FCC WARNING
This equipment has been tested and found to comply with the limits for a
Class B Digital device, pursuant to part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference
in a residential installation. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
Reorient or relocate the receiving antenna
Increase the separation between the equipment and receiver
Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected
Consult the dealer or an experienced radio/TV technician for help
You are cautioned that changes or modifications not expressly approved by
the party responsible for compliance could void your authority to operate
the equipment.
This device complies with part 15 of the FCC Rules. Operation is subject

Introduction
Congratulations on purchasing our high-performance 10Mbps Ethernet Hub.
Featuring ease of installation, this hub helps hook your PCs together at a
minute, communicating instantly over the net to share resources and printers.
With sixteen UTP ports and one BNC port located at the rear panel, this
device allows you to network up to at least seventeen workstations in a
standalone configuration. An uplink function is designed for connection to
another hub to extend your segment, rather than a normal port for a
workstation. For more details about Uplink function, refer to the following
section.
Running at 10Mbps with great stability, this hub complies with IEEE802.3
standard.

Left side Panel
1. Power Indicator
This LED indicator is on when the hub is powered up.
2. Collision Indicator
This LED indicator blinks when the hub detects a collision on the
network.
3. Link/Activity Indicator
These LEDs indicate the state of the data link. When the connection is
okay, these LEDs remain on. Blinking indicates data is being received
on the segment.
4. RJ-45 Ports
The hub is equipped with 16 RJ-45 ports for making 10BASE-T
hub-to-workstation connections.
5. BNC Port
Provide one BNC port for thin Ethernet (10Base2).
6. Slide switch
Port 1 is designed to provide normal or uplink function through the use
of a slide switch.
7. DC Adapter Port
Insert the power jack into this port.

Installation
1. Operating Environment
This hub must be installed and operated within limits of specified operating
temperature and humidity. Do not place objects on top of the unit or obstruct
any vents at the sides of the hub. Do not position the hub near any heating
source such as heaters, radiators, or direct exposure to sun. Prevent entering
of water and moisture into the unit. If necessary, use dehumidifier to reduce
humidity.
2. Connecting to network devices
Connect one end of the network cable to any of the RJ-45 or BNC connectors
on the rear panel, and connect the other end of the network cable to the
network device with RJ-45 or BNC connector and the maximum length
between the hub and any network devices UTP is 100 meters (300ft) and
BNC is 200 meters (650ft). Once the network cable is connected on both ends
and the attached network devices are powered on, the Link Status LED
should be lit.
3. Uplink to Another Hub
The Uplink function is designed to extend your segment by connecting to
another hub (see the figure below). Note that the Ethernet Hub’s port 1 can be
switched to an uplink function by switching the sliding switch. There are two
ways for you to connect to another hub:
1) Switch the sliding switch to the uplink mode to convert port 1 to an
uplink and use a straight-through twisted-pair cable to connect port 1 to
another hub.
2) If you use a crossover cable to connect the two Hubs, then you can use
any port on the Ethernet Hub to connect to any normal port on the other
Hub. Please note: the uplink port must be in normal mode for the method
to work.

4. Connecting the power
Plug the power cable into the hub, and connect it to an electrical outlet.
Trouble-shooting
1. Power LED is not lit
Check if the power adapter is properly connected to the power outlet.
Make sure the DC power jack is firmly plugged into the power socket of
the hub.
2. Link Status LED is not lit
Check the power switch of the network devices attached to the hub; make
sure they are turned ON.
Check the network cables; make sure they are properly connected to the
hub and the network devices.
Check the network cables; make sure the cables comply with EIA/TIA
568 specification. Use straight-through Category 3 or higher cables for
10Mbps connection.
3. Link Status LED is not lit when it is uplinked to another hub
Check the network cable, and make sure it is properly connected to both
hubs. One end of the cable should be connected to uplink port while the
other end of the cable should connect to a regular port. Do not connect
- 6 -
the cable to both uplink ports.
Check the network cable, and make sure the cable complies with EIA/TIA
568 specification. Use Category 3 or higher cables for 10Mbps hub
connection.
4. Collision LED flashes constantly
Remove all the network cables; connect the cables back one by one to
isolate the source of the collision.
Check the network cable, inferior cable quality will result in excessive
collision and error packets.
[!] Contact your dealer if problem persists.
