We had a power surge in the whole building which has tripped the blew the main incommer and has sadly taken out one of our managed switches with it. Weve managed to get things back up and running and just about have enough ports on the others to sort it but moving forward I want to put something in the rack that would mean this sort of thing wont happen again. Can anyone anyone recommend a product I can look into or if you need anything more information I can supply any.
