connecting to an X440 switch via the serial connection is not working

[Penny]

I'm trying to connect to an Extreme x440 Summit switch via the serial port using Putty. When I connect, a bunch of garbage appears on the screen and just keeps scrolling. I can connect to another Extreme x440 without issue using the same setup. Does anyone have any suggestions? I can't factory reset because I can't serial into the switch

Same issue with an Extreme Networks X250e-24p that I just purchased on Amazon. Cable\setup works fine with other units. Has anyone resolved this or should I just return the switch?

This is what the X450e answers in the putty, someone knows what is happening, I want to reset it to factory, no port is active
