Currently have an M-3050 at release 220.127.116.11. After setting the TFTP ip, I'm using the CLI loadimage to upgrade to 18.104.22.168 (sensorsw_3050_611170.jar) . I receive the error 'Image mismatch. Imagefile is for a 4000 system'. It seems I am clearly downloading a file for the M-3050 series. I'm new to this product so any suggestions would be appreciated.
