GG3428MP Fans go crazy.
We installed a SG3428MP switch about a little over a month ago. for 3 weeks it worked flawless. Then it dropped all the AP that were using PoE from the switch, limited Internet connectivity. Rebooting the switch worked for only a few hours. When I arrive at the site, the fans were screaming but blowing cold air. Rebooting did restore the fans to normal operation but would not restore the PoE to the 3 AP's connected to that switch. I had to remove power and restart to get it back to normal. I thought after that all would be good. Not the case. The problem has become worse with now needing rebooting or full power down to get it to work. Sometime as often as 15 minutes. When this happens the cpu usage drops fro a reported 12 to 30% to around 5% and the fans take off. Anything needing PoE is disconnected for no reason I can tell. Anyone got any ideas?
Model:TL-SG3428MP v1.0
Firmware Version:1.1.7 Build 20221130 Rel.42340
2 EAP650
1 EAP610
OC200
ER7206.
Any help would be appreciated.
