Yeah I can see that, it's just a bit verbose to repeat the subject though, and technically unnecessary. It's grammatically correct, but in this case it's a question of what you're used to seeing. "As long as" and "if" mean the same thing here, and are interchangeable, though notice that "if properly configured..." could similarly become the more explicit "if it is properly configured...", it's just more verbose despite carrying the same meaning. The first mention of the subject in either case can be omitted.
That said, I'll change it to "if" anyway because that's what readers are more used to seeing so it won't be as controversial!
