To update the software via the interface (HTTP), first, upload the appropriate driver from our "drivers" section.

Then go to "System menu" >> "Firmware" tab >> "Upload source" >> "From local filesystem" >> "Select file". 

Select the driver upgrade file and press "OK".  After the update is complete the web interface displays the message "Firmware Upload".

Upgrade files may have different names:

• vutlan-2.x.x-bxxx.vut - to update the driver for VT3xx, VT6xx, VT805, VT825 units;

• firmware-kernel.vut - to update the kernel driver on VT3xx, VT6xx, VT805, and VT825 units;

• vutlan-vt900-3.x.x-bxxx.vut - to update the driver for VT9xx units;

• vutlan-vt960i-4.x.x-bxxx.vut - to update the driver for VT960i & VT960ii units;

• vutlan-vt855i-5.x.x-bxxx.vut - to update the driver for VT335i, VT825i, and VT855i units.

The updating process is indicated by LEDs on the front panel of the device: file installation is indicated by switching ERR, and the end of the installation process is indicated by a short-term increase in switching frequency ACT. Then all the lights switch off - the system is rebooted. Completion is indicated by switching to reboot ACT.

The update duration is approximately 2 minutes. After the reboot (all LEDs are turned off) after 30-60 seconds, check the system operation.
