[Asterisk-Users] Linksys SRW224P POE Switch

[Lacy Moore - Aspendora]

I was just about to suggest the Powersense module that Cory mentioned.  And
no, the G models do not support 802.3af.

Cory, there was some discussion about just doing the cable only works on
"dumb" poe injectors, not the ones that only send power if requested.  I was
under the impression the Linksys only sent power if requested, and if that
was the case only the Powersense would work.  Admittedly, I have not tried
the cable only approach.

The discussions were all from this list several months ago.  There was also
someone that said the cable that converts standard POE to use for the
Polycom non standard POE phones would work as well.  I haven't tried this
yet either.

I may do some experimenting today.  Guess I should locate my oldest 7960
first, in case there are sparks and a fire :-)
