Thunderbolt Configuration
If Dell BIOS is used in your system, you may find below Control options in Thunderbolt™ Configuration page in your BIOS Setup:
1 Enable Thunderbolt™ Technology Support (Enabled by default)
• When enabled, the Thunderbolt™ Technology feature, and associated ports and adapters are enabled.
• When disabled, the Thunderbolt™ Technology feature is disabled, and any connected Thunderbolt™ adapter devices are not
available in pre-boot or within the operating system.
2 Enable Thunderbolt™ Boot Support (Disabled by default)
• When enabled, the following Thunderbolt™ adapter features are enabled during Pre-boot: Thunderbolt™ adapter boot support,
USB device on Thunderbolt™ adapter support (including USB boot support). This allows Thunderbolt™ adapter peripheral
devices and USB devices connected to the Thunderbolt™ adapter to be used during BIOS pre-boot. However, setting this to
“Enabled” will override the Security Levels utilized within the operating system. When this setting is enabled, any Thunderbolt™
adapter peripherals and USB devices connected to the Thunderbolt™ adapter port prior to booting the system can be used in
pre-boot. As long as the device remains connected, it will continue to function within the operating system, regardless of the
Security Level set in BIOS.
3 Enable Thunderbolt™ Adapter Pre-boot Modules (Disabled by default)
• When enabled, this setting will allow PCIe devices that are connected through a Thunderbolt™ adapter (i.e. PCIe devices behind
the Thunderbolt™ adapter) to execute the PCIe device’s UEFI Option ROM(s) (if present) during pre-boot.
• When disabled, this setting will prevent PCIe device Option ROMs from executing during pre-boot for PCIe devices connected
behind the Thunderbolt™ adapter.
NOTE: Enabling the “Enable Thunderbolt™ Adapter Boot Support“ or “Enable Thunderbolt™ Adapter Pre-boot Modules“ options
may allow devices connected to the Thunderbolt™ adapter during pre-boot to function in the operating system regardless of the
Security Level selected in BIOS Setup. The device will continue to operate in the operating system until it is disconnected. When
reconnected while within the operating system, the device will connect according to the Security Level and previous OS
authorizations.
16 Thunderbolt Settings and Security Options
Page: 16
Thunderbolt Security
The settings below configure the Thunderbolt™ adapter security settings within the operating system. Security Levels are not applicable
or enforced in the Pre-boot environment.
• No Security: Automatically connect to devices plugged into the Thunderbolt™ port.
• User Authorization: Approval is required for any new devices connected to the Thunderbolt™ port.
• Secure Connect: The Thunderbolt™ adapter port will only allow connection to devices that have been configured with a shared key.
NOTE: The first time a Thunderbolt peripheral’s Unique ID is granted “always connect” PCIe access, a secure encrypted
key is written to the peripheral controller’s non-volatile memory and added to the host PC’s ACL list. Each time a
peripheral’s Unique ID is found on the ACL, the PC’s controller sends a security challenge and the response from the
peripheral is then verified before the PCIe connection is allowed. If the response is not valid, the user receives a
connection permission prompt. This capability, when enabled, prevents pre-SL2 capable peripherals from connecting to a
PC; thereby preventing a potential HW spoofing of an approved device to generate a DMA exploit (beyond what is
prevented with SL1).
• DisplayPort Only: Automatically connect to DisplayPort devices only. No Thunderbolt™ adapter or PCIe devices are allowed to
connect.
In the BIOS of a Dell Thunderbolt-enabled PC, you will be able to configure the security settings of the Thunderbolt connection. You can
find the configuration options in the BIOS path: System Configuration > USB / Thunderbolt Configuration.
No security Allow legacy Thunderbolt devices to auto-connect – the CM auto
connects a new device plugged in.
User Authorization Allow User Notification devices at minimum –the CM requests
connection approval from the host SW and auto-approval may be
given based on the Unique ID of the connecting device.
Secure Connect Allow one-time saved key devices at minimum – the CM requests
connection approval from the host SW and auto-approval is only
given if the host challenge to the device is acceptable.
DisplayPort Only Allow DisplayPort sinks to be connected (re-driver or DP tunnel, no
PCIe tunneling).

Frequently asked questions
1 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
dock may be blocked or the dock is working in a high working-temperature environment (> 35C), etc. Please eliminate these
abnormal conditions from the dock. If you do not eliminate the abnormal condition, in a worst-case situation, the dock will shut
down through the over-temperature protection mechanism. Once this happens, please un-plug the Type-C cable from the
system and remove dock’s power. Then, 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 turn
off very soon.
4 I hear a loud fan noise. What’s wrong?
• The dock fan is designed with two different rotate speeds. Normally, the dock will work on low fan speed. If you put the dock in a
heavy loading, or in high working-temperature environment, the dock fan may have a chance to work at a high speed. But, this is
normal and the fan will work at a low/high speed depending on the work loading.
5 What is the charging station feature?
• The Dell Thunderbolt Dock TB16 can charge your mobile or power bank even without being connected to the system. Just make
sure your dock is connected with external power. The dock fan will rotate automatically if the dock gets too warm. 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 your
unit is set to “User Authorization” or “Secure Connect” in the BIOS Setup. You will not see this page if the Thunderbolt Security
level on your system is set to “No Security” or “DisplayPort Only”. Also, if you checked “Enable Thunderbolt Boot Support” in the
BIOS Setup and power-on the system with TB16 attached, you will not see this page because the Security level is overridden to
“No Security” in this case. When you are asked to approve a Thunderbolt device, you may select “Always Connect” if you 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 docking station?
• Security is always Dell’s highest priority. We ship our systems with “Security level - User Authorization” setting by default. This
allows 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 security
permission checking to get it connected and initialized. This normally means some extra time is needed before these devices can
be accessed by users.
8 Why does the hardware installation window show up when I plug in a USB device to the docking stations ports?
• When a new device is plugged in, the USB hub driver notifies the Plug and Play (PnP) manager that a new device was detected.
The PnP manager queries the hub driver for all of the device's hardware IDs and then notifies Windows OS that a new device
needs to be installed. In this scenario, the user will see a hardware installation window.
https://msdn.microsoft.com/en-us/windows/hardware/drivers/install/step-1--the-new-device-is-identified
https://msdn.microsoft.com/en-us/windows/hardware/drivers/install/identifiers-for-usb-devices
9 Why do the peripheral devices, which are connected to the dock station, become unresponsive after recovering from a power
loss?
• Our Thunderbolt dock is designed to operate in AC only and it does not support system power source back (powered by system
type-C port). A power loss event will make all devices on the dock fail to work. Even when you restore the AC power, the dock
may still not function properly because the dock still needs to negotiate proper power contract with the system Type-C port and
establish a system EC-to-dock-EC connection. A Type-C cable re-plug is needed to initiate the power contract negotiation and
establish system EC-to-dock-EC virtual I2C connection. As a result, after a power loss, the user needs to unplug type-C cable, re-
plug in AC power, and then re-plug-in Type-C cable to system to restore dock back to normal condition.
