Hi Guys,
Last week I tried to upgrade our edge 3750X switch (two switches in a stack), from c3750e-universalk9-mz.152-2.E.bin to c3750e-universalk9-mz.152-4.E5.bin.
Previously I copied the new IOS to both flash: and flash2: from TFTP, ran command 'boot system switch all flash:c3750e-universalk9-mz.152-4.E5.bin, and then 'wr mem'.
Later I consoled into the master switch and reloaded. The master switch booted into the new image successfully, but the member switch got stuck in a booting loop. The new IOS was loading, and went nearly to the end, and the master switch could see the member at some point. Then the process started all over again, and it was endless!
I tried powering the member switch off, and then on again - still the same. Tried removing stacking cables, and restarting - still no joy. Then booted the member into SWITCH: prompt, and then into the previous IOS - still a loop! I didn't know what else I could try, so at the end I powered the offending switch off and left it as it was (as the master switch was providing all the services).
Please could you advise how to resolve this issue? Any advice would be appreciated.
Regards,
Lucia
