Smaller than it looks, works perfectly
on August 17, 2011
This is a POE (Power Over Ethernet) Injector. It adds 48 volt DC to an ethernet cable to power devices that support POE (usually VOIP Phones and some outdoor Wifi Access Points). It includes the white box pictured on amazon.com, a separate power supply, and possibly an ethernet cable (I can't remember).
For some reason, the picture made me think that it would be larger. The actual product is quite small.
I've used this for about a month and it works great.
