In today’s intricately networked and globalized economy, efficient and meaningful collaboration among colleagues, customers, partners, and suppliers is a business imperative. The Cisco TelePresence® EX Series is an all-in-one tool that enables individual contributors and knowledge workers to fluidly move from independent work on the laptop to joining project meetings or larger team telepresence meetings, to problem-solving over shared spreadsheets - all directly from their desks. With the Cisco TelePresence EX Series, the productive power of personal telepresence can be shared throughout the organization with absolute quality and natural collaboration. Figure 1 displays the Cisco TelePresence EX Series.

Power over Ethernet (PoE) has long been considered the most critical innovation to revolutionize and expedite the adoption of IP telephony in the enterprise market segment. The benefits of power resiliency and power efficiency that inline power offers IP telephony can be equally beneficial for the Cisco TelePresence EX Series. IEEE 802.3 standard for inline power provides the mechanism to source up to 30 watts over Cat5e (or better) Ethernet cables. This power envelope is insufficient to power the Cisco TelePresence EX series because of the comprehensive media and user experience that it delivers.

What You Will Learn

This document introduces Cisco Universal Power over Ethernet (UPOE), a technology that extends the inline power sourcing capability up to 60 watts, which can be used to power the Cisco TelePresence EX60 Systems over Ethernet. Cisco UPOE can be easily adopted by customers in their existing deployments since it is supported over standard Ethernet cabling infrastructure that conform to PoE-plus requirements.


A common question asked by customers looking to deploy the Cisco TelePresence EX Series is, “Do I need traditional IP telephones if I deploy the Cisco TelePresence EX Series?”

One of key requirements for enterprise IP telephony is to support emergency 911 types of calls and situations. In order to support this requirement, the infrastructure should guarantee high availability for the phones - both in terms of data connectivity and power connectivity. Wall power cannot be used to satisfy this requirement unless there is instantaneous backup power available throughout the building infrastructure. An alternative to this would be to power the IP telephone using inline powering mechanisms and consolidating the backup power (uninterruptible power supply [UPS], generator etc.) into the wiring closet. This move ensures that the backup power can be sourced only to the critical infrastructure components and this was exactly the reason why enterprise IP telephony became prevalent only after the advent of PoE technology.

The IEEE 802.3 standard for inline power over Ethernet cannot be used to power the Cisco TelePresence EX60 Systems since the power required by these endpoints is more than the maximum power that can be sourced. Many organizations find it prohibitive to deploy both Cisco personal TelePresence endpoints and traditional IP telephones in the enterprise workspace because of the increased capital and operating expenditures associated with effectively doubling the number of endpoints deployed in their infrastructure.

Cisco UPOE aims at addressing this challenge by providing an efficient and effective mechanism to power Cisco TelePresence EX60 Systems using an inline powering mechanism.

Solution and Business Benefits

The Cisco Catalyst® 4500E switching platform is Cisco’s leading modular enterprise-class switch for campus deployments. This platform not only provides line-rate switching to all user access ports but also delivers comprehensive borderless network services critical for collaborative video deployments. These services include, but are not limited to:

   Full Cisco Medianet suite with video IP service level agreements (SLAs), Mediatrace, and Media Service Interface (MSI) proxy support

   High availability with full hardware redundancy and software features such as In-Service Software Upgrade (ISSU)

   Application visibility with Cisco Flexible Netflow (FnF)

   Third-party application hosting with Cisco IOS-XE Software

The Cisco Catalyst 4500E switch platform was the first platform to deliver PoE-plus compliant switches, two years prior to the introduction of the IEEE 802.3 PoE-plus standard. The PoE-plus standard defines the mechanism to source up to 30 watts of power from switches.

The Cisco Catalyst 4500E has reached a new industry milestone by introducing Cisco UPOE. With Cisco UPOE, Catalyst 4500E takes the inline power technology to a new level by dramatically increasing the power sourced by the switch to 60 watts. Cisco UPOE is supported on the Cisco Catalyst 4500 Supervisor 7-E-based systems with UPOE-capable line cards. Cisco UPOE helps extends the benefits of power resiliency, management, and efficiency to a wider range of devices, including the Cisco TelePresence EX Series.

There are several benefits in powering Cisco TelePresence EX60 Systems over Cisco UPOE. Cisco UPOE:

   Lowers operating expenditures by providing network resiliency to a much wider range of endpoints at a lower cost by reducing the number of UPS devices that would otherwise get deployed with the endpoints

   Facilitates faster deployment of new campus access networking infrastructures by eliminating the need for a power outlet for every endpoint

   In combination with Cisco EnergyWise, helps meet corporate sustainability mandates while lowering energy costs

A splitter that replaces the external DC power supply (currently shipping with Cisco TelePresence EX60 Systems) allows the powering of Cisco TelePresence EX60 Systems over Cisco UPOE. This adapter has Cisco UPOE as the input and provides two output interfaces - Ethernet data port and an auxiliary 12-volt DC interface. The basic functionality of the adapter is to split the inline power from the data received on the Cisco UPOE input interface. The power is reduced to 12 volts DC and sourced over the auxiliary output port. The data is passed through to the Ethernet output port. Figure 2 shows how the Cisco UPOE splitter can be used with Cisco Catalyst 4500E switch platform UPOE ports to power an existing Cisco TelePresence EX60 Systems.

Yet another telepresence application that can be powered over Cisco UPOE is the Cisco TelePresence Quick Set. This codec, together with its camera and USB ports, can be completely powered over Cisco UPOE. All the benefits of inline powering, including resiliency for power, energy efficiency, and minimizing deployment and management challenges are extended to this application as well through Cisco UPOE. Figure 3 shows Cisco TelePresence Quick Set

Product Specification: Cisco Catalyst 4500E Switch Platform and Cisco UPOE

Cisco UPOE is being introduced on the Cisco Catalyst 4500E, the most widely deployed modular access platform. Cisco UPOE is supported on Cisco Catalyst 4500 Supervisor 7-E (or later)- based Catalyst 4500E switch platforms with UPOE-capable line cards. The Cisco UPOE splitter WS-UPOE-12VPSPL works with UPOE-capable Catalyst 4500E switch platforms. Figure 4 shows the Cisco Catalyst 4500E switch platform.
