When making a cable umbilical cord coming off the back of a rack, should the audio + data + control cables be bundled separately from the power cables to the rack PDU ?
If you can do so, yes. The installations I've seen with a lot of power cable to stow were done on racks that had about three inches of empty width outside the rack rails. Power cabling was stowed in that space. That's a good idea since you then don't have to worry about getting custom length power cables. Also, jamming cables into that space gives you at least a slightly random arrangement of wires, with randomness being less conducive to noise ingress than nicely arranged wires are.
When dressing the cables into the back of the rack should one side of the rack be used for audio + data + control cables and the other for power cables ?
If you can do so, yes. Wouldn't it be nice if manufacturers decide on a side to ALWAYS use for power?
