Power over Ethernet overview

This section provides an overview of the requirements for delivering power over the LAN, as defined
by the Institute of Electrical and Electronics Engineers Inc. (IEEE) in the 802.3af (PoE) and 802.3at
(PoE+) specifications.

Brocade PoE devices provide Power over Ethernet, compliant with the standards described in the
IEEE 802.3af specification for delivering inline power. Brocade PoE+ devices are compliant with both
the 802.3af and 802.3at specifications. The 802.3af specification defined the original standard for
delivering power over existing network cabling infrastructure, enabling multicast-enabled full streaming
audio and video applications for converged services, such as, Voice over IP (VoIP), Wireless Local
Area Access (WLAN) points, IP surveillance cameras, and other IP technology devices. The 802.3at
specification expands the standards to support higher power levels for more demanding powered
devices, such as video IP phones, pan-tilt-zoom cameras and high-power outdoor antennas for
wireless access points. Except where noted, this document will use the term PoE to refer to both PoE
and PoE+.

Power over Ethernet

on page 261 lists the FastIron devices and modules that support PoE, PoE+, or

both.

PoE technology eliminates the need for an electrical outlet and dedicated UPS near IP powered
devices. With power sourcing equipment such as a BrocadeFastIron PoE device, power is
consolidated and centralized in the wiring closets, improving the reliability and resiliency of the
network. Because PoE can provide Power over Ethernet cable, power is continuous, even in the event
of a power failure.

Power over Ethernet terms used in this chapter

The following terms are introduced in this chapter:

Power-sourcing device or Power-sourcing equipment (PSE) - This is the source of the power, or

the device that integrates the power onto the network. Power sourcing devices and equipment have
embedded PoE technology. The BrocadeFastIron PoE device is a power sourcing device.

IP powered device (PD) or power-consuming device - This is the Ethernet device that requires

power and is situated on the end of the cable opposite the power sourcing equipment.

Methods for delivering Power over Ethernet

There are two methods for delivering Power over Ethernet (PoE), as defined in the 802.3af and
802.3at specifications:
