ET2000 Replacement







   ET2000 Ethernet Terminal
For System i, i5, iSeries, AS/400 & System z, z9, zSeries and S/390


An Ethernet Terminal for Attachment to
Your IBM Power9, Power8, Power7, i5,
iSeries, AS/400 & zSeries Mainframe over TCP/IP

PLEASE NOTE: The ET2000 is no longer manufactured and is only available as a refurbished unit on an "as available" basis.  The current replacement product for the ET2000 is the AG7000 Thin Client Terminal.  If a Centronics Parallel Printer Port is needed, the IA8600 Thin Client Terminal is the alternative product.    New 122-key keyboards are available for your existing units.


The CLI ET2000 Ethernet terminal addresses today's conversion of Twinax and SNA to TCP/IP by providing an Ethernet alternative to Twinax "Dumb Terminals".

The CLI AG6601 Thin Client Terminal is the current new replacement for the ET2000.  It can be configured to act as a "Dumb Ethernet Terminal" just like the ET2000.  Both models, as well as all CLI CE.NET models, can all be configured to automatically boot up to a 5250 or 3270 sign-on screen

You can see this in the CLI YouTube Video "5250 Autostart MT2301" at the link directly below:

The AG6601 has a built-in Parallel Printer Port, like the ET2000.  The MT2301 only has USB connections.

Most IT organizations require central system administration of devices, no per seat license costs, extensive keyboard selection based on the user application and printer support. The ET2000 offers an answer to these requirements for the System i, i5, iSeries, AS/400, 3270 mainframe, RS/6000 and open systems with one model terminal.

With no boot server, the terminal just turns on and connects up to four sessions to up to four different hosts using the TN5250e, TN3270e and VT100 protocols. TN5250e protocol allows each device to maintain a static, unique device name and provides named printer support.

Featured Highlights

  • True TCP/IP Network Capabiity

  • 5250 & 3270 Terminal Emulation over Ethernet

  • Full 5250/3270 Style 122-Key 24-Command Key Keyboard (optional)

  • Printer Port Standard On All Models

The use of TCP/IP combined with the capability of flash update will allow users to maintain access to the latest features and firmware without interruption of service or additional cost.

Cost savings for System applications can be obtained by avoiding the use of PC's to provide user application support where a character based, terminal emulation sessions are required. The ET2000 provides a compatible solution without complicated configurations, seat license cost or incompatible keyboard selections at the right cost to the customer.

The perfect Ethernet replacement for Twinax or Coax "Dumb Terminals".

Simple Ethernet Connectivity

The CLI ET2000 Ethernet terminal is a true character-based "dumb" terminal that supports Ethernet connectivity for your AS/400 Network. The ET2000 features low-cost, full-function Ethernet convenience. An active printer port provides a simple connection at a cost-effective price.

Simple Interface Featuring TCP/IP and TN5250 protocols for iSeries and AS/400 connectivity, ET2000 simplifies network connectivity management. By eliminating complicated boot servers, ET2000 powers on with a sign-on screen just like a Twinax terminal. The IBM AS/400 Ethernet attachment interface provides a simple connection for your ET2000.

Hassle-Free Printing

ET2000 supports all SCS (Twinax data stream) features.  Unlike LPD, the printer connected to the ET2000 retains all the functionality as if it was connected to Twinax.


User productivity is enhanced by eliminating any learning curve and costs associated with NC or PC products. Centralized management of individual units better utilizes support and help desk assets.

Cost Savings

Eliminates 5x94 remote controllers by using a inexpensive network router. You can also eliminate your SNA WAN and use TCP/IP thereby reducing communication costs. Plus, no per seat license cost.

As with all of CLI's modular display stations, you select from a wide array of keyboard and monitor styles for individual application or user requirements.  Whether you need a compact terminal with a 9" monitor and compact keyboard, or a large screen color model, CLI can provide the proper terminal for your particular requirement.
