M4300 24x24f unresponsive- amber power light
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 ...
Hi TechAtAnimal,
It looks like the switch cannot boot up successfully, due to Power1 or power2 is solid amber.
Please check you connect console port accurately, not physical ports, you can find the ports on the left of the front panel, which display ‘console 115200…’ . After connecting the console port, even the switch cannot boot up, when you pull out the power attaching plug, not PSU, after you plug into attaching plug, you can see Boot Logging.
Look forward your reply.

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.
Hi TechAtAnimal,
Agree with TCan’s suggestion, it sounds like your console configuration is wrong. I only add two pictures to introduce that how to change it.
Due to I cannot see your pictures clearly, so e.g. if use the ipop.exe to check logging, PC port is COM7, please change configuration as below:
Not pay attention to ip addr.
PC change port settings:

Thank you Tcan and Elaine, I didn't realize Tera Term was resetting itself to a different baud rate every time.
I've gotten actual text now, so I've included a better quality picture of what the error screen I am getting says.
Looks like your firmware is corrupt.
I would wait for a Netgear rep to get back to you as to how to recover it, all my experience is with Cisco kit (I can tell you how to do a recovery on a Cisco switch if that will help!)
I have had a search online and found this docuemnt for recovering the software on a Netgear router but I have no idea if it is the same for a switch (it's very similar to a Cisco recovery). https://kb.netgear.com/22688/How-to-upload-firmware-to-a-NETGEAR-router-using-TFTP
As I said, I would wait for the official answer.
