The only trick is that these pins should be hooked up to a momentary contact switch - which makes sense. Think about the power button on your PC: you push it in, it pops right back out, and your PC starts to boot. So to simulate that behaviour without a switch, you just need to short the two pins briefly. I used a pair of needlenose pliers to push the jumper down and then immediately pull it off. Thanks to Brian for pointing this out.
