General Use Precautions

  • Read this user guide carefully and follow all recommended usage steps and precautions.
  • To avoid damage, do not expose the device to temperatures outside the following ranges:
    • Environmental (Operating)
      • Temperature (ºF): 41º — 95º
      • Temperature (ºC): 5º — 35º
    • Environmental (Non-Operating)
      • Temperature (ºF): -4º — 140º
      • Temperature (ºC): -20º — 60º
  • Always unplug the device from the electrical outlet if there is a risk of lightning or if it will be unused for an extended period of time. Otherwise, there is an increased risk of electrical shock, short-circuiting or fire.
  • Do not use the device near other electrical appliances such as televisions, radios or speakers. Doing so may cause interference which will adversely affect the operation of the other products.
  • Protect your device from excessive exposure to dust during use or storage. Dust can build up inside the device, increasing the risk of damage or malfunction.
  • Do not block any ventilation openings on the device. These help to keep the device cool during operation. Blocking the ventilation openings may cause damage to the device and cause an increased risk of short circuiting or fire.

Safety Precautions

  • Read this user guide carefully and follow the recommended steps for assembly.
  • Use proper anti-static precautions while installing drives into this enclosure. Failure to do so can cause damage to your drive mechanisms and/or the enclosure.
  • Do not attempt to disassemble or modify the device. To avoid any risk of electrical shock, fire, short-circuiting or dangerous emissions, never insert any metallic object into the device. If it appears to be malfunctioning, please contact technical support.
  • Never expose your device to rain, or use it near water or in damp or wet conditions. Never place objects containing liquids on the drive, as they may spill into its openings. Doing so increases the risk of electrical shock, short-circuiting, fire or personal injury.

        3.2 OWC Innergize Software

        A software application included with OWC Atlas media cards that currently provides three basic functionalities to the user: Health, Sanitize and Field Firmware Upgradability.

        • The Health function allows the user to know how much life is left on their OWC Atlas media card
        • Sanitize removes ghost data on OWC Atlas media cards which will allow the media cards to perform at their peak and out of factory condition performance in matter of seconds
        • Field Firmware upgradability allows OWC to deliver live updates to our memory cards without the hassle of sending them in for an update.

        3.3 Usage Notes

        • Mac: To enable support for the Apple Super Drive, Apple USB Keyboard, and charging for iPad 1/2/3 generation devices on the dock’s ‘high-power’ ports, please install the Dock Ejector application for Mac. This application includes a driver that enables support for these devices and charging functions. go.owcdigital.com/dockejector
        • Windows: A driver is required for Windows users. Downloaded the required driver by visiting: www.marvell.com/support/downloads.html#. Instructions for downloading the driver are located in section 2.2 "Device Drivers".
        • For the best Power Delivery (charging) performance, connect the host computer to the Thunderbolt port labeled '90W’ located on the side of the device. This should be sufficient to charge applicable 15-inch MacBook Pro models that come with an 87W power supply, when the dock is the only thing connected to the host. When you have peripherals connected to both the dock and the host, it may not charge as expected, depending on the configuration.
        • With a USB host (such as an USB-C equipped MacBook, iPad, Chromebook, Android device, or PC), this device works as a USB hub. Bandwidth is reduced to USB speeds, Thunderbolt devices are not supported, and additional functionality will vary depending upon the host port's capabilities.
          • With a USB-C host, displays and power delivery support will depend upon the host port's capabilities.
          • With a USB-A host, displays and power delivery are not supported. Requires a USB-C to USB-A adapter (available separately).
        • Recommended performance of 2.5Gb/s Ethernet requires compatible hardware components and cabling (i.e. Cat 5e cable minimum, Cat 6 or later strongly recommended). Components that aren’t rated at 2.5Gb/s Ethernet speed will reduce the system’s Ethernet performance while connected to the Thunderbolt Go Dock (i.e. 1Gb/s).
        • This docking station does not have built-in storage.
        • SD cards inserted into the OWC Thunderbolt Go Dock will not be recognized by Windows Disk Management or applications after being safely removed. Power cycle the entire OWC Thunderbolt Go Dock by disconnecting the power source. This will allow the OWC Thunderbolt Go Dock to create a new card session resulting in Windows recognizing the SD card.
        • It is not possible to access data on connected drives through the Ethernet interface. The network interface behaves like a network adapter that allows you to connect your computer to a 10Gb (or other) network via Thunderbolt; it does not allow connected devices to function as Network Attached Storage (NAS).
        • Thunderbolt 2/Thunderbolt compatibility requires a certified Thunderbolt 3 (USB-C) to Thunderbolt 2 (mDP) adapter and a Thunderbolt 2 cable (available separately). This configuration provides data transfer at up to 20Gb/s) but does not support notebook charging.
        • Router and/or Network Switch must support AVB.
        • Actual display support varies upon computer specifications. Supported Intel-based Apple Mac models and Thunderbolt 4 PCs support two displays over a Thunderbolt port. Apple silicon M1 and M2 Mac models support a single display over a Thunderbolt port.

            4.1 Troubleshooting

            • Begin by verifying that the power cable and brick connections are all secure. Then verify that the Thunderbolt cable is connected to the OWC Thunderbolt Go Dock. Next, verify the other end of the Thunderbolt cable is properly plugged into a system. If issues persists, try connecting a different Thunderbolt cable and see if the OWC Thunderbolt Pro Dock works properly. Connecting to a different system is also an option to verify the issue.
            • If issues continue to occur, please know that OWC support is here to help. Contacting support information can be found in section 4.4 "Contacting Support". Please have your serial number ready which is located on the bottom of the OWC Thunderbolt Pro Dock and printed on the original packaging.
