When a device is connected to a port, the port-status LED light comes on
and stays on. If the light does not come on, the other end might be off, or
there might be a cable problem. Also, if a light goes on and off, there is a pos-

next section. If you do not have a device connected to the switch, the port
light will come on when booted, then it will turn off.
