Hi! We have an m4300x24f managed switch. It is an RMA replacement so was hooked in three weeks ago. When we plugged it into the power it worked great three weeks ago, was able to log in just to make ...
Well, I managed to get a response in the boot logging window however it shows a random pattern of "B"'s for about a minute and then goes onto infinite "0"'s. I've included pictures of how it looks.
Random characters are usually because you have connected at the wrong speed.
The default is 115200 but it is possible that somebody has changed it. Supported speeds are 1200 | 2400 | 4800 | 9600 | 19200 | 38400 | 57600 | 115200
Try each one until you find the right one. For each speed, change your software then re-power the switch.
Other settings are 8 data bits, no parity, 1 stop bit. Personally I use no flow control. These should be the settings whatever speed you connect at.
