Using a D-link PoE injector with HP Procurve AP?
Hi,
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?
Thanks

How much the injector will actually add to your power bill depends on what type of supply it is. If it has a heavy transformer-type supply, then it will likely draw about 19 or 20W all the time it's plugged in; if it's the lighter switching-type power supply, without a transformer, then it should use only about 7.3W (or less, if the PoE device is drawing less than its label rating).

Thank you. I'm not sure if it's a switching supply or not. When it comes to power, a small footprint is always preferable. It's probably negligible to our Dell blade server rack in the server room though... =)

Thank you, I'll do a test tomorrow.
