Observe the port status LED.
The LED turns green when the switch and the target device have an established

The LED turns amber while STP discovers the network topology and searches for

If the LED is off, the target device might not be turned on, there might be a cable

See Chapter 3, "Troubleshooting,"
Reconfigure and restart the switch or target device if necessary.
