HP Firmware Installer Deployment Reminder
HP Thunderbolt Dock G4 has an enhanced firmware recovery method that can prevent or recover the Firmware of getting
corrupted (for more information See "HP Sure Start for Docks" section in this document).
HP Thunderbolt Dock G4 also adds blinking pattern notifications to let user know when its firmware is getting updated:
as the firmware gets uploaded to the dock then a slow blinking pattern visible on the power button of the dock will occur,
as the firmware starts to get updated in the dock, then the blinking pattern will be faster. Blinking will stop once the upgrade
is completed.
However, most importantly, disconnection during a firmware update can cause damage to the dock. Care must be taken
to ensure that a user does not undock a machine during the firmware installation.
The following two installation options are available with further customization of each available:
Immediate installation of firmware onto the device
This solution requires the device to be connected to the host platform when the installer is executed. HP Firmware
installer will determine which firmware on the device is out of date and flash to the latest. This method can be run
silently, loud, or non-interactively, which shows UI to the user but does not require action.
Staging of firmware onto the host platform
This solution is used to deploy to machines that may or may not be connected to the device at time of installation of the
package. HP Firmware Installer will be installed onto the host platform via Windows Installer same manner as any other
software deliverable. The software installed will also contain the latest firmware binaries. When a compatible device is
connected, the software will determine if a firmware update is needed. When the firmware update is run, a UI is displayed
to the active user inform them of what to expect from the firmware update, as well as give them the option to postpone.
A user must be aware and consent to a firmware update so that they can prevent disconnection of the device during
the update.

HP Thunderbolt Dock G4 Electronic tag (ETag):
Empower your IT to manage and track your docks by product name, serial number, firmware version and MAC Address from
anywhere with the time-saving, easy-to-use Electronic Tag (ETag) asset management tool.
Information in eTag
This information is installed in the Dock during factory process in HP before shipping to customers. The ETag information
contains the following fields:
Serial Number
• Used for asset tracking and tech inventory reconciliation. Availability of this information means saving time
by virtually inventorying docks
Product Name
• Identify which dock IT is managing (ex: HP USB-C® Dock G5 vs. HP USB-C®/A Universal Dock G4). This information
is helpful to customers that own a mixed fleet of docks.
Firmware Package Version
• Used to identify the dock's current firmware version. This is used to determine if a firmware update is needed. In case if
dock support is needed for any issue, firmware version will be useful to HP support in resolving the customer issue.
MAC Address
• Provide a unique hardware address for the dock when connected on a local area network (LAN). This enables
the network security team to take corrective action, if needed.
Gathering ETag
Following methods can be used for ETag collection from the Dock:
- Stand alone script: Microsoft PowerShell scripting is used by most customers versus other scripting tools.
For example: Get-WmiObject -Class HP_DockAccessory -Namespace root/HP/InstrumentedServices/v1 -ComputerName.
- Management Software: Third party solutions can be used to send the script query to the dock in order to collect the ETag
information. This functionality is also part of the HP Manageability Integration Kit.
For more information on how to collecting ETag information from the HP Thunderbolt G4 Dock, please refer to following white
paper HP_Firmware_Installer_for_Docks_L33010-004.pdf under the "WMI Provider" section.
