Grandstream Networks HT502 user manual Http/Https

	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 / HTTPS	The URL for the HTTP/HTTPS server used for firmware upgrade and configuration via
	Server	HTTP.
		For example, http://provisioning.mycompany.com:6688/Grandstream/1.0.0.67“:6688” is
		the specific TCP port where the HTTP or HTTPS 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/HTTPS download once at
		boot up.
