I'm recently in a "home network upgrade" / "rack rebuild" / "my wife will kill me for what I've spent money for" situation and I'm thinking...
I have in my rack:
gigabit switch
Cisco WAP (outside, but powered from rack)
ISP router
QNAP 2-bay NAS
All these compnents are running on 12V DC power, from it's own power source and I'm wondering... why not to run them all from one power source ?
There are high efficiency power sources available on the market built for such use. Not to mention that they are usually more efficient (then network equipment original power sources) and some of them also provides ability to hook up 12V lead-acid backup battery for UPS function (not needing to use actual UPS as we don't need 220/110 AC power). For example DIN mountable: http://www.meanwell.com/webapp/product/search.aspx?prod=DRC-60
Only downside of this setup would be single point of failure which is - for home use - not that serious as I can replace the power source within one day easy.
Is there anyone who done this before ? I will post progress, but it would be best if I can gather some thoughts on this before investing a lot of money
Thanks a lot.
