* BIOS update files for the Intel NUC can be found [here](https://downloadcenter.intel.com/search?keyword=bios+nuc).
* ASUS NUC documentation and BIOS updates can be found on the [ASUS support site](https://www.asus.com/support/).
* Check that the display (monitor) used with the NUC are compatible. Check on the hardware documentation. To verify, power up the NUC with the monitor connected, if the manufacturer splash screen can be seen, the monitor is compatible.
* On the NUC, check that the BIOS version is current. If not the most current, upgrade to the latest version.
* The appliance is intended to the an always-on device. Verify that the following is set in the BIOS:
  * After Power Failure setting should be set to Last State or Power On.

## Installing Physical Appliance Software

1. Verify that the installation environment requirements are satisfied.
2. Insert the bootable USB disk in one of the USB slots on the NUC.
3. Power up the NUC.
4. Tap the **F10** key (on the keyboard) to force the BIOS to enter the "Boot" menu.
5. On the boot device menu, use the arrow keys to select the USB drive and press **Enter**.

If USB is not shown as an option, power off the NUC, unplug the USB drive, plug it back in and power up the NUC.

**Note:** The BIOS will recognize the USB drive as a bootable device even if the USB flash drive is blank (nothing in it). If the BIOS does not recognize the USB drive as a valid bootable device, when there is a USB flash drive inserted, check that the BIOS version is current. If not current upgrade to the latest version.

6. On booting from the USB drive, the installation process will start automatically. `No` user intervention is required, The initial phase will progress fairly quickly, a progress bar will narrate the progress. The final phase is shown by the "Finishing the installation" screen, "Running preseed," the progress bar will show "14%." The installation process are downloading the required software packages. This screen may remain in this state for about 15 minutes, depending on the speed of the network interface and the delays to the download server. Do not power off the NUC. Leave it until it automatically powers off.
7. On completing the installation, the NUC will automatically power off.
8. Remove the installation USB.

   If you don't remove it once the installation is complete, the NUC attempts to boot again, restarting the installation process.

## Configuring the Enterprise Agent

See [How to Set Up the Virtual Appliance](https://docs.thousandeyes.com/product-documentation/enterprise-agents/how-to-set-up-the-virtual-appliance) for a comprehensive set of instructions. The following are the minimum required to enable the Physical Agent to communicate with the ThousandEyes platform.

1. Power on the NUC. After the unit boots, the "ThousandEyes Virtual Appliance" screen (shown below) will be displayed. The IP address displayed depends on the network environment of the NUC. Note the provided username and password.

5. For information on the other parameters, see [How to Set Up the Virtual Appliance](https://docs.thousandeyes.com/product-documentation/enterprise-agents/how-to-set-up-the-virtual-appliance).
6. Verify on the **Status** screen that all diagnostics are green. Follow up and correct any faults shown on the Status screen.

![](/files/-M62_RBx7jaE-CGt-ao3)

7. If network related parameters were changed, for example disabling IP V6 support, reboot the Agent, through the GUI and verify that all the diagnostics are green.

![](/files/-M62_RC07aaDn-zkxJFJ)

8. The Enterprise Agent should now appear in the **Cloud & Enterprise Agents> Agent Settings> Enterprise Agents** page of the ThousandEyes portal.

## Troubleshooting

#### USB Drive Not Recognized as a Bootable Device

A USB drive is plugged in, tapping F10 at power-up, on the "Boot" BIOS screen, USB drive is not recognized as a bootable device.

**Resolution:** Check that the BIOS version is current. If not current, upgrade to the latest version.

#### Malformed IP Address

Ubuntu installation fails with a "blue screen" showing "Malformed IP Address."

**Resolution:** Verify that the Ethernet connection to the NUC has a link signal. Verify that the Link LED on the RJ-45 port is lit.\
Verify that there is a DHCP server on the network (broadcast domain) that the NUC is connected to.

#### No Root File System Defined

Ubuntu installation fails with "No Root File System Defined" message. This situation can occur if USB devices are attached to the NUC via a USB hub.

**Resolution:** Do not use USB hub to connect keyboard and USB flash drive to the NUC.

#### "thousandeyes-va login:" Prompt Is Shown on the Screen

The expected blue "ThousandEyes Virtual Appliance" management screen is not displayed. Instead, a black screen with "`thousandeyes-va login:"` prompt is shown.

This is a symptom of an unsuccessful installation. The agent is missing the **te-pa** package which, in addition to the web admin interface, provides the physical console functionality.

**Resolution:** Components of the Virtual Agent are missing. Most likely caused by the lack of non-proxied and unrestricted access to the internet during the appliance installation. Reinstall the appliance in an environment that satisfies the requirements listed in the installation environment requirements.

#### Keyboard Not Working

When the installation completes, keypresses are not recognized.

**Resolution:** Most likely incomplete installation. Reinstall the appliance in an environment that satisfies the requirements listed in the installation environment requirements.
