| GarrettCom Integrates Up to 8 PoE Ports in Managed Switch GarrettCom has integrated Power over Ethernet (PoE) ports into its line of Magnum 6K Series Managed Ethernet Switches to provide a clean and cost-effective solution to supporting PoE appliances such as video surveillance cameras in power utility substations and other industrial applications where security or remote access to an industrial network is required. GarrettCom's expanded Power over Ethernet offerings now include a series of PoE Port Modules, incorporating 4 to 8 PoE ports, that can be factory-configured in any 6K switch. GarrettCom is the only supplier offering a line of heavy-duty PoE Power-Sourcing switches, ranging from small 4-port switches to rugged 32-port managed switches with Gb backbones. The new PoE port modules for 6K switches come in 35 different port configurations to address a wide variety of application needs. Modules are factory-configured, and the company is offering upgrades for existing 6K switches. The Magnum 6K Series of managed Ethernet switches includes up to 32 ports of configurable Ethernet connectivity ranging from 10 Mb copper to 1 Gb fiber backbones in a single switch, as well as sophisticated managed networks software featuring security, redundancy, performance and ease-of-use. PoE combines data and power on the same copper cabling, greatly simplifying and reducing installation costs. Industrial control systems are using PoE to get Ethernet benefits such as interoperability across multiple vendors, high bandwidth, topological flexibility, and optional redundancy, in conjunction with the single-media data and power transmission formerly offered only by fieldbuses. The growing list of PoE devices available for industrial systems now includes video cameras, rugged VOIP phones, wireless access units, annunciators, data loggers, and sensors. While the industrial market has lagged behind commercial offices in the adoption of PoE technology, GarrettCom believes that the clear benefits of PoE in extending connectivity to outlying appliances will encourage increasingly rapid adoption as additional PDs become available. Ethernet is the only affordable protocol available that can support the bandwidth requirements of security systems such as video cameras and print and iris readers. PoE modules are available in two formats: Pass-Through and Power Inside. The 48VDC Power Pass-Through modules, with up to 8 PoE ports, can be configured in 6K-Series switches with 48VDC power. Magnum 6K-Series switches with AC or 125VDC power require a Power Inside power supply that can support up to 4 PoE ports. Each PoE-enabled RJ-45 port can drive 802.3af-compliant PDs as well as deliver 10/100 Mb data transmission over the same twisted-pair cable. The PoE modules have an auto-sensing algorithm that cuts off power when 802.3af-compliant devices are not attached. Proprietary PoE and non-PoE equipment are not recognized, which protects them from possible electrical damage. GarrettCom's Magnum PoE Port Modules support the Power-over-Ethernet PSE standard for over-current protection, under-current detection, and fault protection. write your comments about the article :: © 2006 Networking News :: home page |
