After you connect to the switch port, the port LED turns amber while the switch establishes a link.
This process takes about 30 seconds, and then the LED turns green when the switch and the target
device have an established link. 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 the
“In Case of Difficulty” section on page 20 for information about online assistance.
