Its ALWAYS on the wiki :)

Good question, but the  7940 is NOT a proper 802.3af (POE) device.  It
is a polarity problem, which can be fixed with a crimp tool.

With 1 minute of  crimping I have seen them work with the DLINK
injectors.

Cheers

Cian

Subject: [Asterisk-Users] cisco poe

I know this is on the wiki, I just want to confirm so I don't blow up my

cisco phones.  I've got several cisco 7940's all running using cisco 
power cubes.  However, my boss wants me to switch just a few over to 
poe, but doesn't want to fork out the dough for a nice cisco poe switch,

or anybody else's poe switch for that matter.

So my question is, what is the '99.999% sure/safe' poe injector solution

that most people are using for the cisco phones?

Right now I'm looking at buying the 3-Com 3CNJPSE (qty 2-3) to power the

few specific locations where a power cube just wouldn't look right, like

a conference room table for example. :)  I know this solution, thanks to

the fact that it is a 'hack', is far from the 99.999% I just stated, but

  it also seems to be the only low-end solution for poe.  Am I right, or

just plain blind?

Thanks,
Chris
