We want to talk about four The first is power over Ethernet or PoE Next is Voice VLAN, a key feature Link Layer Discovery Protocol has two parts: LLDP and LLDP-MED We’ll go over each of these briefly Course SSEX02B © Juniper Networks, Inc EX Series Technical Details Slide Components of Power Over Ethernet (PoE) • Two primary components of a PoE deployment: • Powered device (PD) that accepts and utilizes delivered power • Power sourcing equipment (PSE) such as an EX2200, EX3200 or EX4200 Series switch EX2200-24P-4G 24 ports PoE EX2200-48P-4G 48 ports PoE EX3200-24T- ports PoE* EX3200-48T- ports PoE* EX3200-24P- 24 ports PoE* EX3200-48P- 48 ports PoE EX4200-24T- ports PoE* EX4200-48T- ports PoE* EX4200-24P- 24 ports PoE* EX4200-48P- 48 ports PoE* • EX2200 Series EX3200 Series EX4200 Series * Enhanced PoE support EX with Junos 11.1 update © 2011 Juniper Networks, Inc All rights reserved CONFIDENTIAL SSEX02B www.juniper.net | There are two primary components of power over Ethernet One is a powered device, meaning a VoIP phone, access point, video camera, or other device that requires power from power-sourcing equipment The other is that power-sourcing equipment, which, in our case is the EX2200, EX3200 or the EX4200 Series of products This slide shows the model numbers, the number of ports, and the number of PoE ports provided Remember that there is no power management and no additional configuration on the power-sourcing equipment You can plug a powered device into a PoE-capable port on the EX Series switches If that device negotiates power, that’s fine If it doesn’t, it gets the full 15.4 watts of power You don’t need to worry about having a limited power budget on that device and having to portion out that power budget on a port-by-port basis Enhanced PoE will be supported in the 11.1 release of Junos for the EX3200 and EX4200 models that support PoE This will deliver 18.6 watts per port Customers who are familiar with other vendors’ product lines sometimes ask, “How you power management?” or “What power management is available on the device?” or “How many ports of PoE you have?” The answers are very simple: we have no power management because we don’t need it, we provide power on every port, and all ports are powered Course SSEX02B © Juniper Networks, Inc EX Series Technical Details Slide PoE Considerations (1 of 2) © 2011 Juniper Networks, Inc All rights reserved CONFIDENTIAL SSEX02B www.juniper.net | 10 When selecting products to meet requirements you must factor Power over Ethernet (PoE) into your selection process PoE ports provide electrical current to devices through the network cables so that separate power cords for devices such as IP phones, wireless access points, and security cameras are unnecessary Full PoE models (Class PoE on all ports) are primarily used in IP telephony environments Partial PoE models (only of the ports supply PoE) such as some of the EX3200 and EX4200 models, are used in environments where, for example, only a few ports for wireless access points or security cameras are required PoE was first defined in the IEEE 802.3af standard In this standard, the amount of power that can be supplied to a powered device is limited to 15.4 W A later standard, IEEE 802.3at, defined PoE+, which increases the amount of power to 30 W The PoE+ standard provides support for legacy PoE devices—an IEEE 802.3af powered device can operate normally when connected to IEEE 802.3at (PoE+) power sourcing equipment When selecting a switch to supply PoE power you will need to know the PoE Class of each device being powered and how many total devices you are connecting This will establish the PoE budget that is needed Each switch capable of delivery PoE power has a PoE budget which is the maximum amount of PoE power it can deliver Another consideration is redundant power within the switch This can provide the benefit of power redundancy in case of a power supply failure, data will still flow and devices will maintain power Also, the power supplies will share the load of powering the switch and PoE devices, extending the lifetime of the power supplies Course SSEX02B © Juniper Networks, Inc EX Series Technical Details Slide 10 PoE Considerations (2 of 2) * EX2200 is also available in non-PoE models **EX3200 and EX4200 port models use the first eight ports on the switch to supply PoE ***DC versions not supply PoE © 2011 Juniper Networks, Inc All rights reserved CONFIDENTIAL SSEX02B www.juniper.net | 11 EX Series switches with PoE ports support either IEEE 802.3af or IEEE 802.3at The EX3200 and EX4200 switches support IEEE 802.3af; the EX2200 switch supports IEEE 802.at (PoE+) Starting with Junos operating system release 11.1, we will provide enhanced PoE on EX3200 and EX4200 switches Enhanced PoE is the Juniper Networks extension to the IEEE 802.3af standard that allows up to 18.6 W per PoE port Here is a breakdown on PoE capabilities in Juniper products: EX2200 switches are available with full (all 24 or 48 built-in ports) or no PoE capability EX2200 switches running Junos release 10.3 or later can supply up to 30 W to individual PoE ports, supporting powered devices that comply with IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) EX3200 switches with an AC power supply installed have options of full (all 24 or 48 ports) or partial (8 ports) PoE capability EX3200 switches with a DC power supply installed not provide PoE EX4200 switches with an AC power supply installed have options of full (all 24 or 48 ports) or partial (8 ports) PoE capability EX4200 switches with a DC power supply installed not provide PoE PoE is not available on the following models: The EX4200-24F, EX4500, EX8200 Series, and QFX3500 switches Course SSEX02B © Juniper Networks, Inc 10 ...
