I got a network switch that is showing zero activity across about a dozen ports, the most important of which is the feed from the router from upstairs. This happened out of nowhere and I don’t think it’s the switch unless the backup I tried is also bad. I also tested the cable leading from the router and it passes the continuity test at the very least. Even if that line was dead, wouldn’t the switch show at least SOME activity as devices try to access each other? I’m no IT master, but peer to peer still happens in a network, doesn’t it? Anyway, it’s been a few days of trying to fix this myself, so I finally turn to reddit. Any ideas, lads?
These probably won’t help but saying them outloud anyways. Maybe the next person has an issue that these will help.
Is there a reset button? Looks like an unmanaged switch, so probably not. Sometimes devices have a recovery mode.
What type of power cord? if it has a transformer, maybe you got the wrong one. It happens. If underpowered, a device can light up but not operate.
