ia TFTP Serve
r
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.
