5. MAINTENANCE

WARNING: DO NOT, UNDER ANY CIRCUMSTANCES, open and attempt to repair the 0401 Pocket Hub. 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 0401

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 0401 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 0401 Pocket

Hub, contact:

Technical Support or your local distributor.

2. SITE CONSIDERATIONS

The site for the 0401 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 0400A Ethernet Pocket Hub functions as an

Ethernet Repeater, the entire 0400A Ethernet Repeater Hub installation should comply with the IEEE Ethernet 802.3

specification.

• RJ-45 connected cables should be configured as crossover or straight through according to installation requirements.

4. OPERATION

The 0401 Pocket Hub normally requires no intervention beyond occasionally monitoring the Power and Link/Transmit LEDs.

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.

Connecting Pocket Hub to Powered PC

NOTE: The 0401 Pocket Hub is powered ON when connected, through the AUI connector, to a powered PC. After the AUI is connected to a PC, the green Power LED is illuminated.

To power the 0401 pocket hub:

1. Locate or build IEEE 802.3 compliant AUI drop cable.

2. Connect AUI drop cable male DB-15 connector to the

Pocket Hub AUI connector.

3. Connect AUI drop cable female DB-15 connector to the

AUI port on a PC .

4. Connect the PC to external AC power.

Ensuring Correct 10BaseT Configuration

The 10BaseT cable and RJ-45 jacks for Hub to Terminal connections must be configured as straight through. The 10BaseT cable and RJ-45 jacks for Hub to Hub connections must be configured as crossover.

3. INSTALLATION

The 0401 Ethernet Pocket Hub is designed to draw power from the AUI port of a PC or hub. The 0401 Pocket Hub

MUST be connected to an AUI port BEFORE the 10BaseT ports are allowed to be powered and active.

NOTE: 0401 Ethernet Pocket Hub Link Integrity cannot be disabled. All devices connected to the Pocket Hub MUST have link functions enabled.

To install the 0401 Ethernet Pocket Hub:

• Unpack the 0401 Pocket Hub.

• Connect 0401 Pocket Hub to 10BaseT Cable.

• Connect 0401 Pocket Hub to powered PC.

Direction is provided in the pages that follow.
