INSTALLATION
Set Twisted-Pair Polarity Switches
Two (2) sets of twisted-pair polarity switches at the
PowerStar™ V front toggle the polarity of the active
RJ-45 pins for each host Link and for each set of
seven device Ports.
Set the factory default host Link switch to "A"
when connecting twinax cable to the host.
Set the host Link switch and the device Ports
switch for twisted-pair copper to "A" or to "B"
according to the pin settings and baluns
(TRANSITIION Networks or other) used at the RJ-45
port connectors:
NOTE: TRANSITION Networks
baluns listed in the table to the
left are coded as: “3-XXxx”,
where XX represents the twisted-
pair port connector (45 = RJ-45)
and xx represents the order of the
active pins (12 = 1 & 2, 21 = 2
& 1, 36 = 3 & 6, 63 = 6 & 3,
45 = 4 & 5, 54 = 5 & 4.
Optionally Install Slide-In-Card (SIC)
CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when installing slide-in cards. Failure to observe this caution
could result in circuit board failure.
To install a slide-in-card:
1.
With slide-in-card components facing up,
carefully guide slide-in-card along
card guides until connector
on slide-in-card
meets internal
PowerStar™
V edge
connector.
2.
Firmly push card into slot until
slide-in-card faceplate is flat against
PowerStar™ V frame.
3.
Rotate two slide-in-card thumbscrews into
PowerStar™ V threaded holes.
CABLE SPECIFICATIONS
Twisted Pair Cable and Connector Specifications
Category 3 OR BETTER twisted-pair copper wire is required. Either
shielded twisted-pair (STP) or unshielded twisted-pair (UTP) can be used.
DO NOT USE FLAT OR SILVER SATIN WIRE.
CATEGORY 3 CABLE
Gauge
24 to 22 AWG
Attenuation
-11.5 dB/100m @ 5-10 MHz
MINIMUM CABLE DISTANCE
7.6 meters (25 feet)
Typical Maximum Cable Distance*:

*Actual distance dependent upon physical characteristics of network installation.
RJ-45 CONNECTOR
Twisted pair connection requires one active pair configured as straight
through. Using RJ-45 connectors, the active pair can be pins 1 & 2, pins
4 & 5 or pins 3 & 6.
