7.4. Remotely Updating Firmware Using the Bootloader
The PoE-VOICE-EB firmware can be remotely updated over the network. The bootloader uses the Trivial File
Transfer Protocol (TFTP) to transfer an image file from the PC (TFTP Client) to the PoE-VoIP-EB (TFTP Server).
The transfer must be binary and the file name in the PoE-VOICE-EB’s file system must be “boot.img”.
