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 no noticeable scratches or stains, and it appears to be in good condition. During the listing process, I confirmed its operation by connecting it to a PoE-compatible router, and I was able to confirm that communication and power connection were working without any problems. Mounting hardware is not included, and only the items in the photos are included. I have about three 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 contact 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. With 2.5GbE/1GbE support, you can upgrade to a PoE-compatible network easily without changing the configuration or settings of your network devices, regardless of your network environment. 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.
