A famous one that can happen with some techs is that they make jumpers from solid wire with generic rj45 plugs (yes, I've seen this recently from several folks who should know better). These will last somewhere around a year (long enough to forget when they were installed) then randomly fail from just fan vibration or slight breezes. There are rj45 plugs made for solid wire (have 3 little prongs instead of 2, and they are offset to straddle the wire) but I feel that even these can go bad. I know if the techs are properly educated that this "will never happen" (tm)... (till someone needs a custom-length jumper on a sunday...) (for which, one colo building has an ace hardware with most of the right stuff, but unfortunately most don't). As we all (should) know, all solid-wire cable should terminate in a panel and proper short jumpers (pref. with molded strain-relief) are used for the rest. -- Pete
