So last year I had a Sonicwall NSA 5650 security appliance crash. I couldnt log in, or load the settings. So I had to order a new one to replace it, thinking the circuit board was fried from the sudden power outage we had (i didnt have it on a UPS). I had decided to take the bad one home instead of sending it off to E-waste. I just powered it on, still couldnt log in. Reloaded factory settings.. guess what... its still good.. its a 6k dollar piece of equipment..
