1. Introduction
This 16-port Switch is a plug-and-play 10/100Mbps Fast Ethernet switching
hub. This switch can auto-sense the operation speed (10Mbps or 100Mbps) and
operation mode (full or half duplex). It is very easy to install and use.
Every network connection can use up to 200Mbps bandwidth to transfer data
because of the switch architecture of the Switch. The total bandwidth of the
Switch is 1.6Gbps. Users can use this 16-port Switch to enhance their network
performance easily. There is a clear indicator panel for Link/Act, Full-
duplex/Collision and connection speed of each port for network status monitor.

2. Where To Place the Switch
This 16-port Switch can be placed on a flat surface (your desk, shelf or table) or
mounted onto a rack.
Place the 16-port Switch at a location with these connection considerations in
mind:
lThe switch configuration does not break the rules as specified in Section 3.
lThe switch is accessible and cables can be connected easily to it.
lThe cables connected to the switch are away from sources of electrical
interference such as radio, computer monitor, and light fixtures.
lThere is sufficient space surrounding the hub to allow for proper ventilation
(the switch may not function according to specifications beyond the
temperature range of 0 to 40 degrees C).
2.1 Placing The Switch on a Desk or Shelf
1. Place the first switch on a firm flat surface where you want to install the
stack.
2. Place next switch on the first switch. Please don't put more than three this
16-port Switches in a stack to prevent shaking of the stack.
2.2 Mounting The Switch Onto a Rack
1. Use the brackets and screws supplied in the rack mounting kit.
2. Use a cross-head screwdriver to attach the brackets to the side of the switch.
3. Position the switch in the rack by lining up the holes in the brackets with the
appropriate holes on the rack, and then use the supplied screws to mount the
switch onto the standard EIA 19-inch rack.
3. Configure the Network Connection
3.1 Connecting Devices to the Switch
[ Connection Guidelines: ]
lUse Category 3 or 5 twisted-pair Ethernet cable when connecting 10BaseT
devices to the switch (cable pin assignments defined in Appendix A)
lUse Category 5 (straight-through) twisted-pair Ethernet cable when
connecting 100BaseTX devices to the switch (cable specifications are defined
in Appendix B)
lAlways limit the cable distance to 100 meters (328 ft) as defined by IEEE
specification
3.2 Connecting to Another Ethernet Switch/Hub
The Switch can be connected to existing 10 Mbps or 100 Mbps hubs/switches.
The switch to switch/hub connection guidelines are as follows:
3.2.1 MDI to MDX Connect - Use normal "Straight Through" TP Cable when
connecting the Switch MDI port to another standard port at the other
switch/hub.
3.2.2 MDX to MDX Connect - Use crossover TP cable when connecting the
Switch device port to another standard port at the other switch/hub.

3.3 Application
An Ethernet switch can be used to overcome the hub to hub connectivity
limitations as well as improve overall network performance. Switches make
intelligent decisions about where to send network traffic based on the
destination address of the packet. As a result, the switch can significantly reduce
unnecessary traffic.
The example below demonstrates the switch ability to segment the network.
The number of nodes on each segment is reduced thereby minimizing network
contention (collisions) and boosting the available bandwidth per port.

4.1 LEDs Defined
The 16-port Switch LEDs provide useful information about the switch and the
status of all individual ports.
LED STATUS CONDITION
Power ON Switch is receiving power.
Green The LED function of Port 1 ~ 16 is "Link / Act".Display
Mode** Yellow The LED function of Port 1 ~ 16 is "FDX / Col."
(Full Duplex / Collision).
ON Port has established a valid link.if in "Link /
Act" function Flashing Data packets being received or sent.
ON The connection is Full Duplex.if in "FDX /
Col." function Flashing Packet collisions occurring. A low
level of collision is a part of normal
Ethernet Operation.

5. Troubleshooting
5.1 Resolving No Link Conditions
The possible causes for a no link LED status are as follow:
lThe attached device is not powered on
lThe cable may not be the correct type or is faulty
lThe installed building premise cable is faulty
lThe switch port may be faulty
Note: Because Port 16 MDI-X port and the MDI port share the same
components, if the Port 16 MDI-X port is used, please don't use the MDI port.
Or, if the MDI port is used, please don't use the Port 16 MDI-X port.
5.2 Q&A
1. Computer A can connect to Computer B, but cannot connect to Computer C
through the 16-port Switch.
¸The network device of Computer C may fail to work. Please check the
link/act status of Computer C on the LED indicator. Try another network
device on this connection.
¸The network configuration of Computer C may be something wrong.
Please verify the network configuration on Computer C.
2. The possible causes for the 16-port Switch no work status are as follow:
¸Power cord or the internal power supply problem. Check the Power LED
indicator.
¸MDI/MDI-X port is misused. Never use MDI port and Port 16 MDI-X port
at the same time because they share the same components.
¸The cable may not be the correct type or is faulty. And the cable length
limit is 100 meters.
¸The installed building premise cable is faulty.
3. The LED display does not work correct.
