  • Will the WT-AT-4 work with Proxim 81xx series radios and deliver Gigabit Ethernet speeds?

    Yes, the WT-AT-4 delivers Gigabit data speeds and is 802.3af/at compliant. It will work with the Proxim ORiNOCO AP-8100; with a max power draw of 12watts, I would recommend using a 48 volt, 60 watt power supply.

  • Does the WT-AT-4 have the 4-Position Phoenix contact for power input like the WT-AT-8?

    The WT-AT-4 does not have the Phoenix contact option available. Typically, 120 watts should be enough to support all 4 ports.  Please feel free to contact our customer support, we would be happy to find a solution for your specific set up.

  • Can I use this with a 24 volt power supply?

    No, this active injector only takes voltage inputs of 44-56volts. If you are looking for a passive injector supplying 24 volts POE similar to this, I recommend our WT-GPOE-4-B-24v60w

  • Whats the difference between active and passive?

    Active means this Power Supplying Equipment (PSE) sends a very short signal to your Power Device (PD) as soon as it is connected to determine how much power it needs, then this PSE sends only that power. The most common case for this is when you have a PoE port someone could plug a laptop into by accident. The laptop isn't PoE and could be damaged by it, so, if you have an active PSE like this one, it won't send any power to the laptop accidentally connected to it. Passive sends PoE power all the time, which works great for most PoE specific applications like cameras, wifi access points, or a port you know only PoE devices are attached to. Both work great for the right application. 

  • What is the difference between WT-AT-4 and simply AT-4? The image of the device indicates WT-AT-4 whereas the description states only AT-4. Searching the internet I see devices with same specs sometimes labelled as WT-AT-4 or AT-4. If ordered will I receive a device labelled WT-AT-4 or AT-4?

    They are both the same device. Last year we changed our products and skus. This device was changed from WT-AT-4 to just AT-4.
