Hello Usman,

The fan might get stuck with dust - the 2950 are out there for a couple of years.

Regarding the unrecognised characters, I suggest doing the same what has been suggested for similar problems in this forum: try setting the speed of your COM port to each value in the range from 1200bps up to 115200bps and see whether you can gain access to the console. Also make sure that your console cable is OK.

By the way, what is the status of the LEDs on the front panel? Does the switch appear to be booting? After a few minutes, do at least these LEDs revert to the normal state?

Best regards,
