Transition Networks PowerStar V
Active Star 5250 Hub for IBM iSeries and AS/400


PowerStar V iSeries AS400
14-port Twinax-to-RJ45
Active Star Hub


The PowerStar V Active Star Hub is a cost-effective way to convert a Twinax daisy chain topology to the greater reliability and flexibility of a Category 5 or Category 6 (Cat5 or Cat6) cabling star topology.

Call us at (800)597-2525 for other Transition networks iSeries and AS/400 wiring products such as Twinax-to-fiber converters and Twinax multiplexers. 

Direct Replacement for IBM 7299 & 6299, Gemini Express, OmniTron OmniStar, Nevada Western and other brands of Active Star Hubs


  • Connects two hosts and 14 devices in a star configuration via Cat5 or Cat6 cable at a total distance of up to 1520 meters (5,000 feet) from the host.

  • Provides true start sequence regeneration and line synchronization.

  • Each port has separate transceiver circuitry and is isolated from the other ports, so disconnecting or removing one device does not affect the other devices.

  • Automatically compensates for speed differences among 5250 devices.

  • Expansion slot and Slide-In-Cards (SICs) let you extend network distances even further. An optional modular Twinax SIC extends the total distance from the controller to each workstation to 1520 meters. Or the optional Fiber Optic SIC extends that distance to 3,000 meters.
