mused:

You're not supposed to run data cables close/parallel to power cables.
If the office has a suspended ceiling you could just run long patch
cables over it (avoiding cables to lighting) and let them dangle.

Bugger, better go and rip out those thousands of miles of cat5's I've
put in in segregated dado trunking in close proximity and parallel to
power then.

Better had then :-)
