes on each unit are facing inward to the center of the J7000's system board. System Board Cooling Fans There are three system board cooling fans in three separate mounting brackets on the front, left side of the J5000 and J7000 workstations. These fans draw air flow from the front of the workstation inward to cool the system board. Internal Components on the Right Side As you face the J5000 and J7000 workstation, the internal components on the right side of the workstations include the power supply, I/O board, SCA (Single Connector Attach) hard disk interface (also known as the backplane board), I/O cooling fan, and speaker. Figure 1-14 shows the internal components located on the right side of both the J5000 and J7000 workstation. (In this figure, the right side panel has been removed from the workstation so that the internal components can be viewed. Also note that the J5000 and J7000 have different power supplies; however, their power supplies look the same.) Figure 1-14.
