Firmware Upgrade
and Provisioning
and Provisioning
Enables HT502 to download firmware or configuration file through either the TFTP or
HTTP server.
HTTP server.
Via TFTP Server
This is the IP address of the configured TFTP server. If selected and it is non-zero or not
blank, the HT502 retrieves the new configuration file or new code image from the
specified TFTP server at boot time. After 5 attempts, the system will timeout and will start
the boot process using the existing code image in the Flash memory. If a TFTP server is
configured and a new code image is retrieved, the new downloaded image is saved into
the Flash memory.
Note: Please do NOT interrupt the TFTP upgrade process (especially the power supply)
as this will damage the device. Depending on the local network, this process can take up
to 15 or 20 minutes.

Via HTTP Server
The URL for the HTTP server used for firmware upgrade and configuration via HTTP.
For example, ttp://provisioning.mycompany.com:6688/Grandstream/1.0.0.67“:6688” is the
specific TCP port where the HTTP server is listening; it can be omitted if using default port
80.
Note: If Auto Upgrade is set to No, HT502 will only do HTTP download once at boot up.
