Hi There! I would recommend for you to install the Cisco Recommended IOS, since yours is quite a bit old. Install it via xmodem, if you change the baud rate to 115200 it wont take that long. If the issue persists it could be a possible hardware issue.   Details Description : UNIVERSAL Release : 15.2.4E8 Release Date : 18-Mar-2019 FileName : c2960x-universalk9-mz.152-4.E8.bin Min Memory : DRAM 128 Flash 64 Size : 23.23 MB   ( 24359936 bytes) MD5 Checksum : 2284cbaf62484a2689880b6a4eff7629   SHA512 Checksum : de31af3b988c23be4c1eaa3977c87a16   ... regards,   Ben ...
