Hi, I restarted Catalyst 2960L-8PS switch today, but the switch never came back up. I consoled in and found that the switch was constantly restarting. The error messages are:
1.) Verifying MCU firmware... Fail
2.) MCU firmware Upgrade Fail - failed to get MCU data
3.) Invalid parameter block. Using Mac address of 0:0:0:0:0:0
4.) POST: ACT2 Authentication: End, Status Failed driver class subsystem initialization failed.
5.) Cloud not get Msemi to gracefully enter recovery state.
6.) nand bad command - shows bad blocks
Here are the screenshots
Is there a way to recover the switch?
