I'm looking for a PoE device to power my HP Procurve 420 Access Point. I was recommended by an HP reseller to use the Netgear PoE 101 device as HP do not make one. I have the Netgear adapter but it has damaged the internals of the AP and now it will not power up.

Please could some recommend a PoE device that will work with the HP Procurve 420 AP.  The input for the AP is 3.3V   - 4A (AC adapter).

Cheers

So is the AP dead now?  Does it power up if you plug it in directly?

A couple of things:

Is the Procurve 420 capable of receiving PoE directly or do you need a splitter at the AP?  If the Procurve is does not have a built-in splitter and you plugged a powered Cat5 cable into it, that may certainly damage and ruin the AP.

Cat5 cable does have some loss, so if the cable is too long between the PoE injector and the splitter, you may simply not be receiving enough juice and will have to go with a bigger power supply.

If you are not sure what I am talking about, see the following link for a better understanding of what is involved here:

Let me know.

Now resolved. The 420 does supports power over the CAT5e cable (PoE). It does not work with Netgears 101 PoE devices. It will work with the 2626 PWR switch from HP. On HPs website it states the switch does not issue enough power to the AP. However this is not true, it does provide enough power and does work. It seems HP have made some mistakes in the release notes of their products. If you read through another HP article it does state that it will work!!! Nightmare
