ibmlogo.gif (4062 bytes)

Intelligent 5250 Active Star Hubs
for IBM i5, iSeries AS/400 and S/3X
For CAT5 / CAT6 Cable Installations

Overview

  • Proven interoperability with 5250 compatibles

  • Standards-based 5250 “Star” hub distribution allows greater flexibility for adds, moves, and changes

  • High reliability digital design

  • Uses LAN cabling system - simple migration

  • Advanced noise filtering and signal conditioning allows the use of poorer grade cabling systems

  • Automatic data rate detection

  • Polarity insensitive as long as host and device polarities are the same.

  • Protocol transparent design ensures future 5250 compatibility

  • Meets or exceeds EIA/TIA wiring recommendations

  • Direct Replacement for IBM 6299, Gemini Express, OmniTron OmniStar, Transition Networks PowerStar and other brands of Active Star Hubs

The IBM 7299 Star Hub transparently supports ALL features and performance gains available on the newer IBM AS/400e Advanced Series Controllers and 5250 Emulation adapters, such as TCP/IP over 5250.

The IBM 7299 Hub has 2 Host Ports supporting 14 Device Ports available with either R-J11 or RJ-45 connectors. Other features include Advanced Noise Filtering, LED Port Diagnostics, Configurable UTP Pin Assignments, and a Field Replaceable wide-ranging Power Supply.

Sample Application

The following diagram illustrates a typical application of an IBM 7299 Active Star Hub.:

The iSeries AS/400 is connected directly to the Active Star Hub with a Twinax-to-RJ45 Balun.  The Balun is connected to the Twinax Host Port on the iSeries AS/400 and an RJ45 CAT5 or CAT6 Cable is connected to the RJ45 Host Port on the Active Star Hub. A Balun is connected to the Twinax connection on the Twinax Display Station or Twinax Printer and it gets connected to one of the RJ45 Device Ports on the Active Star Hub with an RJ45 CAT5 or CAT6 Cable.  The total length of the RJ45 CAT5 or CAT6 cable from the Active Star Hub to either the AS/400 or the Twinax Device can be up to 2000 feet.  A Twinax signal over a CAT5 or CAT6 cable IS NOT limited to the 300 feet limitation of an Ethernet TCP/IP signal.
