Re: Fortigate 81E PoE Ports failing
Not familiar with those fgt poe devices, but someone correct if I am wrong on this, but at least on some POE switches, there is a max. voltage load overall, that is shared between the POE ports - so connecting just one device to one of the ports, you should get a "full load", then connect another device to another port and the load on the first port dips slight, connect another cable to another port and same power "dip" on the first two ports, etc. Something along those lines.
