Frequently asked questions1. The fan is not working after connecting with the system.• The fan is triggered by temperature. The dock fan will not rotate until the dock is hot enough to trigger a thermal threshold.• Vice versa, if your dock is not cool enough, the fan will not stop even when you disconnect the dock from the system.2. The dock does not work after high-speed fan noise.• When you hear a loud fan noise, it is warning you that the dock is in some kind of a hot condition. For example, the vent in the dockmay be blocked or the dock is working in a high working-temperature environment (> 35C), etc,. Please eliminate these abnormalconditions from the dock. If you do not eliminate the abnormal condition, in a worst-case situation, the dock will shut down throughthe over-temperature protection mechanism. Once this happens, please un-plug the Type-C cable from the system and removethe dock’s power. Then wait 15 seconds and plug in the dock power to recover the dock back online.3. I hear a fan noise when I plug in the dock’s AC adapter.• This is a normal condition. First time plugging in of the dock’s AC adapter will trigger the fan to rotate, but it will subsequently turnoff very soon.4. I hear a loud fan noise. What’s wrong?• The dock fan is designed with five different rotate speeds. Normally, the dock will work on low fan speed. If you put the dock in aheavy loading, or in a high working-temperature environment, the dock fan may have a chance to work at a high speed. But, this isnormal and the fan will work at a low/high speed depending on the work loading.Table 16.

What is the charging station feature?• The Dell Thunderbolt Docking Station WD19TB can charge your mobile or power bank even without being connected to thesystem. Just make sure your dock is connected to external power. The dock fan will rotate automatically if the dock gets toowarm. This is normal working condition.6. Why am I asked to approve Thunderbolt Devices after the Windows logon and what should I do?• This is for Thunderbolt security. You are asked to approve a Thunderbolt device because the Thunderbolt Security level on yourunit is set to “User Authorization” or “Secure Connect” in the BIOS Setup. You will not see this page if the Thunderbolt Securitylevel on your system is set to “No Security” or “DisplayPort Only”. Also, if you checked “Enable Thunderbolt Boot Support” in theBIOS Setup and power-on the system with the WD19TB dock attached, you will not see this page because the Security level isoverridden to “No Security” in this case. When you are asked to approve a Thunderbolt device, you may select “Always Connect” ifyou do not have any security concerns to always allow the Thunderbolt device connection to your system. Or you may select“Connect Only Once” or “Do Not Connect” if you do have concerns.7. Why does it take a long time for the system to recognize all the peripheral devices which are attached to the dockingstation?• Security is always Dell’s highest priority. We ship our systems with “Security level - User Authorization” setting by default. Thisallows our customers to review the Thunderbolt security conditions of their systems so they can make selections accordingly.However, this also means the Thunderbolt dock and the devices attached to it will need to pass Thunderbolt driver securitypermission checking to get it connected and initialized. This normally means some extra time is needed before these devices canbe accessed by users.8. Why does the hardware installation window show up when I plug in a USB device to the docking stations ports?12Frequently asked questions 35
