Console Not working

[priyapushpe55745]

Hello

I got a Cisco Catalyst 3550 series Switch from a friend and I'm trying to use it for my study purpose.

When I powered up the switch its booting and nothing shows in putty (Just blinking cursor). I have used baud rate of 9600 , 38200 , 57600 , 115,200 and nothing seems to work. 

When I use same cable and putty for my Catalyst 2950 series switch it works fine. 

I used Tera Term as well and same scenario. It works for 2950 and nothing shows in terminal ( Just blinking cursor) 

What could cause the problem ? 

If it is that previous owner configured the con 0 with " no exec " , is there any way to break it?

Or if it is physical damage of console port, can it be repaired ?

Many Thanks

Looks like bad console port may be - if the switch still working as expected, reset to facotry and able to get in GUI.

To reset the switch:

• Press and hold the Mode button. The switch LEDs begin blinking after about 2 seconds. Continue

holding down the Mode button. The LEDs stop blinking after 8 more seconds, and then the switch

reboots.

Try express setup :
