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). 

 

To upgrade firmware via HTTP, the field “Firmware Upgrade and Provisioning: Upgrade Via” needs to be 
set to HTTP.  The “Firmware Server Path” should be set to where the firmware files are located.  
 
For example, the user can use the following URL in the Firmware Server Path:

firmware.mycompany.com: 

6688/Grandstream/1.0.0.29  

where firmware.mycompany.com is the FQDN of the HTTP server. It can 

also be in IP address format. “:6688” is the TCP port the HTTP server listening to, default http server 
listens to port 80.  “/Grandstream/1.0.0.29” is the RELATIVE directory to the root dir on HTTP web server.  
 

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 GXW–400x.  
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 GXW–400x will retrieve 
the new image files by downloading them into the GXW–400x’s SRAM.  During this stage, the GXW–
400x’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 GXW–400x 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.  
 

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:
