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 (800) 260-1312

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.
