Upgrading a Device Using a TFTP Server and an URL

[Patrick Born]

In the event that you only have a device's firmware bin file, you can still upgrade the device. Here's how:

1. Configure a TFTP server on your computer [there are many free TFTP servers available]
2. Copy the binary file, for example spa901-5-1-5.bin to the appropriate directory on the TFTP server
3. Determine the IP address of the phone [SPA901, dial **** and then 110# for the IP address] [example: 192.168.2.10
4. Determine the IP address of the TFTP server: [example: 192.168.2.150]
   Windows: ipconfig /all
   UNIX: ifconfig -a
5. Verify that you can access the device's web-ui by navigating to http://<IP_address_of_phone>/
6. Cause the phone to pull the firmware from your TFTP server:
   http://<IP_address_of_phone>/upgrade?tftp://<IP_address_of_TFTP_server>/<binary_firmware_file>
   Example: http://192.168.2.10/upgrade?tftp://192.168.2.150/spa901-5-1-5.bin
7. Watch your TFTP server's log file to verify that the device successfully downloads the firmware
8. Use the device's web-ui to view the firmware version and verify that it is running the updated version.
