Step 3 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
• If the LED is off, the other device might not be turned on, there might be a cable problem, or there might
Step 4 If necessary, reconfigure and restart the switch or other device.

10/100/1000 PoE+ Port Connections

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.
To access an advanced PoE planning tool, use the Cisco Power Calculator available on Cisco.com at this

You can use this application to calculate the power supply requirements for a specific PoE configuration. The
results show output current, output power, and system heat dissipation.

are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such
interconnection methods, unless the exposed metal parts are located within a restricted access location
and users and service people who are authorized within the restricted access location are made aware of
the hazard. A restricted access area can be accessed only through the use of a special tool, lock and key
or other means of security. Statement 1072
