I used tftp solution and every thing is normal with other versions like R308 version, and I already upgraded that DSLAM to MA5616V800R312C00 version, but in R306 version I got this message:

 ---------------------

File(s) saved to flash successfully: Version match file, Host program, EPON
Firmware, BIOS file, VOIP Service file, FPGA file, CPLD file
  Failed to load part of files in the packet file, please restart the active
board and load again

Is there any idea what is happeing here?

Thanks in advance.
