PoE? What's that?


Proably this

http://en.wikipedia.org/wiki/Power_over_Ethernet

but what it has to do with a Pi I have no idea..but then it is dennis
who said it, so its pretty much guaranteed to be more or less a techno
wamk fantasy of some sort.

Dennis likes to drop these this in so he can tell you about something
he read about yesterday...

On the other hand ot might be this

http://rationalwiki.org/wiki/Poe%27s_Law

which would seem to apply to what dennis laughingly refers to as his
mind.


Just for once, Dennis got something right. The first batch of Rasperry
Pis were made with non-isolating ethernet sockets, and applying Power
Over Ethernet would fry the board. So they had to delay release while
the factory installed the correct sockets with the built-in isolating
transormer.


No, Deniis still dint get it right.

He said 'the Pi'. Not 'Pis' or 'your Pi' or 'the Pis' any of which
might refer to one or more rasberry Pis. No, he used the term 'the Pi'
which has only one meaning outside of discuussion of a particular board
(which we weren't') and that is the whole company or concept of Rasberry
Pis. And it would be hard to imagine them dying..juts on account of a
batch of faulty production units,.

Secondly if you bother to THINK about it, one thing you can be 100%
sure of in todays H & S culture is that whatever else may or may not be
inside a PoE adapter some way of making sure than mains voltages do not
appear anywhere on the RJ45 socket is likely to be one of them.

So its more likely than not that PoE will actually be far far less
likely to fry one of the faulty units.

Dennis has succeeded in making you take a casual glance and speak
without thinking in his defence: You must be relatively new here or you
would have learnt that the default stance is that anything dennis says
is wrong or ill conceived and understood or badly expressed.

The rare occasion that he is in fact right is usually over something so
well known and trivial, it's not worth commenting on.
