Connecting to the PoE Ports

The 10/100 PoE ports have the same autonegotiation settings and cabling requirements as those in the

connectors.
The ports provide PoE support for 802.3af-compliant devices 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 to a connected
IP phone or an access point.
To access an advanced PoE planning tool, use the Cisco Power Calculator on Cisco.com:

You can use this application to calculate the power supply requirements for a specific PoE configuration.
The results show output current, output power, and heat dissipation.
Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if
