On several occasions, after storms, I've had to revive a locked up series 4 processor. Each time it has involved me calling tech support, telling them what the LED status lights on the processor was doing and being asked to flip a dip switch or two and power cycling and voila, the processor is unstuck from boot mode or a link is free. It seems like magic but I'd like to be able to do that without having to call tech support (everybody's time is money after all) so is there a pdf of the LED's somewhere? I didn't see it on resi and the tech support people said no which seems kind of odd. Is it because one can do some damage with the dip switches?
