Now it's time to get connected. Position your system unit so that you easily can access all the connections on the back, and carefully run the cables from each of the other components so that they're hanging loose at the rear of the system unit.

Connect in Order

It's important that you connect the cables in a particular order. To make sure that the most critical devices are connected first, follow the instructions in Table 2.1.
