Firmware 1.0.1.8 Last Updated: 5/2008

SOFTWARE UPGRADE

Software upgrade can be done via either TFTP or HTTP/HTTPS. The corresponding configuration

settings are in the ADVANCED SETTINGS configuration page.

FIRMWARE UPGRADE THROUGH TFTP/HTTP/HTTPS

To upgrade via TFTP or HTTP/HTTPS, the “Firmware Upgrade and Provisioning upgrade via” field needs

to be set to TFTP, HTTP or HTTPS, respectively. “Firmware Server Path” needs to be set to a valid URL

of a TFTP or HTTP/HTTPS server, server name can be in either FQDN or IP address format.

Here are examples of some valid URL.

e.g. firmware.mycompany.com:6688/Grandstream/1.0.1.8

e.g. 168.75.215.189

NOTES:

• TFTP server in IP address format can be configured via IVR. Please refer to section

CONFIGURATION GUIDE for instructions. If TFTP server is in FQDN format, it must be set via

web configuration interface.

• Grandstream recommends end-user use the Grandstream TFTP server. Its address can be found

at http://www.grandstream.com/firmware.html

. Currently the TFTP firmware server IP address is:

168.75.215.189. For large companies, we recommend to maintain their own TFTP or

HTTP/HTTPS server for upgrade and provisioning procedures.

• Once a “Firmware Server Path” is set, user needs to update the settings and reboot the device. If

the configured firmware server is found and a new code image is available, the GXW4024 will

attempt to retrieve the new image files by downloading them into the GXW4024’s RAM. During

this stage, the GXW4024’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/HTTP/HTTPS fails for any reason (e.g. TFTP/HTTP/HTTPS server is not responding, there

are no code image files available for upgrade, or checksum test fails, etc), the GXW4024 will stop

the TFTP/HTTP/HTTPS process and simply boot using the existing code image in the flash.

• Firmware upgrade may take as long as 15 to 30 minutes over Internet, or just 5 minutes if it is

performed on a LAN. It is recommended to conduct firmware upgrade in a controlled LAN

environment 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.

• Grandstream’s latest firmware is available http://www.grandstream.com/firmware.html

Oversea users are strongly recommended to download the binary files and upgrade firmware

locally in a controlled LAN environment.

• Alternatively, user can download a free TFTP or HTTP server to upgrade local firmware.
