Firmware Upgrade through TFTP/HTTP

To upgrade via TFTP or HTTP, the "Firmware Upgrade and Provisioning upgrade via" field needs to
be set to TFTP or HTTP, respectively. "Firmware Server Path" needs to be set to a valid URL of a
TFTP or HTTP server, server name can be in either FQDN or IP address format. Here are examples of
some valid URL.
e.g. firmware.mycompany.com:6688/Grandstream/1.0.8.16
e.g. 168.75.215.189
NOTES:
• TFTP server in IP address format can be configured via IVR. Please refer to section 6.1.3 for
instructions. If TFTP server is in FQDN format, it must be set via web configuration interface.
• Once a "Firmware Server Path" is set, user needs to update the settings and reboot the device.
If the configured firmware server is found and a new code image is available, the HandyTone
ATA will attempt to retrieve the new image files by downloading them into the HandyTone
ATA's SRAM. During this stage, the HandyTone ATA's LEDs will blink 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 fails for any reason (e.g., TFTP/HTTP
server is not responding, there are no code image files available for upgrade, or checksum test
fails, etc), the HandyTone ATA will stop the TFTP/HTTP process and simply boot using the
existing code image in the flash.
• Firmware upgrade may take as long as 1 to 20 minutes over Internet, or just 20+ seconds 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,
Grandstream provides a NAT-friendly TFTP server on the public Internet for firmware
upgrade. Please check the Services section of Grandstream's Web site to obtain our public
TFTP server's IP address.
• Alternatively, user can download a free TFTP or HTTP server and conduct local firmware
upgrade. A free windows version TFTP server is available for download from
http://support.solarwinds.net/updates/New-customerFree.cfm. Our latest official release can be
downloaded from http://www.grandstream.com/y-firmware.htm. Unzip the file and put all of
them under the root directory of the TFTP server. Put the PC running the TFTP server and the
HandyTone ATA in the same LAN segment. Please go to File -> Configure -> Security to
change the TFTP server's default setting from "Receive Only" to "Transmit Only" for the
firmware upgrade. Start the TFTP server, in the HandyTone ATA's web configuration page,
configure the Firmware Server Path with the IP address of the PC, update the change and
reboot the unit. Please be advised that our client will pull out firmware from the WAN side, if
the TFTP server is connected to the device's LAN port, the firmware upgrade will not work by
design.
