Ethernet at New Speeds, Deterministic Networking, and Power Over Everything! Ethernet Evolving: Ethernet at New Speeds, Deterministic Networking, and Power over Everything! Dave Zacks Distinguished System Engineer @DaveZacks Peter Jones Principal Engineer @petergjones #NBASET BRKCRS-3900 #HighBitrate Ethernet Evolving: Ethernet at New Speeds, Deterministic Networking, and Power over Everything! BRKCRS-3900 – Session Overview We have a great session for you today … so sit back, buckle in, and let’s get started! Come to this session to get geared up on the latest developments in Ethernet for Campus and Branch networks. The Ethernet we all know and love is evolving at a rapid pace. With the release of MultiGigabit Ethernet on Cisco's latest Catalyst access switching platforms, you can connect new devices that support MultiGigabit connections at 2.5Gb/s and 5Gb/s over Cat5e/6 copper. No longer are 1Gbps and 10Gbps the only connectivity options – intermediate speeds are now possible. Cisco’s Multigigabit Technology is a key enabler for upcoming 802.11ac Wave 2 wireless deployments, where the Ethernet bandwidth required per AP exceeds 1Gb/s. Multigigabit switches also support other high-bandwidth devices in the Ethernet access layer without requiring expensive and time-consuming re-cabling for 10GBASE-T. We will talk about how Cisco MultiGigabit switches work, and how they will change your network. As well, we will discuss work being done in (and out of) the standards bodies to broaden the footprint for Ethernet, and enable the Internet of Everything. This includes additional Ethernet speeds, capabilities for deterministic networking functionality over an Ethernet infrastructure (precision timing, pre-emption, time scheduling, etc), and of course we need to provide more Power over Ethernet to more devices, in more places, than ever. Come to the session to get the latest scoop!3 Ethernet Evolving: Ethernet at New Speeds, Deterministic Networking, and Power over Everything! Your Instructors Today … Peter Jones and Dave Zacks • Peter is a Software Principal Engineer, and has been with Cisco for 10 years.

  • Power Over Ethernet
    How To | Power over Ethernet Introduction Power over Ethernet (PoE) is a technology allowing devices such as IP telephones to receive power over existing LAN cabling. This technical note is in four parts as follows: • PoE Technology • How PoE works • Allied Telesyn PoE implementation • Command Reference What information will you find in this document? The first two parts of this document describe the PoE technology, and the installation and management advantages that PoE can provide. This is followed by an overview of how PoE works, Power Device(PD) discovery, PD classification, and the delivery of power to PD data cables. The third part of this document focuses on Allied Telesyn’s implementation of PoE on the AT-8624PoE switch. The document concludes with a list of configuration and monitoring commands. Which product and software version does this information apply to? The information provided here applies to: • Products: AT8624PoE switch • Software version: 2.6.5 C613-16048-00 REV C www.alliedtelesyn.com PoE Technology Power over Ethernet is a mechanism for supplying power to network devices over the same cabling used to carry network traffic. PoE allows devices that require power, called Powered Devices (PDs), such as IP telephones, wireless LAN Access Points, and network cameras to receive power in addition to data, over existing infrastructure without needing to upgrade it. This feature can simplify network installation and maintenance by using the switch as a central power source for other network devices. A device that can source power such as an Ethernet switch is termed Power Sourcing Equipment (PSE). Power Sourcing Equipment can provide power, along with data, over existing LAN cabling to Powered Devices.

Therefore, the POE-E201 is designed as the repeater to forward both Gigabit Ethernet data and high power PoE power, and thus extend the range of PoE installation. By just plug and play without additional power supply and setup, one single POE-E201 can increase the PoE range to 200m. By daisy-chaining multiple POE-E201s, it offers you great flexibility to extend the distance of PoE network to triple, quadruple further in length or more.
