1. Inspect the Power Plug Connection
   1. Disconnect and reconnect the power plug at the back of the dock.
   2. Ensure the plug fits snugly with firm resistance and minimal wiggle.
   3. If the plug feels loose or unstable, please contact Tech Support. A short video showing the connection may help expedite assistance.
2. Inspect the Wall Connection
   1. Unplug the power brick from the wall outlet.
   2. Check the plug for looseness or instability.
   3. If the dock is under warranty and the plug is faulty, contact Tech Support for warranty work.
3. Check the Power Cable
   1. Trace the power cable from the dock all the way to the wall outlet, check for any nicks, cuts, or kinks.
   2. If any damage is found, the power adapter should be replaced. Note: Physical damage is not covered under warranty, but replacements are available for purchase.
4. Try a Different Outlet
   1. If using a surge protector or UPS, bypass it and plug the power adapter directly into a wall outlet. If the dock works directly in the wall outlet, but not through the surge protector or UPS, please contact the manufacturer of the surge protector or UPS to troubleshoot it.
5. Confirming Dock Functionality Without LED. Even if the LED doesn’t light up, the dock may still be operational. To verify:
   1. Begin by connecting a USB-C, Thunderbolt 3, 4, or 5 cable from the dock’s host port (the front Thunderbolt port with a laptop icon next to it) to the computer.
   2. The System Information application needs to be opened. From Finder, click on the “Go” menu in the menu bar and then select “Utilities.” System Information will be found in the window that opens.
      1. Select Thunderbolt/USB4 from the sidebar.
      2. Look under Thunderbolt Bus for the 11-Port Thunderbolt Dock. If the dock appears in System Information, it is functioning properly and can be used as normal.
   3. If the dock is working but the LED is not and it’s under warranty, you may request warranty work by contacting Tech Support.
   4. If the dock is working but the LED is not and it’s not under warranty, the LED is not serviceable and cannot be repaired or replaced. You can continue using the dock without the LED indicator.

Note: Thunderbolt 3 to Thunderbolt 2 adapters not supported as a host computer connection.
Note: The dock can only be connected to one computer at a time. The rear Thunderbolt (USB-C) ports are for connecting devices, not for host computer connections.

1. Computer to Dock connection confirmation
   
   1. Ensure the dock is connected to the computer via the front Thunderbolt host port, marked with a display icon. This is the designated host port.
2. Check the OWC LED Indicator
   1. No LED = Dock may not be receiving power.
      1. Please follow the steps in the The Dock is Not Powering on (OWC LED not on) section above
   2. Blue LED = Power and active data connection.
      1. The dock should be functioning as normal. If no devices are connected but you want to confirm the dock is recognized:
         1. The System Information application needs to be opened. From Finder, click on the “Go” menu in the menu bar and then select “Utilities.” System Information will be found in the window that opens.
         2. Select "Thunderbolt/USB4" from the sidebar.
         3. Look under "Thunderbolt Bus" for the 11-Port Thunderbolt Dock. If the dock appears in System Information, it is functioning properly and can be used as normal.
         4. If the dock is not seen please skip down to step 3
   3. White LED = Power is connected, but no data connection.
      1. This generally indicates a cable or port issue
3. Try a different known good cable
   1. If the LED is white, test with another known good Thunderbolt or USB-C cable to rule out a faulty connection.
   2. Reset & reconnect
      1. Shut down the computer.
      2. Disconnect all devices from the dock and unplug the power brick from the wall.
      3. Turn the computer on.
      4. Reconnect the dock’s power.
      5. If the LED remains white please contact Tech Support.
4. If you're using an Intel-based Mac, perform an SMC reset and PRAM reset to help resolve hardware detection issues.
5. Test devices one by one. Connect devices to the dock one at a time to identify if a specific item or port is causing the issue.
   1. If a specific device is experiencing an issue, if possible, test it on the other ports on the dock to confirm it is the device and not the individual port
   2. If the specific device is not functioning, please contact the manfacturer of the device for support
   3. If a specific port is not functioning, please contact Tech Support.

If your dock isn’t functioning properly, start by following the steps in the “Dock Not Detected or Fully Functional” section. Once you've confirmed the dock is powered and connected, you can test individual ports and features to isolate the issue.

Test Other Ports - To determine if the issue is limited to a specific port:

1. Use the correct port
   1. Ensure the dock is connected to the computer via the front Thunderbolt host port, marked with a display icon. This is the designated host port.
2. Try connecting common devices like a keyboard, mouse, or external drive to other USB ports.
3. Use known working Thunderbolt or USB-C devices in the dock’s hub ports.
4. If other ports work, the issue may be isolated to one connection. Check below for specific port troubleshooting:

1. Try a different SD card.
   1. If a certain SD card is not working with the dock please contact the manufacturer of the SD card for support.
2. Confirm the card is properly seated.
   1. When inserting the card, it should feel like a gentle resistance, then a smooth, quiet glide until it settles firmly into place.
   2. It should be secure with no wiggle.
   3. If inserting the SD card feels wrong and/or the SD card has an excessive wiggle to it, please contact Tech Support. If possible, please have a video of the issue.
3. The Disk Utility application needs to be opened. From Finder, click on the “Go” menu in the menu bar and then select “Utilities.” Disk Utility will be found in the window that opens.
   1. If available, click on the “View” menu in the menu bar and select “Show All Devices”
   2. Within Disk Utility look to see if the SD card is listed on the left side
   3. If the SD card is not seen within Disk Utility please contact Tech Support.

1. Confirm the ethernet cable is securely connected. Make sure the ethernet cable's locking tab is seated.
2. Try a different Ethernet cable or port on your router.
   
3. If possible, test the dock on another computer
   1. If the dock works on another computer but not on the original, please contact the computer manufacturer for support
4. If possible, use another ethernet adapter to confirm the issue is rooted in the dock
   1. If the connection still has issues with another adapter, please contact your ISP or router manufacturer for additional support.
5. If the issue persists, please contact Tech Support.

1. Open System Preferences by clicking on the Apple menu in the top left corner of the screen and then selecting "System Preferences". Within System Preferences, select "Sound" and confirm that "USB Audio" is selected as the input/output device.
   1. If "USB Audio" is present, make sure the volume sliders are appropriately set.
   2. If "USB Audio" is not present, restart the computer and look again. If "USB Audio" is still not showing up and the dock is under warranty, you may request a return for warranty work
2. If using powered speakers or a microphone, turn the power off and back on the speakers or microphone.
3. Unplug and firmly reseat the audio cable (Note: if using powered speakers, power down the speakers first). When inserting the audio cable there will be a few bumps while inserting, with a final firmer click once fully seated.
   1. Try a different audio cable and/or audio device if available.
      1. If one audio device works while another doesn't, clean the audio cable plug (male plug not the female port on the dock) using a damp (not wet) microfiber towel or cotton swab with 70%+ rubbing alcohol. Let it dry before reconnecting.
   2. If there are no bumps and/or no final click when fully seated, please contact Tech Support. Having a photo or video of the audio cable and insertion process would expedite the troubleshooting.

USB-A Ports - USB-A ports aren’t working:

1. If the device not working is a bus-powered device (no wall power plug) or charger, install the OWC Dock Ejector software.
   1. The Dock Ejector software enables the high power driver so the USB-A ports on the dock provide more power.
2. Test with a simple device like a wired keyboard or mouse.
   1. If a certain device is found to be not working, please contact the device manufacturer for support
   2. If a keyboard and mouse is not working and the dock is under warranty you may request a return for warranty work.
3. For external drives, the Disk Utility application needs to be opened. From Finder, click on the “Go” menu in the menu bar and then select “Utilities.” Disk Utility will be found in the window that opens.
   1. Within Disk Utility, if available, click on the “View” menu in the menu bar and select “Show All Devices.”
