Software Configuration

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

FIRMWARE UPGRADE THROUGH TFTP/HTTP

To upgrade via TFTP or HTTP, the “Firmware Upgrade and Provisioning upgrade via” field (IVR option 17) needs to be set to TFTP or HTTP, respectively. “Firmware Server Path” needs to be set to a valid URL of a TFTP or HTTP server, server name can be in either FQDN or IP address format. Here are examples of some valid URLs:

firmware.mycompany.com: 6688/Grandstream/1.0.0.18

168.75.215.190

There are two ways to set up the Upgrade Server to upgrade firmware: IVR and Web Configuration Interface.

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.

Once a “Firmware Server Path” and the upgrade protocol are set, please update the settings and reboot the device. The HT–496 retrieves the new image files by downloading them into the HT–496’s SRAM While downloading, the HT–496’s LEDs will blink until the checking/downloading process is completed. Upon verification of checksum, the new code image is saved into the Flash. If the TFTP/HTTP fails for any reason (e.g., TFTP/HTTP server is not responding, there are no code image files available for upgrade, or checksum test fails, etc), the HT–496 will stop the TFTP/HTTP process and re-boot using the existing code image in the flash.

The firmware upgrade may take as long as 20 minutes over Internet, or 20+ seconds if using a LAN. Grandstream recommends a controlled LAN environment for firmware upgrades if possible. For users who do not have a local firmware upgrade server, Grandstream provides a NAT-friendly TFTP server on the public Internet for firmware upgrade. Check www.grandstream.com for our public TFTP server’s IP address.

NO LOCAL TFTP SERVER

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 Support/Download section of our website to obtain this TFTP server IP address: http://www.grandstream.com/y-firmware.htm. Each product has a unique TFTP server address.

Alternatively, download and install a free TFTP or HTTP server to the LAN to perform firmware upgrades. A free Windows version TFTP server is available: http://support.solarwinds.net/updates/New- customerFree.cfm.
