CLI ET4000t Thin Client


ET4000t Features and Benefits:

  • Powerful, cost-effective Mandrake Linux embedded operating system
  • RDP and Citrix ICA protocols to access Windows applications, and X Window System for graphical UNIX applications
  • Multiple terminal emulations to access midrange, mainframe, Linux, UNIX, and other legacy applications
  • Netscape Navigator browser to access Web-based applications, with Java Virtual Machine (JVM)
  • Small footprint and internal power supply to reduce clutter and ease installation and use
  • Higher-performance CPU and multiple simultaneous session support to increase speed and productivity
  • No fan or other moving parts for quiet operation and high reliability, backed by an industry-leading three-year next-day advanced replacement warranty
  • Centralized management with bundled CLI SNMP Administrator software, including remote shadowing and asset tracking
  • The ET4000t thin client, with its high quality, versatility, and flexibility, is a high-performance terminal that gives users the ability to access Windows, Internet, and legacy applications, at a lower total cost of ownership than PCs or other computing products.

Mandrake Linux, an easy-to-use and highly reliable, stable and secure operating system, drives the ET4000t client software. It has built-in support of RDP and Citrix ICA protocols, multiple terminal emulations (such as IBM 5250, 3270 and 3151, DEC VT-420, among others), and Netscape Navigator. Users can access applications running on Microsoft Windows Server 2003 and Citrix MetaFrame, as well as midrange, mainframe, Linux, UNIX, X Windows and other legacy applications, and the Web.

This provides broad application compatibility and system integration, improving user productivity. And since it uses Mandrake Linux, the ET4000t is POSIX compliant, and supports many third-party device drivers.

Higher-performance CPU, serial and parallel printer ports, 10/100 BaseT Fast Ethernet, USB and PS/2 ports, audio and an internal power supply are all standard ET4000t hardware contained in a small footprint metal enclosure. This, plus Mandrake Linux's advanced and efficient hardware detection capability, simplifies network and peripheral connection and unit deployment, reducing installation time to just minutes.

And like all CLI thin clients, the ET4000t works seamlessly with CLI's SNMP Administrator software. This powerful tool gives administrators complete centralized control of all CLI desktops, dramatically reducing support costs.
