Step 4 Observe the port LED.

• The LED turns green when the switch and the target device have an

established link.

• The LED turns amber while the STP discovers the network topology and

searches for loops. This process takes 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 problem with the adapter installed in the

target device. See Chapter 5, “Troubleshooting the Installation,” for solutions

to cabling problems.
