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.
Connecting to 1000BASE-T SFP
When connecting to a 1000BASE-T device, be sure to use a four twisted-pair, Category 5 or higher cable.
The automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by default. For
configuration information for this feature, see the switch software configuration guide or the switch
command reference on Cisco.com.
