Power Supply Requirements
     
    
        Follow these recommendations when you plan power supply connections for your
            equipment:
        
            - Place the equipment in an area that accommodates the power
                consumption and component heat dissipation specifications.
- Be sure that your power supply meets the site DC power or AC
                power requirements of the network equipment.
- When you connect power to installed equipment, do not make this
                connection through an extension cord or power strip.
- If your switch includes more than one power supply, connect
                    each power supply to a different, independent power source.
                If a power source fails, it will affect only the switch power
                    supply to which it is connected. If all switch power supplies are connected to a
                    single power source, the entire switch is vulnerable to a power source
                    failure. 
- In regions that are susceptible to
                electrical storms, plug your system into a surge suppressor.
