You can use this application to calculate the power supply requirements for a specific PoE configuration. Enter the number and types of powered devices that you plan to attach to the switch, and the calculator shows the PoE or PoE+ power required and the system power consumption.

You must be a registered Cisco.com user to access the Cisco Power Calculator. If you do not have a user ID or password, you can register:

For more information about the required power-supply module and the PoE specifications, see the “Power Supply Modules” section on page 1-17and Appendix A, “Technical Specifications.”

Note Many legacy powered devices, including older Cisco IP phones and access points that do not fully support IEEE 802.3af, might not support PoE when connected to the switches by a crossover cable.

Caution PoE faults are caused when noncompliant cabling or powered devices are connected to a PoE port. Use only standard-compliant cabling to connect Cisco prestandard IP Phones, wireless access points, or IEEE 802.3af-compliant devices to PoE ports. A cable or device that causes a PoE fault must be removed from the network.

Warning Voice over IP (VoIP) service and the emergency calling service do not function if power fails or is disrupted. After power is restored, you might have to reset or reconfigure equipment to regain access to VoIP and the emergency calling service. In the USA, this emergency number is 911. You need to be aware of the emergency number in your country. Statement 361

Warning Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections 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

If the default configuration is satisfactory, the switch does not need further configuration. You can use any of these management options to change the default configuration:

•Start the device manager, which is in the switch memory, to manage individual and standalone switches. This is an easy-to-use web interface that offers quick configuration and monitoring. You can access the device manager from anywhere in your network through a web browser. For more information, see the switch getting started guide and the device manager online help.

•Start the Network Assistant application, which is described in the Getting Started with Cisco Network Assistant guide. Through this GUI, you can configure and monitor a switch cluster or an individual switch.
