Observe the port status LED.
• The LED turns green when the switch and the other 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 other device might not be turned on, there might be a cable problem, or there might be a problem
with the adapter in the other device.

The ports provide PoE support for devices compliant with IEEE 802.3af and 802.3at (PoE+), and also provide
Cisco prestandard PoE support for Cisco IP Phones and Cisco Aironet Access Points.
On a per-port basis, you can control whether or not a port automatically provides power when an IP phone
or an access point is connected.
