I recently purchased a HP MSM410 Access Point. There is no separate power inlet, it uses PoE exclusively. The PoE injector isn't included and has to be purchased separately. Now, I have three D-link AP's that run with D-Link's PoE injectors. Can I use one of them without "frying" the HP device? The PoE injectors says 48V and 0.4 Amp. The HP device says 48V and 0.15 Amps. I guess there is a handshaking process that will eliminate any risk of to many amps being delivered, right? Or is it that the HP device only will request 0.15 Amps of the 0.4 available, is it compatible?
