1.  Introduction 
Power over Ethernet (PoE) allows both power and data to be simultaneously carried over 
standard Ethernet cables.  PoE-enabled Ethernet switches can supply power directly to Ethernet 
devices, thereby simplifying installation and removing the need for separate power supplies for 
those devices.  The IEEE 802.3af standard defines the mechanisms for Power Sourcing 
Equipment (PSE), such as PoE-enabled Ethernet switches, to detect, classify, and supply power 
to Powered Devices (PDs), such as PoE-enabled IP telephones.  In the compliance-tested 
configuration described in these Application Notes, the HP ProCurve 2520-24-PoE Switch was 
configured to supply inline PoE to Avaya PDs. The ProCurve 2520-24-PoE Series Switch 
supports the IEEE 802.3af PoE standard as well as the upcoming draft IEEE 802.3at standard for 
Power over Ethernet Plus (PoE+) , which can provide up to 30 W per port.  
1.1. Interoperability Compliance Testing 
The interoperability testing focused on verifying PoE interoperability with the ProCurve 2520-
24-PoE Switch and Avaya IP Telephones.  
The power tests included verification of the following after each powered device was connected 
to the switch:  
 
  Successful boot operation.  
  Connecting a mix of Avaya IP Telephones to the switch, power cycling the switch and 
verifying successful boot operation of the PDs and registration of the telephones.
