Current Sharing Techniques for High Power PoE Applications
Low-cost application note describing how to build a
High Power over Ethernet PD interface for the most
common case, where a High Power PD is powered by a High
PoE switch, or by a High PoE Midspan. Each PoE port has
a common voltage source for all the power fed to it.

Powering PDs with High Power Requirements (HPDs)via High Power over Ethernet (HPoE)
This application note will explain and exemplify the design
of a PD (Powered Device) power front-end that relies on
provision of high power over Ethernet. It is aimed at
engineers who wish to equip new generations of high power IP
phones, WLAN or Bluetooth access points, LAN controlled
security cameras and other Ethernet controlled terminals
which require HPoE capabilities.

Software Download to PowerDsine Power over Ethernet Unit
This application note describes the way to download new
software version to PowerDsine's integrated solutions as
chipset MCU, SIP controller and DIMM controller, serving as
an independent Power over Ethernet (PoE). The download is
done via the RS-232/UART I/F after implementing a S/W
bridge on the customer's host CPU.

Designing a Low-cost IEEE 802.3af PD (Powered Device) Front-end
What does it take to construct or modify a networked
device so that it becomes PoE-ready? That's what this
application note will explain, while exemplifying the
design of a PD (Powered Device) power front-end, which
complies with the IEEE 802.3af Power over Ethernet (PoE)
standard.
The target audience for this application note includes
engineers who wish to equip new generations of IP phones,
WLAN or Bluetooth access points, LAN controlled security
cameras and other Ethernet controlled terminals with PoE
capabilities.

Classification Feature In Power over Ethernet Systems
This document describes the Classification feature in Power over Ethernet (PoE)
devices and systems and its implementation in the Power Sourcing Equipment
(PSE). As defined in IEEE 802.3af-2003 standard, this feature enables the
PSE to forecast the power to be consumed by the Powered Device (PD)
connects to it and classify it accordingly.

AC-Disconnect Feature In Power over Ethernet Systems
This document describes the AC-Disconnect feature in Power over Ethernet (PoE)
devices and systems and its implementation in the Power Sourcing Equipment
(PSE). As defined in IEEE 802.3af-2003 standard, this feature enables the
PSE to shut down power supply to a PoL channel, on a sudden load
disconnection, thus protecting non-PoL devices connected to the same
channel right after disconnection.
