Model 0401

Ethernet™ Pocket Hub™

4. OPERATION

The 0401 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.

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.
