Power over Ethernet

� Power over Ethernet or PoE technology describes a system

to transmit electrical power, along with data, to remote

devices over standard twisted-pair cable in an Ethernet

network.

How to Deploy Power over Ethernet (PoE)

Power Sourcing Equipment

(PSE) (such as a Cisco

Catalyst LAN Switch Port)

There are two primary components of a PoE deployment:

Powered Device (PD)

Inserts power over the Ethernet cable

Accepts and utilizes delivered inline power

Understanding Power Redundancy

The 4500 can utilize two power supplies to work in either combined or redundant mode

Redundant Mode Combined Mode

Switch

Switch

© 2009 Cisco Systems, Inc. All rights reserved. Cisco Confidential4500 Bootcamp 7

In redundant mode, each power supply operates at 50% capacity and provides the same total power as a single power

supply – if one fails, the backup reverts to providing 100% power

In combined mode, each power supply operates at 83% - if one fails, then the

running supply provides 100% of its power capacity

1. System log and SYSLOG messages generated

2. System power is increased to 83% for both supplies, this providing 167% of power supply total capacity

3. If any modules were marked power deny due to insufficient power will be brought online if enough power is available

2. System power is decreased to power of one power supply - each power supply would normally revert to 50% operational capacity

3. If module configuration exceeds available power, modules powered down from bottom slot upwards – inline devices are powered down from highest port to lowest port until power requirement is within available limits

Definition of Enhanced PoE

–Delivers higher power than 802.3af (Class 3, 15.4W) but up to 20 Watts/port

–This is a Cisco proprietary standard and is not IEEE 802.3at/POEP

Example:

Operation when AP1250 is plugged into a Cisco switch

Enhanced PoE (ePoE)

© 2009 Cisco Systems, Inc. All rights reserved. Cisco Confidential4500 Bootcamp 19

1. AP boots up as a class 3 device2. Switch and AP auto-negotiate a higher

power level using CDP3. If the Switch cannot provide adequate

power, then the radios remain OFF AP1250 C4500-E

A dual-radio AP1250 with one radio disabled draws higher power than 802.3af can deliver!

� IEEE802 created in December 2004 a study group called PoEPlus

� PoE+ has turned into 802.3at(http://www.ieee802.org/3/at/ )

� The objectives approved in September 2005 as binding for the IEEE802.3at Power over Ethernet Enhancements Task

Evolution of the IEEE 802.3atPoE Standard

© 2009 Cisco Systems, Inc. All rights reserved. Cisco Confidential4500 Bootcamp 21

the IEEE802.3at Power over Ethernet Enhancements Task Force:

802.3at should operate on CAT5E and higher infrastructure.

A High Power 802.3at PSE must be backwards compatible with 802.3af, being able to power both 802.3af and 802.3at PD's

802.3at should provide the maximum power to PD's as allowed within practical limits, at least 30W

802.3at PD's, when connected to a legacy 802.3af PSE, will provide the user an indication that an 802.3at PSE is required.

There are three main areas where the switch interacts with the Cisco IP Phone – they are in the areas of delivery of inline power, VLAN tagging, and extended trust settings.

Voice Traffic needs are different to normal Data – it is more latency sensitive and is not as tolerant of packet drops. For this reason, most design guides advocate separating Data and Voice traffic into separate VLAN’s. The Auxiliary (Voice) VLAN is designed to carry Voice only traffic

Data VLANAuxiliary (Voice) VLANStrict Priority Queue

Understanding Auxiliary VLAN’sWhy the need?

© 2009 Cisco Systems, Inc. All rights reserved. Cisco Confidential4500 Bootcamp 28

Keeping Voice data separate from normal Data reduces contention and potential for packet drops, as well as improving latency - CDP is used to instruct the Phone to use the Auxiliary VLAN

Normal QueueNormal Queue

�EnergyWise Importance is a way to differentiate between devices in the domain.

�Importance ranges from 1 to 100

�Importance is used to select devices you want to query or set.

�An office phone has lower importance as compared to a business critical or emergency phone.

�It is critical the emergency phone never go into a sleep mode

�Emergency phone’s importance is set to a value of 100

� By knowing the importance of connected devices, we can then determine the relative importance of our switches in the network.

Queries: Setting Power in the Domain

A Query command can be used to set power levels in the Domain. In this example, the power level is set to 10 (on full) for all devices with any name that have a importance of 50 or lower. Individual devices with specific names or keywords can also be specified, including wildcards for part of the name or keyword.
