ProC2520-24PoE

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.

2. Reference Configuration

As illustrated in Figure 1, the Avaya PDs covered in these Application Notes include the
following:

 Avaya 9600 Series IP Telephones
 Avaya 5600 Series IP Telephones

 Avaya 1600 Series IP Telephones

For compliance testing, the Avaya 1600/9600 Series IP Telephones registered to Avaya Aura

Communication Manager and the Avaya 5600 Series IP Telephones registered to Avaya IP
Office.
