I am trying to update the SGE2000v1.0 with 24ports to 220.127.116.11:
I got the error "illegal software format" using tftp.
Any ideas, maybe old hardware version v1.0?
the same problem but solved recently - can not use tftp to upgrade from line 1 to line 3 firmware (read release file for details)
before: two SGE2000 with firmware 18.104.22.168
- from product page get 22.214.171.124 or 126.96.36.199 firmware version (Easy Upgrade Utility will be included)
- unpack and use Easy Upgrade Utility to upgrade firmware
- upgrade to 188.8.131.52 by using Web Interface (or tftp)
good luck and let me known if solution works in your case too
