I tried to do a Password Reset Procedure on ws-c3750x-48pf-s v02 - 48-Port PoE, but at the end of the procedure the switch no longer works after multiple restarts and pressing the mode key, I always have in serial console only these three lines

Base ethernet MAC Address: d4:8c:b5:d1:cc:00
Xmodem file system is available.
The password-recovery mechanism is enabled

And nothing after an hour Thanks a lot for your help.

  • Have you used this procedure: cisco.com/c/en/us/support/docs/switches/… ?

  • Also, that switch is EoL, and you need to replace it with something that is supported.

Thank you for your answers, I solved the problem which came from a defective mode button. The switch works fine, except I got this message on startup, it doesn't seem to affect the switch but I don't know how to fix it. Thank you
