I have a DSL modem with the power adapter for the modem plugged into a surge protector. The phone line going into the modem is not surge protected. (I don't really care about the modem because it's a cheap piece of equipment that came with my internet service.) The thing is, I don't use the wireless function of the modem, but I use a ethernet cable from the modem directly to my MacPro. Should I be running this ethernet cable through a surge protector first, and then plugging it into my MacPro? It just dawned on me that I wasn't doing this. And I was wondering if my motherboard or something could get fried in an electrical storm if I don't do this? I would hate for something like this to happen to my precious.
