Two similar questions:
Surge suppressors can blow ports. If you have a surge, the surge protector
will clamp all the Ethernet lines to ground. That shorts them all together and
grounds them. That will also blow some POE ports.
So you need surge protectors to protect things from surges, but you need fuses
to protect the POE source from the surge protector. Learned this the hard way.

So for a Netonix, do we just need the fuse or do we need the surge arrestor
card as well?

per chuck they must be fueses to protect a netonix, anything else was too

I'm sure you already thought about this, but is it possible to make a
device that recovers automatically after the short circuit has ended while also
responding fast enough to protect the port?
Is it a case where it's possible but costs too much?

We have been shipping for months.
The cost of having a Netonix port repaired is more than the cost of the
fuse.
And then there is the labor and downtime and other intangible expenses
involved in blowing a port.
The prices are lower if you buy from one of my distributors. I don't
encourage anyone to buy off my ecommerce site and pay full list price. That
site is only there to generate sales for distributors.
All of my products have prices based on cost plus margin. Same formula
across the board pretty much. I try to have unique products you can't get
other places. If volume increases on a product, I sometimes adjust the price
down due to the fact that my costs come down. For example, if I am buying 1000
surge protector PCBs, I may be paying $1 for each. But if I am only buying 100
of them it may be $2.50.
I recently adjusted the cost down on my 8 circuit tower surge protector
for exactly this reason. Volume picked up, I worked on sourcing and buying and
was able to drop the list price considerably and still maintain my margins.

Hi Chuck,
Great to hear about the new product, the POE Fuse.
Question & critique.
When are these going to be available ?
We would like to see these priced a bit more aggressive...
(At the current pricing, the cost of fusing multiple ports appears to be
exceeding the cost of 'poe switch' it is protecting ! )
Regards.
