PoE or Power over Ethernet typically runs at 48 volts. Certain Peplink devices such as the Peplink Pepwave Max HD2 have the ability to power PoE devices using this optional power adapter. This kit enables use of up to four 802.3af PoE output ports to run wireless access points, splitters, IP cameras, desk phones and other low-power network equipment. It contains a 48V power supply that gives the router the extra power it needs to run other devices. As of Hardware Gen 6 (HD2) you do not require a license key to activate the PoE ports.
Compatible with MAX BR1 ENT, MAX HD2 (hardware revision 6 only), HD2 with MediaFast, HD4, 700, and MediaFast 200
