ACTIVE STAR HUB
2. Introduction
2.1 Description
The IBM®5250 Express protocol, capable of TCP/IP support, is quickly becoming
the “de facto” standard for AS/400®5250 PC emulation. With the Active Star Hub
from Black Box, you’re guaranteed an upgrade path (via firmware) to the new
protocol for far less cost than completely replacing the hub.
The Hub is a state-of-the-art dual active star that has two host-port connections
and 14 device-port connections. It was designed with protocol-transparent criteria
and is available with either RJ-11 or RJ-45 connectors. This standards-based, flexible
UTP star solution is a low-cost alternative to expensive and rigid twinaxial
daisychain cabling. Each device port is isolated, assuring that problems won’t be
transmitted throughout the entire network. Digital Phase Lock Loop and signal
conditioning, noise suppression, and proven interoperability assure reliable and
transparent connections with all models of IBM AS/400, 3X, and compatible
terminals, printers, emulation cards, and remote controllers.
2.2 Features
• Proven interoperability with 5250 compatibles.
• Standards-based 5250 “star” hub distribution allows greater flexibility for adds,
moves, and changes.
• Meets or exceeds EIA/TIA wiring recommendations.
• Advanced noise filtering and signal conditioning allows the use of lesser-grade
cabling systems.
• Polarity insensitive as long as host and device polarities are the same.
• Guaranteed firmware upgrade path to the IBM 5250 Express protocol for up
to 800% throughput enhancement.

3. Active Pair Setup
IMPORTANT!
If you haven’t already done so, please read the safety guidelines listed
on page 1.
The factory default active pair setting for the Active Star Hub is pins 4/5. The
default and other possible configurations are shown on the identification label
located on the rear panel.
Figure 3-1. Identification Label.
You can reconfigure the active pair by following this procedure:
1. Disconnect all power to the unit.
2. Remove the top cover screws located on the rear panel.
3. Gently slide the top cover back one inch.
4. Hold the top cover and tilt it up.
5. Reconfigure the jumpers (located behind the RJ connectors on the circuit
board) as required. Settings for polarity and active pair assignment are shown
in Figure 3-2. All jumper settings must be identical.

5. Installation
IMPORTANT!
If you haven’t already done so, please read the safety guidelines listed
on page 1.
1. The Active Star Hub is designed to be placed in a 19" rack. The unit should
be properly installed using all four mounting holes. Rack hardware is not
provided. (For more information on rack hardware that will work with this
unit, call Black Box Technical Support at 724-746-5500.) We recommend that
you use plastic or nylon washers under mounting screws to protect the Hub’s
finish.
2. The external power supply is mounted on the rear panel of the Active Star
Hub. Insert the AC power cord firmly into the external Power supply.
3. Insert the male end of the AC power cord into a properly wired receptacle.
All data and mode LEDs on the Active Star Hub will light for two seconds and
fade. The amber Power LED on the front panel and the green Power LED on
the top of the external power supply will light and remain on.
4. The devices attached to each star segment must have unique addresses.
Connect all the devices to the Hub’s jacks. The LEDs may momentarily blink
as cables are attached. All Device Activity LEDs should be off. If any Device
Activity LED remains on or flashes, refer to Chapter 6, Troubleshooting.
5. Connect the host to the host ports of the Active Star Hub. All Activity LEDs
will sequentially light and remain on. If a port and its devices are Express-
ready, then the Express data rate will activate and the Express mode LED will
light. If any Activity LED does not remain on or flashes, refer to Chapter 6,
Troubleshooting.
NOTE
The Express and standard modes are mutually exclusive at the port
level. The AS/400 operates a port at the standard rate whenever a
standard rate device is detected. The AS/400 operates in the Express
mode when all of the attached devices are Express capable.

6. Troubleshooting
If you have problems with your Active Star Hub, follow the suggestions described in
this chapter.
1. Collect all information relevant to this application, including:
• Product serial numbers.
• Host type and operating system software level.
• Quantity and type of peripheral devices.
• Interconnecting cable types and distances.
• Equipment environment.
• Interconnection diagram.
2. Set up the application with the Active Star Hub in one room interconnected
with UTP jumpers. Verify the application with a host port and a terminal.
3. Search through the common problems and possible causes provided below.
The Active Star Hub’s front-panel Power LED is off.
• Verify that the AC and DC connections are correct.
• Verify that the AC outlet is functioning correctly.
If the problem persists, observe the status of the external power supply’s LED
and contact Black Box Technical Support at 724-746-5500.
A device is down or unstable.
• Verify that the host’s device type matches the device.
• Verify that the host workstation controller’s capacity has not been exceeded.
• Verify that the device is properly terminated. A peripheral is terminated when
its twinaxial port has two 54.9-ohm resistors located between the “A” phase pin
and earth ground and the “B” phase pin and earth ground. Termination is
provided via a “Y” or “T” cable assembly or by a terminating balun.
• Verify that there are no polarity reversals in the cable.

ACTIVE STAR HUB
• Verify that the cable distance does not exceed the Active Star Hub’s
specification.
• Verify that the cable is data grade.
• Verify that the wiring uses natural pairs.
• Verify that the wiring avoids sources of environmental noise.
• Verify that the balun’s pinout matches the Active Star Hub’s pinout.
• Verify that the host side balun’s pinout/polarity match the device side balun’s
pinout/polarity.
Devices interfere with each other.
• Verify that the devices on star segments have unique addresses.
• Verify that all devices are properly terminated.
