When you plug your Time Capsule into a power outlet, the status light flashes green
for one second and then glows amber while your Time Capsule starts up. After your
Time Capsule has started up completely, the status light flashes amber until your Time
Capsule has been updated with the correct settings. The status light glows solid green
after your Time Capsule is properly set up and connected to the Internet or a network.
When you connect Ethernet cables to the Ethernet ports, the lights above them glow
solid green.
