This video shows how to install and remove the Thunderbolt3 card On Precision 7865 Tower. Before you begin, turn off the computer, disconnect all the attached peripherals, and remove any SD card installed in the SD card slot on your computer. Ensure that you always use ESD protection when working inside the computer.
To begin, insert the side-cover key and turn the key anti-clockwise to unlock the side cover. Then, push the release latch on the side cover and pull outwards to remove the side cover. Now, let’s install the Thunderbolt3 card. Lay the computer on to its right side. Open the PCIe latch and remove the PCIe filler from the chassis. Align the Thunderbolt3 card with the notch on the system board. Then, insert the Thunderbolt3 card into the PCIe slot on the chassis and close the PCIe latch.
Now, connect the Thunderbolt3 cable to the connector on the system board and then wind the Thunderbolt3 cable around the hook on the chassis. Now, the Thunderbolt3 card installation process is complete. Note, We will demonstrate the side cover installation process once we show the Thunderbolt3 card removal process. To remove the Thunderbolt3 card, unroute the Thunderbolt3 cable from the hook on the chassis.
Then, disconnect the Thunderbolt3 cable from the connector on the system board. Open the PCIe latch and slide the Thunderbolt3 card from the PCIe slot to remove it from the computer. Now align and place the PCIe filler into the PCIe slot and close the PCIe latch. To close the side cover, align the tabs on the side cover with the slots on the chassis, then move it inwards until it clicks in the place.
Insert the side-cover key into the key slot and turn it clockwise to lock the computer. You can now connect all the peripherals. Connect the power adapter and press the power button to power on the computer. For more information or support about Precision 7865 Tower visit Dell.com/Support.
