HandyTone-286 User Manual Grandstream Sdn Bhd
To configure the TFTP server via the Web configuration interface, open up your
browser to point at the IP address of the HandyTone ATA. Input the admin
password to enter the configuration screen. From there, enter the TFTP server
address in the designated field towards the bottom of the configuration screen.
Once the TFTP server is configured, power cycle the HandyTone ATA.
TFTP checking is only performed during the initial power up. If the configured tftp
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 fails for any reason (e.g.,
TFTP 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 process and
simply boot using the existing code image in the flash.
TFTP may take as long as 1—2 minutes over Internet, or just 20+ seconds if it is
performed on a LAN. It is generally recommended to conduct TFTP upgrade in a
controlled LAN environment if possible. For users who do not have local TFTP
server, Grandstream provides a NAT-friendly TFTP server on the public Internet for
users to download the latest firmware upgrade automatically. Please check the
Service or Support section of Grandstream's Web site to obtain this TFTP server IP
address.
