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/1.0.3.64
e.g. 168.75.215.190
NOTES:
1. TFTP server in IP address format can be configured via IVR.
CONFIGURATION GUIDE for instructions. If TFTP server is in FQDN format, it must be set via
web configuration interface.
2. End users recommended using our TFTP server. Its address can be found at
http://grandstream.com/y-firmware.htm. Currently, the TFTP server, your HT-488 can be
upgraded from has an IP address 168.75.215.190. For companies, we recommend to maintain
their own TFTP/ HTTP server for upgrade and provisioning procedures.
3. 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 HT ATA will
attempt to retrieve the new image files by downloading them into the HT ATA's SRAM. During
this stage, the HT 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 HT ATA will stop the
TFTP/HTTP process and simply boot using the existing code image in the flash.
4. 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.
5. Alternatively, user can download a free TFTP or HTTP server and conduct local firmware
upgrade. A free
