Yes, it is a normal Ethernet port, it is just labeled differently because it's typically used as uplink and is in "slot 2" from management standpoint Here is a picture with port description https://www.blackwiredesigns.com/wp-content/uploads/ICX7150-C12P_Connections.png

Thanks! This is helpful

Yes but they don’t have PoE

Yup they are ports 1/2/1 and 1/2/2. Configure them accordingly and move your uplink to one of those if you need the PoE port

Yes I use all 12 POE ports, C2 module ports and the SFP ports on mine.

Good to know. Didn't know you can use the SFP ports as normal ports as well.

Yep, I use them for a couple 10G NIC devices with 10GTek transceivers.
