When the SFP is connected, the switch does not boot after a power failure.
The sfp must be disconnected before the switch boots normally.

Please help

Thank you

- Some suggestions , try another SFP - perhaps it could be partially faulty. Also use latest firmware on the switch (if applicable) and try again (check if the problem then is or becomes persistent) ,

- What happens then ? Do you get an error ? Can you post a screenshot (e.g.) or attach a console , also configure a syslog server on the switch and check for error reporting on it , also when booting.
