So, what's the fuzz here?
(Don't you all use -48Vdc in telco pops?)
--Peter
The fuzz is that most people use AC supplies in their CSUs and routers. My best guess would be that it's so that they could move those boxes out of the telco environement (if needed) and run them on AC.
You can swap the PS in any cisco box, on some models you don't even need a screw driver. As someone already pointed out, it takes half the components to do UPS -48V than UPS 110V/230V. Where I live the comercial power is more reliable than the small UPS boxes, so the lesson is, UPS'es has to come in pairs.. --Peter
