Ethernet™ Pocket Hub™
4. OPERATION
The 0402 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 0402 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, including segment number.
•
RJ-45 connected cables should be configured as crossover or
straight through according to installation requirements.
