I have an old WS-C4503 (without the E) but it has an old ios version 12.2(25)EWA4, and since 2015 there is no support anymore.
Does anyone knows what was the latest version?
here is the list of latest version for your kit ;
From dir command: 27262976 bytes total (14767620 bytes free)
You're stuck. This means the flash only as 32 mb. Just enough for 12.2(25)EWA train. You can't even upgrade to 12.2(31)SG because it requires 64 mb flash.
Does the supervisor card have an empty CF in the front?
