Just wondering I upgraded and old lab WS-3524-XL Swith to the current IOS, now I am getting errors.
I need to go back to the previous version, that I do not have any longer
The current version is c2900xl-c3h2s-mz.120-5.WC13
and this is the old version I am looking for c3500XL-c3h2-mz-112.8.2-SA6
The error message is POST FAILED: FastEthernet0/1 failed front-end loopback test
