I am trying to upgrade the firmware on a Cisco SG200-50 switch via HTTP/HTTPS
When I try and update the firmware to the latest version (18.104.22.168)
I am getting an "illegal format" error when I use HTTPS. The filename is sx200_fw-14115.ros and it was downloaded from the Cisco website at:
The switch firmware is at : 22.214.171.124
Can you let me know how to get the firmware to the latest version?
Not sure what went wrong " "illegal format" " as per this error concern, the firmware not recognising.
i have seen people upgrading this forum as same issue, but upgrading to stepwise made them sucess.
