1. INTRODUCTION

This guide is intended for the system or network administrator responsible for installing and monitoring a TRANSITION Networks PowerStar™ III. A working knowledge of AS/400™ peripheral connections and operations, including familiarity with communications protocols used, is assumed.

The PowerStar™ III

The PowerStar™ III, available in various models (PSIII-1/7-11, PSIII-1/745, PSIII-1/7-11-T, PSIII-1/7-45-T, PSIII-2/14-11, PSIII-2/14-45, PSIII2/14-11-T, PSIII-2/14-45-T), is an active star repeater for AS/400™ and S/3x environments that can be used for converting a twinax daisy chain topology to an unshielded twisted pair star topology.

• The PowerStar III is designed to support all 5250 compliant devices operating at approximately 1Mbps.

• Host controller link can be connected either through a twisted pair connector at the front of the PowerStar™ III or, if the optional twinax connector is installed, through the twinax connector at the back of the PowerStar™ III.

• Twisted pair port connections are identified, by PowerStar™ III model number, as either RJ-11 or RJ-45 connectors.

• Separate transceiver circuitry isolates each port.

• The following pin configurations are selectable:

RJ-11 pins 3 & 4 or 2 & 5 optionally active

(factory default: pins 3 & 4 active)

RJ-45 pins 1 & 2, 3 & 6, or 4 & 5 optionally active;

(factory default: pins 4 & 5 active).
