Hi all,
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

Did u replace the 2900Xl ios with the 3500XL version?
If so not sure if it would be compatible. Just but the old ios back on the 3500XL
bye flash...

Friend,
The error you are seeing during post does not suugest that it is because of the IOS.
Post failures afre more likely a cause of hardware failure
