It's cheaper at Allied:

Yeah, if you're not going to use the Aux port on the 450i, there's no
reason to buy a 60W injector. Just keep in mind that this Phihong
injector is power over the 10/100 data lines. And is - on 1&2, + on 3&6.
It'll work perfectly fine with the 450i APs and 5GHz SMs. And obviously
the Exalt ExtendAir G2. The 450i is awesome with the any pair power setup.
The one thing I will say about this thing is that it runs a bit hot and
if your hearing is decent, you can definitely hear the switcher whining
away.

My Exalt G2 radios came with these really nice POEs that have
diagnostic LEDs and tabs for wall mounting as well as rubber feet for
desktop use. The only downside is they are kind of big, but that's
not necessarily bad, that may help prevent overheating. It has LED
indications for valid 802.3af and 802.3at signatures, as well as a
flashing overload indication.
I looked up the part number, expecting them to be expensive, but
Digi-Key has a bunch of them in stock and the price is quite
reasonable ($38 in single quantity).

From the picture, this is also the POE that I should have gotten from
CyberData to go with the SIP paging amplifier I bought, but instead
they sent a cheaper L-Com POE that has just one dumb LED to show it is
getting AC power. So I paid something like $64 for a $31 POE.
The $100 Cambium POE for 450i is probably more than 36 watts in case
you want to use the AUX port on the AP, but it lacks the nice mounting
tabs and diagnostic LEDs. And 36 watts should be more than enough to
power just the AP.
So I’m inclined to just buy a bunch of the nice Phihong units and use
them on everything. Am I missing something?
