Cisco Aironet Power Injector (AIR-PWRINJ3)

I knew I needed one of these just for the bench while I configured the cisco 4200 series AP, and I would be needing to do the same for more APs later. The price was right. When I got it, though, it didn't work. I immediately contacted the seller through Amazon and was given a return authorization within a few hours of my request. The seller got it back and reported that it was OK on his bench. He asked what AP I was trying to power and said it wasn't designed for that series. He offered one that was designed for it or to give my money back. I elected the proper replacement, and it was in my mailbox shortly. The seller said the price difference was insubstantial, and he accepted an even exchange even though I had offered to pay any upward difference. I'm still not sure what the technical differences are, but the description should include that info.

The Aironet access points suck power (35watts or so with both radios running). Most POE switches don't deliver that kind of power. These things do. But they don't come with power supplies. Somewhere in the fine print it says to use the power supply that shipped with your Aironet device, but because the Aironets are designed to work with POE they don't come with power supplies; you have to order that as an extra.This thing is almost more trouble than it's worth, because you have to find the right power supply and order it, too. I think I should have just bought a 6-port PowerDsine high-power midspan, which is priced about the same as 3 Cisco power injectors + 3 Cisco power supplies.

Great way to provide power to WAPs that are going to be way too far for power and are not connected to a PoE switch. In addition, having injected (or PoE) power keeps the cabling easier and clean while making it easier to cold boot the access point.NOTE: for those who are not aware the Cisco AIR-PWRINJ3 is the economical way to add PoE to those Wireless Access Points (WAPs) that already have the power supply. So the proper Cisco power supply (or equivalent) is required and is not included with the unit.

I don't mind purchasing the power supply separately but this wasn't available at any electronic retail outlets in Houston. So, i had to wait an extra week for the power supply.

It works great with my new Cisco 1320 AP. Relatively low price tag and allows for the possibility to use the AP without a power supply near by. This unit doesn't come with the power supply, so you'll have to use the one that came with the AP or purchase a new one.

it was offered together with the AIR-AP1141N-A-K9 and says that would power up these models.but the fact is that it does nothing at all.later somewhere in the site it say it only works with the following compatibility: Cisco Aironet Series Access Points: 1100 , 1200 , 1220 , 1230so please clear this doubt and i would rate again.

I bought these to power some EnGenius access points I had bought. These werent compatible at all. So I ended up having to ship them back. They are also rather bulky.

I installed this exactly per the instructions included with the product. However, the "Device Status" LED is off, and the device doesn't receive power. I'll be returning for a refund.

Did what it said on the tin, good price! good delivery

Have to agree with this:I cannot comment on the quality of this item as it does not come with a power supply. The advert is misleading and is not clear that you need to buy an additional PSU. So unfortunately I will be sending it backWhat's the point with no power supply!

El producto me vino incompleto. Lo usamos en el trabajo y va bien, pero el reacondicionado me vino sin cables.

!! Achtung wichtig. Der POE Injector arbeitet mit dem pre-standard Verfahren und nicht mit IEEE 802.3af.Dadurch ist die Benutzung mit POE-Geräten nach IEEE 802.3af nicht möglich. Z.b. der Cisco WAP200 WLan-Router läuft damit nicht.Desweiteren ist kein Netzteil im Lieferumfang enthalten und man benötigt zum Betrieb ein 48Volt Netzteil.
