tl;dr:
How do I find out the specification of any ribbon cable, like diameter, resistance, and so on?
I recently bought a DRAC (Dell Remote Access Controller) for my PowerEdge2900 off ebay today. But as I just noticed (sadly after ordering) the bus cables will be too short to reach my motherboard since the cables delivered are those for the rack version. But since plugs do remove pretty easy from ribbon cables I plan to enlarge them. Given that I do not have the card yet, I would like to know what kind of ribbon cable I will need to do that, since I know there are different thicknesses of wires. Maybe someone with a DRAC is able to tell me.
