IE2000 with PoE-Switch

[Scapula]

Hello,

we are using IE-2000-16TC-G-N switches in our machines, now we need PoE for RFID Scanners.

So we installed a 8-Port Unmanaged PoE Switch from Murrelektronik (58193)

For my understanding of IEEE802.3af / 802.3at the PoE-Switch should not supply power over the port connected to IE2000

So we connected it to the IE-2000 and fried a port of it.

Do someone know if this is a compatibility problem? did someone experienced a problem like this?

thanks
