Re: [WISPA] POE powered POE Splitter with Switch?
I have also built my own POE board like that. My cost was around $75 in parts and spare time over 3 days. We do not have enough need to do the integrated switch but did look into sourcing some hardened switches and modifying them.

Re: [WISPA] POE powered POE Splitter with Switch?
3Com was close with the Network Jack devices. made to fit in a wall outlet, poe, POE out, and 300 version was managed. Only four ports out, but initial testing was pretty cool. It is only 802.3af. nj200 is the 10/100 model, and I just googled it and there is now a nj2000 for Gigabit speeds.

Re: [WISPA] POE powered POE Splitter with Switch?
A quick google search turned up this: http://www.wirelesslan.gr/product_info.php?cPath=48products_id=1062osCsid= 440557bb417622d46a58ff9007e2a706 POE switching volt to 5V or 6V or 7.5V or 9V or 12V Looks to be 48V in and two outputs of 5V, 6V, 7.5V, 9V, or 12V. It would require a fairly large case at the top side of your tower, but you could run 48V up a single 4 pair ethernet cable to a 3COM NJ200 - then you could run 48V out of the various ports of the NJ200 into these little voltage regulator devices and then run the regulated 12V power out of these devices and into your top side equipment. Theoretically it would work and you would have a network switch topside all running off of a single 4 pair wire. NOTE: I wouldn't do this! I would just run extra pairs to the top. The less equipment topside the better. Too many circuits top-side makes too much climb time. Stuff breaks... I think Murphy's law has some sort of postulate that says stuff at 200ft AGL breaks MORE OFTEN!!! - Larry -Original Message- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Greg Ihnen Sent: Tuesday, March 16, 2010 12:35 PM To: WISPA General List Subject: Re: [WISPA] POE powered POE Splitter with Switch?
