    Glossary
    
    Power Sourcing Equipment (PSE)
        These are devices supplying electrical power to
        other equipment. They are, for example, inline power
        switches, inline power daughterboards and power patch
        panels.
    
    Powered Device (PD)
        These are devices receiving their electrical power
        supply from Power Sourcing Equipment. They are, for
        example, IP telephones and wireless access points
        or bridges.";
