POE bump-in-the-wire conversion

Fri Dec 31 17:49:19 UTC 2010

I was aware of this device (being a big Ubiquiti fan), but have yet to
find anyone who has direct experience with using them on a 3524-PWR.

Have you actually tried this (on a 3524-PWR, not a 3550 or anything
later-but-pre-standard)?  The equipment will be quite happy with
16v...
