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.

      Installing OWC Innergize

      • Download OWC Innergize application based on the system:
      • Open the downloaded Innergize.dmg file to begin and complete the installation process.
      • For additional information regarding OWC Innergize please consult the support manual "OWC Innergize User Guide"
        NOTE: Only SDXC memory cards are supported with Innergize software through the OWC Thunderbolt Pro Dock.

      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.
      • Windows: Download the required firmware update file “Ethernet Driver for Thunderbolt 3 Pro Dock (Windows)” by visiting the Downloads section of the OWC Thunderbolt 3 Pro Dock Support Guide page.
      • For the best Power Delivery (charging) performance, connect the host computer to the Thunderbolt 3 port labeled ‘60W’. 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.
      • This docking station does not have built-in storage.
      • USB 3.1 Gen 1 ports support UASP for better performance.
      • 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 10G (or other) network via Thunderbolt 3; it does not allow connected devices to function as Network Attached Storage (NAS).
      • The eSATA port supports port multiplier capabilities.
      • This product was designed for use with the fan on and passed engineering tests with the fan on. We have added a switch that can power off the fan when a low-noise environment is needed. However, the device should be used for only short periods of time with the fan in the OFF position. Prolonged use without the fan may cause: the device to overheat; data integrity issues; reduced system stability; longevity issues with various electrical components. We recommend that the device not be used continuously for more than 30 minutes with the fan in the OFF position.
      • The eSATA port and the CFast reader share a single PCIe Gen 2 lane, as do the USB ports and the SD card reader. The maximum transfer rate for a single PCIe Gen 2 lane is about 370MB/s, which means that any device connected to these interfaces cannot go faster than 370 MB/s and when multiple devices are used simultaneously, the bandwidth is shared.
      • The DisplayPort does not support DP++. When using a DisplayPort to HDMI adapter, make sure to use an active adapter.

      Support Resources

      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 Pro 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.
