Perhaps someone from this august list can offer a clue here.

Have:  Cisco 3524-PWR  (paleo-POE, pre-802.3af Cisco standard).

It runs the 7960Gs great.

Have:  Wireless AP stuff that wants 12v on the unused pairs for
passive POE.  48v will let the magic smoke out.

Might buy:  phone that does 802.3af

Want to run these with the 3524-PWR.

I can't imagine that nobody makes a bump-in-the-wire converter for
this application, but haven't been able to find anything other than
802.3af to the passive POE use case.

Anyone got a pointer for me?

Thanks,
