Grandstream Networks HT503 FXS/FXO Manual De Usuario

 

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

To upgrade via TFTP or HTTP, the “Firmware Upgrade and Provisioning upgrade via” field 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 
URL.  

e.g.  firmware.mycompany.com:6688/Grandstream/1.0.0.6  
e.g. 168.75.215.190 

  
NOTES: 
 

1.  The TFTP server in IP address format can be configured via IVR.  Please refer to the 

CONFIGURATION GUIDE section for instructions. If the TFTP server is in FQDN format, it must 
be set via the web configuration interface. 

2. End users recommended using our TFTP server. Its address can be found at 

. Currently, the TFTP server, your HT503 can be 

upgraded from has an IP address 168.75.215.189.  For companies, we recommend to maintain 
their own TFTP/ HTTP server for upgrade and provisioning procedures. 

3.  Once a “Firmware Server Path” is set, the 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 HT503 
will attempt to retrieve the new image files by downloading them into the SRAM. During this 
stage, the HT503 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 
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 HT503 will stop the TFTP/HTTP process 
and simply boot using the existing code image in the flash.  

4.  Firmware upgrades usually take around 2 minutes when 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. Please check the Services section of Grandstream’s Web 
site to obtain our public TFTP server’s IP address.  

5.  Alternatively, user can download a free TFTP or HTTP server and conduct local firmware 

upgrade. A free windows version TFTP server is available for download from 

.  Our latest official release can be 

downloaded from http://www.grandstream.com/y-firmware.htm.  

 
Directions to download a free 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.  

4.  Start the TFTP server, in the phone’s web configuration page 
5.  Configure the Firmware Server Path with the IP address of the PC 
6.  Update the change and reboot the unit  

 
The end-user can also choose to download the free HTTP server from http://httpd.apache.org/ or use 
Microsoft IIS web server.
