MES3000 Ethernet switch series 51
1. The switch downloads the text file and reads the firmware file name on TFTP server.
2. The switch downloads the first block (512 bytes) of the firmware image file from TFTP server
with the firmware version.
3. The switch compares firmware image file version, downloaded from TFTP server, with the
active image of the switch firmware. If they differ, the switch will download the firmware
image from TFTP server and make it active.
4. When the firmware image download is finished, the switch will restart.

conditions are met:

name (DHCP Option 67) in ASCII format.

(running) configuration will be copied into the initial configuration (startup).
