firewall).
To configure the server path via Web interface:
1. Click Management→ Auto Provision
2. Select the upgrade mode in the Upgrade Mode field
3. Enter the Firmware Server Path and Config Server Path (192.168.0.254 is HTTP server).
4. Enter the HTTP server’s username and password (optional).
5. Click the button to save the configuration.
6. Restart the UC926U, IP Phone will restart and auto-get firmware files from HTTP server.
NOTES:
 Htek recommends end-user use the Htek HTTP server. For large companies, we recommend
maintaining their own TFTP/HTTP/FTP/HTTPS server for upgrade and provisioning
procedures.

Once a “Firmware Server Path” is set, user needs to update the settings and restart the IP
Phone. If the configured firmware server is found and a new code image is available, the
UC926U will attempt to retrieve the new image files by downloading them into the UC926U’s
SDRAM. During this stage, the UC926U’s LEDs will blink fast until the checking/downloading
process is completed. Upon verification of checksum, the new code image will then be saved
into the Flash. If TFTP/HTTP/FTP/HTTPS fails for any reason (e.g. TFTP/HTTP/FTP/HTTPS
server is not responding, there are no code image files available for upgrade, or checksum
test fails, etc), the UC926U will stop the TFTP/HTTP/FTP/HTTPS process and simply boot
using the existing code image in the flash.

Firmware upgrade may take as long as 3 to 8 minutes over Internet, or just 1 minutes if it is
performed on a LAN. It is recommended to conduct firmware upgrade in a controlled LAN
environment if possible. For users who do not have a local firmware upgrade server.
 Htek’s latest firmware is available at www.htek.com→ Support→ Document & Firmware.
 Oversea users are strongly recommended to download the binary files and upgrade firmware
locally in a controlled LAN environment.
To upgrade manually via the Web configuration interface
