Welcome to the PoE Texas Manual for the AT-1-55v30w that uses a wide range of DC input, in particular from solar power systems, and converts it into IEEE 802.3at Power Over Ethernet!


The purpose of the manual is to help you quickly and effectively navigate the installation and functions of your new Power Over Ethernet Midspan. 


Our goal is to make our products as intuitive and simple to use as possible, so we value your feedback and questions directly to us at service@poetexas.com.  Phone +1-512-479-0317.

What’s Inside



  • 1 X Midspan Injector


Additional items you’ll need not included:

1 – DIN rail

2 – Patch cables to the switch and home run cables to the device

3 – DC cable to solar charge controller

General Installation

A midspan like the AT-1-55v30w is a simple device to add on to a network port, and the purpose is to add PoE using a wide range of input power to any network.


With this DIN rail mounted device, simply mount it on a DIN rale near the networking switch you’d like to pair it with.  Then, using a short Ethernet patch cable from the switch’s data port to the LAN port on the PoE midspan.   Then the POE port adjacent to the LAN port will now have that IEEE 802.3at (30 watts) power budget and up to gigabit pass through data.  Finally, connect the DC power supply to the Phoenix style connector on the top.


The AT-1-55v30w is also surge protected, so, while it cannot be mounted outdoors by itself, you can connect it to outdoor devices with confidence.  In order to make the surge protection fully functional, you will need to properly ground the connector on the side of the device.


Not sure what grounding is?  Panduit has some great graphics around grounding.


There is no configuration necessary with this device.  Simply plug it in.

The green LED indicates power on.  If the green light begins to blink at any time, it could indicate there is a short in the circuit or a compatibility issue.



1 – At the injector, disconnect the PoE port from your device.  Use a PoE Tester to confirm the device is able to power on using a short jumper cable.

2 – At the other end of the network cable to your device, disconnect the device and use the PoE Tester to confirm it is able to negotiate PoE.

3 – Connect the PoE Tester to the end device to monitor power consumption.


If you’re able to power on the device with the PoE Tester inline, it’s likely a compatibility issue.  Please contact us at service@poetexas.com to find you the right solution.
