Planet’s POE-400 is a Power Over Ethernet 4-Port Injector hub. Equipped with 4 10/100Base-TX Fast Ethernet ports, the POE-400 supports 48V DC power for any remote 802.3af powered device (PD) like wireless LAN access points, IP phones, and IP cameras. The supporting power supply of 70 Watts, provides sufficient power to the 4 remote devices.
There are 8 RJ-45 STP ports on the POE-400. Half of the ports function as Data and the other half function as Data and Power. Each of the Data and Power ports are an injector, which inserts DC voltage into the CAT 5 cable to allow the cable between the Injector and Splitter to transfer data and power simultaneously.
