AFAIK, Surge Protectors usually have those circuit breaker reset buttons on them (since they are supposed to break the circuit when it detects a power surge). However, and I'm no expert by any means, it is my understanding that the standard $15 surge protectors you can buy at Walmart or Home Depot are not really going to protect your network from serious surges. You're better of spending $75-$100 for a decent UPS (Uninterruptable Power Supply) which includes surge protection (I recently bought two from APC for my home network myself).
But going back to your original question, I *think* you need to look for that circuit reset button to distinguish between power strip and surge protector. Please someone else chime in and correct me if I'm wrong.
