This is a Buffalo BIJ-POE-1P2G 2.5G-compatible 1CH type PoE injector for businesses. It is a used item from a corporate entity. There are some scratches and wear and tear from use. Before listing, I tested its operation and confirmed that it can communicate and connect to power without any problems when connected to a PoE-compatible router. Mounting hardware is not included, and only the items in the photos are included. I have about four of these, although the appearance may vary slightly. If you wish to purchase multiple units, I am willing to consider a small discount, so please feel free to consult with me in the comments.

[Product Description] [Add PoE power supply equipment and make existing network devices PoE compatible] Simply add an injector where you want to introduce PoE functionality, leaving your existing network devices as they are.

By using it with a wireless LAN access point or IP phone that supports PoE power receiving function, you can install the equipment without worrying about the location of the power outlet. *It only provides PoE power and does not have a switching function. A separate switching hub is required.
