Upgrade Firmware by TFTP Method

You can download the latest firmware file from Yeastar Firmware Download center to your TFTP server. Then upgrade the PBX firmware from the TFTP server.

  • If the TFTP server is your local PC, this upgrade method is suitable when the PBX cannot access the Internet.
  • If you fail to upgrade firmware via TFTP server, we suggest you to close safety configuration like firewall or virus defense.
  1. Create a TFTP server, take TFTP32 for example.
  2. Configure a TFTP server. Click Browse to select the firmware file uploaded path.
  3. Go to Yeastar system upgrade page, clickMaintenance > Upgrade > Manual Upgrade.
  4. If you want to reset the configuration to factory defaults, check the option Reset Configuration to Factory Default.
    Important: If you check this option, all your PBX configurations will be erased. We don't suggest you reset the PBX before upgrade firmware.
  5. Set Type to Download From TFTP Server.
  6. In the TFTP Server field, enter the IP address of the TFTP server.
  7. In theFile Name field, enter the firmware file name.
    Note: The file should be a .bin file. For example,
  8. Click Download.
    The PBX will start downloading file from the TFTP server, and upgrading the firmware automatically.
    Note: When the PBX is updating the firmware, do NOT turn off the power. Or the system will get damaged.
