|WAN||eth0||RJ45 1000/100/10 Mbit/s|
|LAN||eth1||RJ45 1000/100/10 Mbit/s|
|SFP||eth2||SFP 1000 Mbit/s|
The RJ45 ports support Autonegotiation and Full Duplex or Half Duplex on all speeds.
The SFP Port supports the following Modules:
- 1GB BaseT/SR/LR/CR
There is no vendor lock for SFP modules. You can use any Module that conforms to the standard.
The VT AIR 100 has 1 power connector:
- 9 - 32VDC 5.5mm x 2.5 mm cylindrical barrel connector
9 - 32VDC barrel connector
A suitable external power supply must be connected to the DC power socket, which has the dimensions 5.5 mm x 2.1 mm cylindrical
barrel connector. The power supply must be between 9 and 32VDC. Recommended values are: 12VDC/2A (no more than 5A).
Please note that the DC jack must have positive polarity in the center pin:
Please be aware that the maximum temperature for the barrel connector is 40°C.
2.1.6. USB Console¶
The appliance has a UART to USB bridge allowing convenient connection to the device console.
Such serial console connection is of USB-to-UART type. The connection speed should be set to 115200 bps.
All modern Operating Systems have a driver for the UART.
First you have to locate the COM Port number.
Open the Device Manager and expand the section for Ports (COM & LPT). Look for an entry with a title such as USB Serial Port. A label is next to the name (COMX) where X is a number.
In OSX the device shows up at /dev/tty.usbserial-XXXXXX where X is a series of numbers and letters.
In Linux the device shows up at /dev/ttyUSBX where X is a number. You can also have a look at the output of dmesg to locate the newly connected device.
A terminal program is required to open the connected serial port. We recommend:
2.1.7. VT AIR Reinstallation¶
Your VT AIR device comes pre-installed with its operating system. Should you ever need to reinstall the OS though you can download it from your Portal (see Downloads for details). Make sure to download the file for your specific model/architecture.
22.214.171.124. USB key preparation¶
Once downloaded transfer the ISO file to a USB key using either the tools provided by your computer’s OS (macOS, Linux) or a specific program like LinuxLive USB Creator (Windows). Make sure your USB key is empty before using it since it will be formatted in the process and it’s at least 2 GB in size.
Start LinuxLive USB Creator and choose the USB key that you want to use for the installation. Click ISO and select the file that you downloaded from the Portal. Then click the lightning icon. The software will format your USB key and write all the data to it. Once it is finished you can unplug the USB key and close the prgram.
Use the command
to see all connected drives. search for your USB key and note its name (e.g. /dev/sdb).
Eject the disk
sudo umount /dev/sdX
and write the data to the USB key
sudo dd bs=4M if=path/to/file.iso of=/dev/sdX conv=fdatasync status=progress
with path/to/file.iso being the downloaded OS file and /dev/sdX being the usb key (e.g. /dev/sdb). Be very careful with this since this command wipes all data of the drive. Make sure to select the correct /dev/sdX!
Wait for the command to finish and eject the USB key.
Use the command
to see all connected drives. search for your USB key and note its name (e.g. /dev/disk2).
Eject the disk
sudo umount /dev/diskX
and write the data to the USB key
sudo dd bs=4m if=path/to/file.iso of=/dev/diskX conv=fdatasync status=progress
with path/to/file.iso being the downloaded OS file and /dev/diskX being the usb key (e.g. /dev/disk2). Be very careful with this since this command wipes all data of the drive. Make sure to select the correct /dev/sdX!
Wait for the command to finish and eject the USB key.
126.96.36.199.4. USB Key¶
Insert the USB key with the new OS in your VT AIR’s USB port.
188.8.131.52. Serial Console Installation¶
Connect the USB cable to the Console USB port of your VT AIR device and your computer. On your computer connect to your VT AIR’s Console (see Console Access).
Type “reboot” to reboot the system. In the boot process you’ll see a timer that you can interrupt by pressing any key. This gives you a shell from where you can reinstall your OS.
Type “run install” to run the OS installer from your USB stick. The installer runs without any user inputs.
The VT AIR 100 has multiple LEDs. They are indicating for example power on, connection and port activity. Ethernet port related LEDs are embedded in the RJ45 connectors, while the power indicator LED is located next the serial port.
The RJ45 NIC LEDs are configured the following way:
|Green Light Only||100Mbit/s Speed|
|Green and Yellow Light||1000Mbit/s Speed|
2.1.9. Operational Data¶
|Front barrel connector||9 - 32 VDC||2.0 A||Max. 35°C|
The environmental temperature data are based upon the component with the lowest available temperature. Please make sure to check which addons you ordered and make sure not to exceed the allowed ambient temperature.
Failure to comply with the allowed ambient temperature may void the warranty of your device.
|Humidity (non-condensing)||10 %||90 %|
Leave a minimum of 2cm of space on both sides of the device.
For ambient temperatures above 30°C, leave 5cm space on both sides of the device for air cooling to work properly.

AC/DC Adapter or Power Supply - Electrical Safety
The following information on electrical safety must be observed, failing to follow these instructions may result in electric shock, fire and/or serious personal injury or death.
Use only the adapter or power supply supplied with the product or adapter or power supply with the following specifications:
- Output voltage of 9V - 32V and current of at least 2A and not more than 3A
Prior to powering the product and plugging the adapter or power supply to the mains supply, always ensure that the nominal voltage setting on the adapter or power supply matches the nominal voltage of the AC supply network.
If extension cords or connector strips are implemented, they must be checked on a regular basis to ensure that they are safe to use.
Never use the adapter or power supply if the power cable is damaged. Check the power cable on a regular basis to ensure that it is in proper operating condition. By taking appropriate safety measures and carefully laying the power cable, you can ensure that the cable will not be damaged and that no one can be hurt by, for example, tripping over the cable or suffering an electric shock.
Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and all the way into the socket. Otherwise, sparks that result in fire and/or injuries may occur.
Do not overload any sockets, extension cords or connector strips; doing so can cause fire or electric shocks.
Do not insert or remove the plug with wet hands.
Never remove the cover or any part of the housing of the adapter or power supply, doing so will expose circuits and components and can lead to electric shock, injuries, fire or damage to the product.
The adapter or power supply operating ambient temperature range is of 0 to 40°C / 32 to 104 °F (storage temp range: -20 to 60 °C / -04 to 140 °F) maximum operating altitude is 2000 m ASL.
Use suitable overvoltage protection to ensure that no overvoltage (such as that caused by a bolt of lightning) can reach the product. Otherwise, the person operating the product will be exposed to the danger of an electric shock.
The product is not liquid proof; therefore, the equipment must be protected against penetration by liquids. If the necessary precautions are not taken, the user may suffer electric shock or the product itself may be damaged, which can also lead to personal injury.
Never use the product under conditions in which condensation has formed or can form in or on the product, e.g. if the product has been moved from a cold to a warm environment. Penetration by water increases the risk of electric shock.
Prior to cleaning the product, disconnect it completely from the power supply. Use a soft, non-linting cloth to clean the product. Never use chemical cleaning agents such as alcohol, acetone or diluents for cellulose lacquers.
