Software upgrade can be done via either TFTP or HTTP/HTTPS. The corresponding configuration 
settings are in the ADVANCED SETTINGS configuration page. 
  

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.  
              firmware.mycompany.com:6688/Grandstream/1.0.1.8 
or 

 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/ 
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 GXW400x will 
attempt to retrieve the new image files by downloading them into the GXW400x ’s SRAM. During 
this stage, the GXW400x’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 GXW400x 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

.  

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

Download a free TFTP server (windows version) from 

http://tftpd32.jounin.net

 or 

http://support.solarwinds.net/updates/New-customerFree.cfm

. Download a free HTTP server from 

http://httpd.apache.org

 or use Microsoft IIS web server.  

 

 
Instructions to Upgrade using Local (TFTP) Server  
 

1.  Unzip the file and put all of them under the root directory of the TFTP server.  
2.  Put the PC running the TFTP server and the GXW400x device in the same LAN segment. 
3.  Please go to File -> Configure -> Security to change the TFTP server's default setting from 

"Receive Only" to "Transmit Only" for the firmware upgrade.
