Ethernet switches provide dual redundancy of airport refueling control system
For many organisations today, particularly industrial, transportation and buildings management companies, IT infrastructure and related networking technology must operate continuously with minimal downtime or redundancy. Network recovery time is therefore critical.
Ethernet Alliance Webcast to Focus on PoE Plus Applications
The Ethernet Alliance today announces a free educational webcast titled "PoE Plus: Impact on the PoE Market."
Opening the Door to IP POE-Powered Access Control Systems
Access control systems that incorporate IP and Power-Over-Ethernet (POE) components were introduced to the marketplace almost two years ago. The evolution of access control systems to structured cabling, IP protocols and POE was inevitable; look what happen to telephone and video surveillance systems. The transformation leverages the existing IT infrastructure, eliminates the need for local power, consolidates and saves labor costs for cable installation, reduces the time to install system devices, is more scalable and provides a large base of management tools and support. The move is subtlety but surely changing the design and deployment of access control systems.
Power over Ethernet: How High Can You Go? The 60W Standard Is Nearly With Us.
An informative article on the progress of PoEPlus by Daniel Feldmanon Product Line Manager, Microsemi; Voting Member, IEEE802.3; PoE/PoE+ Technical Committee Chairman, Ethernet Alliance.
The Tolly Group & Sifos Technologies; PSE Testing Comparison
The increasing use of PD equipment such as VoIP and wireless access points has to assume that the selected Power Sourcing Equipment works to the 802.3af standard. Recent test by Sifos Technologies shows that you have to look deeper into a PSE rather than just the data sheet. The Tolly Group worked closely with Sifos Technologies to study two different PSE's extensively and to report on observed ranges in performance in categories such as Static Power Delivery, Transient Power Delivery, Safety, Power Management Behaviors, and Interoperability Characteristics. Approximately 50 different parameters were analyzed with many surprising results.
Application Note on Electrical Transient Immunity for Power over Ethernet
Texas Instruments have produced a white paper that is aimed to help designers prevent damage to their devices from external unwanted voltage sources. Common and differential mode examples of induced voltages are discussed as well as ESD and EFT. The abstract is printed below.
Power over Ethernet - The Reality of Designing a Powered Device
There have been many technical articles, white papers and product application notes that explain the theory on how to make a powered device. They give an overview of the IEEE 802.3af standard for Power over Ethernet and explain how to extract the power from the CAT5e cable. The following is a practical guide to help take that information and to design a PoE enabled powered device.
Sifos Technologies Finalizes 802.3at PSE Conformance Test Suite
The PSE Conformance Test Suite is a fully automated, highly adaptive group of tests designed to assess Power Sourcing Equipment (PSE) compliance to the IEEE 802.3at specification. Sifos provides diagnostic capabilities based upon the core resources of each PowerSync® Analyzer (PSA) test port coupled with the high level processing power of PSA PowerShell Tcl Automation software.
Wall Mounted PoE Computer Terminal Opens Up Many Applications
Advantech have made installing interactive touchscreen terminal easy by including a PoE interface and using very low power consumption technology with the UbiQ-480.
Sifos Technologies Introduces IEEE 802.3at LLDP Emulation & Analysis
The PowerSync Analyzer and PowerSync Programmable Load test & measurement solutions provide powerful new testing capabilities for those working with new or developmental end-span PSE’s that use Link Layer Discovery Protocol (LLDP) for “Type 2” power enabling, power negotiations, and/or power management purposes.
Industrial Temperature Range Switches From Advantech
Advantech have introduced a range of both managed and unmanaged switches for networking, IP security cameras and wireless access points applications.
The EIPE offers a simple method of connecting a PoE end-device to a non-PoE 10/100 Mbps Ethernet switch. The EIPE is compliant to the IEEE 802.3af standard and is considered a mid-span PSE in that it resides between the non-PoE switch and the PD delivering up to 15.4 watts of power at its output connector.
Embedded Computer For PoE Applications
ADI Engineering have launched a full function embedded computer, Cinnamon Bay SBC, with a PoE interface. It offers such features as an Intel Atom CPU at up to 1.6 GHz, up to 2GB RAM, tiny 88x110mm form factor, hardware offloaded HD and SD video decoding (MPEG2, MPEG4, H.264, etc.), IEEE 1588 and 802.1as hardware Ethernet packet timestamping and time synchronization, –40 to +85C extended temperature operation, 4W typical power consumption, low cost, and easy expansion. The board runs Linux and Windows XP and XP Embedded.
TIs’ High-Power PoE Controller Can Deliver Greater Than 90 Percent Efficiency
Integrated PoE Plus controller meets new standard for a wide range of powered device applications.
A new range of industrial wireless access points (bridges) has been launched that extends wireless coverage to more than 40km for long range wireless networks. The devices are therefore ideal for a diverse range of companies that are looking to extend their industrial wireless signal coverage. Korenix UK’s new JetWave 2600 series of wireless access points have integrated Intel TDMA technology, enabling the devices to communicate over distances of at least 40km with high transmission performance.
Flexible Dome Camera From IQeye
