I purchased a used GSM7352Sv2 (V2H1) that worked fine when I first powered it up. One of the first things I tried to do was upgrade to the latest firmware (10.0.0.52), carefully following the procedure in the release notes. The upgrade appeared to work, but when it tried to reboot to the new image, it wouldn't come up. Now, upon applying power, the fans come on, the power LED is amber, the fan, M1, and M2 LEDs are green, the LEDs for channels 49 and 50 (the SFP+ channels) are amber, and the ID shows 1. It never progresses past this point. Nothing ever happens on the console port (there are no LEDs lit on my serial-to-USB cable, indicating the console port is never turned on), and pressing the reset button on the front panel does nothing (I've tried pressing it, pressing it and holding it for 10+ seconds, and holding it down as power is applied). HELP!!!
Thank you for responding. Yes, I've read each of those articles, but none of them applies. As I stated, my unit never gets to the point of communicating over the console port. It appears the boot loader is not even starting, or crashes before it initializes the console port hardware. I was hoping the LED configuration would mean something to somebody, as it comes up this way when power is applied and never changes.

Have you tried using a serial cable instead of serial-to-USB cable as well as using another PC/laptop that has a serial port in order to isolate the problem? If ever you have already tried it and still same problem, then it seems that the GSM7352Sv2 switch needs to be replaced.
