Grandstream Networks HT386 user manual Software Upgrade, IVR Method

SOFTWARE UPGRADE

Software upgrades are performed via TFTP or HTTP. The corresponding configuration settings are in the ADVANCED SETTINGS configuration page.

FIRMWARE UPGRADE THROUGH TFTP/HTTP

Our latest official release can be downloaded from: http://www.grandstream.com/y-firmware.htm. To upgrade your unit firmware, follow these steps:

1.Under Advanced Settings webpage, enter your TFTP or HTTP Server IP address (or FQDN) next to the “Firmware Upgrade: Upgrade Server” field.

2.Select via TFTP or HTTP accordingly.

3.If you plan to use Automatic Upgrade, set it to “Yes”, otherwise No (this will make it check for upgrade every time you reboot).

IVR METHOD

Firmware server in IP address format can be configured via IVR. If firmware server is in FQDN format, it must be set via web configuration interface.

UPGRADE THROUGH TFTP

To upgrade firmware via TFTP, set the field “Firmware Upgrade and Provisioning: Upgrade Via” to TFTP. The TFTP server can be configured in either IP address format or FQDN. To configure the TFTP server via the Web configuration interface, follow these five steps:

1.Open your browser to input the IP address of the HT–386.

2.Enter the admin password to enter the configuration screen.

3.Enter the TFTP server address or URL in the “Firmware Server Path” field near the bottom of the configuration screen.

4.Once the “Firmware Server Path” is set, update the change by clicking the “Update” button.

5.Reboot or power cycle the unit.

If the configured updating server is found and a new code image is available, the HT–386 will retrieve the new image files by downloading them into the HT–502 ’s SRAM. During this stage, the HT–386 ’s LED will blink until the checking/downloading process is completed. Upon verification of checksum, the new code image will 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 HT–386 will stop the TFTP process and simply boot using the existing code image in the flash.

A firmware upgrade may take as long as 20 minutes over the Internet, or 20+ seconds if performed on a LAN. Grandstream recommends conducting firmware upgrades in a controlled LAN environment if possible.

NO LOCAL TFTP SERVER

For users who do not have a 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 Services section of Grandstream’s Web site to obtain this TFTP server IP address. Alternatively, user can download and install a free TFTP or HTTP server in his LAN for a firmware upgrade. A free Windows version TFTP server can be downloaded from: http://support.solarwinds.net/updates/New-customerFree.cfm.
