PowerStar™ III

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-1/7-
45, PSIII-1/7-11-T, PSIII-1/7-45-T, PSIII-2/14-11, PSIII-2/14-45, PSIII-
2/14-11-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).
