PowerStar™ IV
Connectors, Switches and Status Indicators
Connectors
One Left Link (host) connector and one Right Link (host) connector are
located at the front of the PowerStar™ IV. These connectors each
provide an RJ twisted pair link to AS/400™ or S/3x host signals.
Fourteen (14) terminal device connectors, labeled 0, 1, 2, 3, 4, 5, or 6,
provide RJ twisted pair connection for distributing the AS/400™ or S/3x
host signals to terminal devices such as computer terminals and printers.
The port connectors are arranged in sets of seven which are located next
to each of the link connectors.
(AT BACK) Slide-In cards (SICs), when installed, provide either twinax
host connectors or fiber TX and RX host connectors. A connector to
external power also is located at the back of the PowerStar™ IV.
Switches
The Polarity Setting Switches are used to set the polarity sense of the
active RJ pins for the Link (host) and Port (terminal device) connections.
Status Indicators (LEDs)
Line Sync and Parity Error Status Indicators (LEDs) are provided next to
each twisted pair RJ connector for monitoring data transfer.
The Power LED indicates PowerStar™ IV connection to external power.

2. SITE CONSIDERATIONS
The site for the PowerStar™ IV must provide:
•
AC power outlet for each Powerstar™ IV
•
Adequate ventilation
•
Standard environmental conditions
•
Isolation from electrical noise, including radio transmitters and
broadband amplifiers, motors, high power electrical lines, or
fluorescent light fixtures.
Additionally:
•
The twisted pair cables should not run in the same conduit
with power line cables,
•
Phone lines should be separated from data cables,
•
Flat or “silver satin” wires should not be used.
And:
•
Unshielded twisted pair, twinax, and fiber optic cable lengths
must be greater than 25 feet (7.6 meters),
•
If twisted pair cable is used, the RJ-11 or RJ-45 connector pin
settings must be configured as shown on page 8, compatible
baluns must be selected according to the chart below, and the
polarity switch must be set as shown on page 18.
