View Full Version : WAR boards compatible with 802.3af PoE
Is the PoE of the WAR board compatible with 802.3af (specifically to get power from a Cisco 3560) ?

No, they accept from 9V to 28V on the unused cat5 pairs, called passive POE. These require an adapter and POE injector. We supply the injector.
So I suppose a splitter like (MIT 06DT PoE Active Splitter, 802.3af Compliant) could be used. Do you recommend any ?

I don't have access to that type of equipment. We use a standard wall adapter with from 15V to 24V output.

Pac Wireless makes a 12V/1A "picker" that is 802.3af compliant

Netgear makes a little 8 port switch with 4 802.3af POE ports

I was thinking of trying this combination on my next tower..
We use another radio that is 802.3af compliant for backhauls..
Anyone tried this? We've used the switch for some POE phones, at
a companies site, but never for a tower situation. It worked great
for with the 802.3af phones.

From the picture, it doesn't look like the WAR boards have a barrel power connector. Is it POE only?
( used to wrap/soekris with both )

Nope, the WAR is not 802.3af, you have to use passive, proprietary injectors.
IMHO that's the only objection to WAR hardware I can see, some customers (mostly corporates) like to see 'af' hardware, but as a WISP, it should not be an issue unless you have hugely long cables.
The other one to watch, 'af' was never designed to run outdoors, there are no surge suppressors (other than esd) on kit such as netgear switches. In a tower scenario, i'd be a bit concerned, and ethernet surge suppressors should be added. Possibly a passive, proprietary system is less at risk if a belt comes down the wires.
But I'm sure if this board really takes off, someone somewhere will make an 'af' version, or second-best, a 48V non-'af' to allow longer cables.

We opted for POE only and we supply the injector.
