I have a meraki switch and it is blinking orange and green really fast on the front of the switch. This is a 24 port switch and 18 of the ports are being used. The computers or phones that are plugged into these ports are working fine. When I try and plug in another device to the the open ports it will not light and the device does not connect. Any ideas? I went to the meraki web interface but I don't see anything that I can tell is off.
