臺北2008年1月25日消息，工業(yè)網(wǎng)絡(luò)及通信解決方案的主要專業(yè)提供商Ethernet Direct公司，推出CWG-800，一款八端口web管理型吉比特PoE交換機。 當網(wǎng)絡(luò)已成為人們生活中不可缺少的部分，許多設(shè)備如：IP電話，WEB攝像機，安全攝像機，入口點，RFID閱讀器，遙控設(shè)備需要采用電力線和網(wǎng)絡(luò)線路而變得不方便。以太網(wǎng)是一個典型的調(diào)解配置設(shè)備如同PoE界面一樣將成為一種趨勢。 CWG-800結(jié)合杰出的8端口WEB管理型吉比特功率設(shè)計而成的以太網(wǎng)交換機，其所有的多功能特征都與高級以太網(wǎng)功能相似，如：DHCP、Tag-VLAN、Trunking、RSTP、IGMP，可重新定位的HTTP端口，軟件和其獨特的PoE功能適用于任何一個網(wǎng)絡(luò)設(shè)備，是提供低成本解決方案用于中小型應(yīng)用的理想選擇。 CWG-800支持5種不同的級別（0,1,2,3,4）的功率設(shè)備，基于電流保護和其獨特性，一個3位7段的LED顯示器即不損耗個別部分的功率也不會損耗整個系統(tǒng)的功率。此功能是加強系統(tǒng)性能和可靠性的關(guān)鍵性功能，因為當一個新PD被添加時，其能提供方便且安全的性能。隨后，用戶可檢查面板以決定哪類PD，是否能被負載。相反地，一旦PD被移走，面板上的功率將被提高到合適的值，信息也將會顯示在網(wǎng)頁上。 CWG-800的特征： 1. 符合IEEE802.3, IEEE802.3u, IEEE802.3z。 2. 提供8端口10/100/1000Mbps RJ45，自協(xié)商端口，每個RJ-45都有自動的MDI/MDI-X探測。 3. 支持半全雙工和線速接收和傳輸。 4. 支持半雙工的后壓流動控制和全雙功的IEEE802.3x流動控制 5. 提供MAC地址表：8K，分組緩沖：144K比特 6. 一體化地址查找引擎，支持自動地址學習 7. 支持IEEE802.1Q tag-VLAN和4K VLAN IDs 8. 支持IEEE802.1D生成樹協(xié)議，IEEE802.1w RSTP和IEEE802.1x （MD5） 9. 支持端口鏡像功能，IGMP多點傳送功能 10. 支持多點傳送、廣播風暴控制以及洪泛控制 11. 支持連接集合IEEE802.3ad和fail-over 12. 支持所有速度的巨幀（10/100/1000Mbps） 更多關(guān)于CWG-800信息，請聯(lián)系info@ethernetdirect-tw.com [font=times]original text [/font] [font=times]Ethernet Direct Introduces CWG-800, An Eight Port Gigabit PoE Switch with Stand Out Features [/font] [font=times][color=#708090]Taipei, Taiwan, 25 January, 2008 – Ethernet Direct Corporation, a professional and primary provider of industrial networking and communication solutions, introduces CWG-800, an eight port web-managed Gigabit PoE switch. As networking is a indispensable nowadays, many devices such as IP phone, web camera, security cameras, access points, RFID readers, remote-control devices need to adopt both power line and network line to become inconvenient. Ethernet is a typical deployment and devices like POE interface is becoming a trend. CWG-800 comes with a brilliant design with 8-port web-managed Gigabit Power over Ethernet switch. With all the versatile features like advanced ethernet functions such as DHCP, Tag-VLAN, Trunking, RSTP, IGMP, relocatable HTTP port, the software & its unique PoE function fits any network requirement and is ideal for small or medium size application to offer a low cost solution. CWG-800 supports 5 different classes （0,1,2,3,4） of Powered Device, over current protection and most uniquely, a 3 digit 7-segment LED display showing power consumption of either individual port or whole system. This is a critical function to greatly enhance the system performance and reliability because it provides convenience and security when a new PD is added. Then, user can check from the panel to decide whether and which class of PD can be loaded or not. Reversely, once the PD is removed, the power con dition will be increased to correct values on the panel and the information can also be shown on the web page.
