Active PoE means the right power at the right time. An active PoE injector negotiates with the powered device to deliver the voltage needed, so there are no concerns about accidentally burning out lower powered or non-PoE devices. Power is only added to the data cable when an 802.3af or 802.3at device is connected.

If I use only two ports does that allow for 60W on each one?
Since the AT-4 is only rated for up to 802.3at PoE, the maximum wattage you can output per port is 30 watts even if you only use 2 ports. If you are wanting 60 watts per port, my best recommendation would be our BT-1-55V60W which outputs 802.3bt rated PoE. Since this only has one uplink port and one PoE port, you would need one BT-1-55v60w for every device you want to power via PoE.
the current PoE injectors I have you need to disconnect the device end after a power outage to get them to work gain. Does your PoE device power up no problems after power outages?
Yes the AT-4-56v120w should power back on once power is restored after an outage, given that no damage was caused to the power supply, or injector itself.
Does this use hardware 2-event PoE classification or LLDP?
Our active injectors do not use the LLDP, or layer 2 negotiation protocol. This injector uses an auto-negotiation that is compliant by the 802.3at standard. For more inforamtion, please contact our techinical support team: 512-479-0317
