Maybe 10 for link partner ? Please no, 30 seconds is way too long for "your mains power is knackered, please fiddle with the power connector again" notification. When I jiggle the wire I need to know if it's making contact within 1 second, and if it's lost when I let it go, I need to know that within 1 second so I can jiggle it some more. Probably should try some contact cleaner ;-) Thanks... -- Jamie
