We are looking for an 8 port switch that can be powered over ethernet. Looks like a device like this is a powered device (PD). I've heard that cisco makes switch products like this but don't know how to locate them.
I did come across this 5 port startec switch... but more ports would be ideal. This switch does not need to power any additional PoE devices besides itself. https://www.amazon.com/Port-Gigabit-Ethernet-Switch-PoE-Powered/dp/B01273JAD0
This is the current candidate PSE switch: Cisco (SG300-52P-K9-NA) 52-Port Gigabit PoE Managed Switch https://www.amazon.com/gp/product/B00BHZJMB0/
I would prefer cisco or linksys because I'm familiar with those brands but reliability and value are the key items. Cisco can sometimes be expensive.
