Step 3 Insert the other cable end in an LC port on the target device.
Step 4 Observe the port status LED.
The LED turns green when the switch and the target device have an established
link.
The LED turns amber while STP discovers the network topology and searches for
loops. This process can take about 30 seconds, and then the port LED turns green.
If the LED is off, the target device might not be turned on, there might be a cable
problem, or there might be a problem with the adapter installed in the target
device. See Chapter 5, “Troubleshooting,” for solutions to cabling problems.
Step 5 Reconfigure and restart the target device, if necessary.
Step 6 Repeat Steps 1 through 5 to connect each port.
