I configured the switch, it could reach my router and the network but I wanted PoE to work (as advertised and as paid for), so I contacted the seller, we agreed on replacing the board after I opened up the switch and saw the blown transistor and burnt IC.

Prior to installing the 'new' board the switch would boot per usual (without pressing 'b') but throw a loop of PoE errors (every 1 to 10 seconds) and I could press 'b' and enter the boot prompt (at startup only of course). But now I can't flash anything without a functioning switch or console - the console is not doing anything now, just displaying 'press 'b' for boot' no matter if I press 'b' or not.Ĭlick to expand.Yes, in the attached image it shows 'Interrupted by pressing b'. My thinking is the 'new' PoE board needs to be flashed to the latest PoE firmware version as was the 'old' damaged board that I had updated the PoE firmware on. I have had it powered on for 2 hours and the console never updates past press 'i' or 'b'. If I don't press 'i' or 'b' then the switch still does nothing (except keep the fans on full blast). So I replaced the PoE board and when I power on the switch and hook a laptop to the console port with Putty I get the familiar console prompt and I can press 'i' or 'b' but then nothing happens, the switch does absolutely nothing new: displays the press 'i' and press 'b' prompts and nothing else but fans. I configured the switch and was using it with a couple of dev laptops and all was fine except no PoE. Surprisingly, the switch was functional and I was able to run commands even with the blown board - but the console was flooded with the PoE errors I posted above and of course the PoE did not supply any Power over Ethernet due to the blown board. However, there was a blown transistor on the original PoE board and an IC with a burn hole in it (not me, bought used). Yes, I did update the switch, including the PoE firmware using docs.
