Cisco Networking Innovation Delivers More PoE to Wide Range of Enterprise Devices
Cisco announced what it says is the industry’s first 60W Power over Ethernet (PoE) capability for one of the most widely deployed enterprise class switches in the industry, the Cisco Catalyst® 4500E Switch. Powering communications and IT devices via Ethernet cables instead of a main electricity supply can reduce power consumption during times when devices are not being used. This can help lower the total cost of IT operations and contribute to organizational corporate sustainability targets.
Cisco states that its Universal Power Over Ethernet (UPOE) can offer twice the power per port over products from competing switch vendors and provides both power and network access to a greater range of devices through a single standard Ethernet cable.
Additionally, Cisco announced that Samsung zero client desktop virtualization devices and BT IP turrets have integrated Cisco UPOE technology into their devices to allow customers the immediate advantage of using their existing Cisco network to power these solutions.
By using Cisco’s new UPOE linecard and UPOE splitter, any device requiring up to 60W power can now be powered by Cisco’s Catalyst 4500E Switches. This includes Cisco IP phones, personal telepresence systems, compact switches and wireless access points.
Cisco Universal Power Over Ethernet can be combined with Cisco EnergyWise to extend the capability of energy administration and policy setting beyond the traditional PoE devices via simplified network and power cabling infrastructures. By simplifying network infrastructures and reducing power consumption, enterprises can lower the total cost of ownership of IT while improving corporate sustainability.
Cisco Universal Power Over Ethernet is available now with a new linecard on the Catalyst 4500E. Up to 120 UPOE ports can be supported in a single Catalyst 4500E chassis. Cisco Universal Power Over Ethernet utilizes standard Cat 5e or higher cabling and RJ45 connectors to enable an easier deployment of this solution within existing infrastructures.
In September 2011, Cisco will ship a Universal Power Over Ethernet splitter, which will allow connections to additional third-party devices with a standard DC output.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
