Networking the 0400 Ethernet Pocket Hub
The 0400 Pocket Hub can function in both simple and complex
networks.
When connected to a 10Base5 backbone, the 0400 Pocket Hub
alone provides a simple, local network solution.
When linked to other Pocket Hubs and connected to a 10Base5
backbone, the 0400 Pocket Hubs function in complex Ethernet
networks.

5. MAINTENANCE
WARNING: DO NOT, UNDER ANY CIRCUMSTANCES,
open and attempt to repair the 0400 Pocket Hub or power
supply adapter unit. Failure to observe this warning could
result in personal injury or death from electrical shock.
NOTE: Failure to observe the above warning will immediately void
the warranty.
Fault Isolation
If two network devices fail to communicate through the 0400
Pocket Hub, consider the following:
• Are the LEDs described in the previous section functioning
properly?
• Do network devices have Link Integrity enabled?
• Do network devices communicate when the 0400 Pocket
Hub is not installed between them?
• Is flat or “silver satin” wire used in site internal wiring?
• Are internal wiring patch cords, punch down blocks, and
wall jacks properly pinned or configured?
• Is the AUI cable unbroken and properly connected?
• Are network interface cards properly configured?
Technical Support Contact
For assistance in fault isolation and in maintaining the 0400 Pocket
Hub, contact:
Technical Support [phone]
or your local distributor.
0400 Ethernet Pocket Hub Connectors and
Status LEDs
RJ-45 Connectors
Four (4) 10BaseT RJ-45 jack
connectors are located at
one end of the 0400 Pocket
Hub. The RJ-45 jacks
support connection to
shielded or unshielded 100
ohm twisted pair 10BaseT
cable.
AUI and Power Supply Adapter Connectors
An external power supply
adapter connector and an
AUI connector are located at
the other end of the 0400
Pocket Hub. The power
supply adapter connector
supplies external power. The
AUI connector supports
connection to 10Base5
through an AUI drop cable.
Status LEDs
Power and Link/Transmit
status LEDs are located at the
side of the 0400 Pocket Hub.
The Power LED indicates
connection to power. The
Link/ Transmit LEDs track
the four 0400 Pocket Hub
connections to 10BaseT.

4. OPERATION
The 0400 Pocket Hub normally requires no intervention beyond
occasionally monitoring the Power and Link/Transmit LEDs.
Monitoring Power LED
The green Power LED is illuminated when the Pocket Hub is
connected to power.
Monitoring Link/Transmit LEDs
Each of the green Link/Transmit LEDs , associated with one of the
eight RJ-45 ports:
•is illuminated when a device is connected to the RJ-45
port
•flashes slowly as data is transmitted
•flashes quickly if the associated RJ-45 port has been
automatically partitioned.

Link/Transmit LEDs
2. SITE CONSIDERATIONS
The site for the 0400 Ethernet Repeater Hub must provide:
•AC power outlet for each Hub
•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:
•Since the 0400 Ethernet Pocket Hub functions as an
Ethernet Repeater, the entire 0400 Ethernet Repeater Hub
installation should comply with the IEEE Ethernet 802.3
specification, including segment number.
•RJ-45 connected cables should be configured as crossover
or straight through according to installation requirements.

Model 0400 10
5Ethernet™ Pocket Hub™
Connecting Pocket Hub to Terminal Devices
Use a straight through cable to connect Pocket Hub to terminal
devices.
Connecting Power to 0400 Pocket Hub
To power ON the 0400 Pocket Hub:
1. Locate the power receptacle on the back of the 0400
Pocket Hub.
2. Connect the 0400 Pocket Hub power connector end of
the power supply adapter to the Pocket Hub.
3. Connect the external power connector end of the power
supply adapter to external AC power.
NOTE: After the power supply adapter is connected to the 0400
Pocket Hub and to external power, the green Power LED is
illuminated.
Ensuring Correct Segment Number
Ethernet 802.3 specifications define segment number, as well as cable
characteristics. (A segment is the cable connection between cable
interfaces in an Ethernet LAN. Up to one-hundred 10Base5
connections can be made in one segment.)
When connecting Pocket Hubs, the transmission path between any
two Data Terminating Equipment (DTE) terminals can consist of no
more than five segments.
To assign segment numbers to cable connections:
1. Determine the two terminals in the network which are
separated by the greatest number of segments.
2. Assign a segment path between the terminals by labeling the
cable connected to one of the terminals “segment 1”and the
segment connected to the other terminal “segment n”(n =
total number of segments ≤5).
3. To verify that no segment paths contain more than n
segments, assign segment paths and numbers to all other
terminals.
