Harrar 0 Posted February 8, 2010 Found this one. Haven't tried it myself but it has possibilities for future use. http://www.directindustry.com/prod/korenix-technologies/industrial-ethernet-switch-card-29418-410948.html Share this post Link to post Share on other sites
Soundy 1 Posted February 9, 2010 Found this one. Haven't tried it myself but it has possibilities for future use. http://www.directindustry.com/prod/korenix-technologies/industrial-ethernet-switch-card-29418-410948.html I'd be pretty leery of that - I don't see a power connector on it, meaning it would have to pull +12V and -12V from the PCI bus to get the 24V that it then uses to step up to 48V. That's a lot of current to be drawing from the motherboard, even assuming 100% efficiency in the conversion. Looking at a 500W Antec PSU I have sitting here, the -12V rail is only rated to a maximum 0.8A, which means you'd have a MAXIMUM (again, assuming 100% efficiency) of 19.2W available, which is barely enough to drive ONE device to spec, never mind two.

Soundy 1 Posted February 9, 2010 ^I call BS on that. They state a full 15.4W *per port*... there's no way it will do that all at once. One port at a time, MAYBE. MAYBE. The page states the card starts with 24VDC and steps it up. The only place it can get that 24V from a PC power supply is using both +12 and -12V rails together. The PDF says it uses the ATX 4P power connector (uh, and what if your motherboard needs it???), which doesn't have -12V on it. And as noted above, even on a 500W Antec supply I have here, the -12V rail is only 0.8A *max*. They may be good stepping up from 12V, as the PDF suggests (contrary to the page Harrar linked to, which states only a 24V supply), but not from 24... It's a nice idea, but there's something fishy in all that. Share this post Link to post Share on other sites

I will call today and get some pricing I'd be interested to see how that works out under FULL load - this sort of cheap offshore stuff, I'd expect to find that they're counting on 99% of devices it will be used with, not needing anywhere near the full 15.4W. Kind of like the "200W" car amp my buddy bought once, that had a 10A power fuse - even at 100% efficiency and assuming a full 14.5V, you CAN'T get more than 150W without blowing the fuse... nevermind that a typical cheap Class AB amp is only about 40% efficient. Yet somehow they manage to claim that it does 200W output power... Share this post Link to post Share on other sites

Soundy 1 Posted February 9, 2010 So does the spec sheet or anything list a minimum PC power supply requirement? Considering some of the systems I've seen (5-6 drives in a machine with a 300W PSU), you'd want to be careful about what you're adding that extra 70W load to.

robert 0 Posted March 22, 2010 Does anybody have any experience with or know of a 4 port PCI-X network card with POE output? Why do you need one? What stops you using PoE router? Share this post Link to post Share on other sites
hardwired 0 Posted March 22, 2010 Nothing prevents the possibility of using a PoE switch or midspan (haven't seen many PoE routers, though, except for some really high end stuff from Adtran and 3Com). I think the idea was to build an all-in-one solution for a small system, would make it a little more plug and play for a end user, too. Share this post Link to post Share on other sites

robert 0 Posted March 22, 2010 Its definitely more clean install, but world famous brand usual PoE switch vs unknown brand PCI PoE card. What do you think? If its 275$, then price is similar to Netgear/Trendnet 4 port PoE switches. Share this post Link to post Share on other sites
