4.4 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.
User can setup VLAN of the 16-port Switch for network management. User can also
setup Trunking of the 16-port Switch for faster trunk connection between switches.
Please refer to Section 3.1 for the configuration of the 16-port Switch.

6. Troubleshooting
6.1 Resolving No Link Conditions
The possible causes for a no link LED status are as follow:
◙ The attached device is not powered on
◙ The cable may not be the correct type or is faulty
◙ The installed building premise cable is faulty
◙ The 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.
6.2 Q&A
1. Computer A can connect to Computer B, but cannot connect to Computer C
through the 16-port Switch.
◘ Computer A and Computer C may be in different VLAN groups. Please check
the VLAN setup from the Console port.
◘ 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 trunk connection function fails to work.
◘ Please check the trunking cables are connected on trunking ports. (Please refer to
Section 4.2 for trunking connection).
◘ The connection ports on another switch must be trunking ports. Please check if
trunking switching ports are used on that switch.
◘ Because the connection ports on both sides are MDI-X ports, crossover cables
are needed for the trunk connection. Please check the cables. Cat5 is suggested.
◘ Please check the trunking setup from the Console port of the Switch to verify the
trunking function is enable. (Notes: VLAN will be disable when trunking is
enabled.)
3. The setup page os the Console port cannot appear.
◘ The COM port parameters are [Baud Rate: 9600, Data Bits: 8, Parity Bits: None,
Stop Bit: 1, Flow Control: None]. Please check the COM port property in the
Hypertrm program.
◘ Check the RJ45-DB9 adapters are connected well on the Console port of the
16-port Switch and COM port of PC.
◘ A straight-through TP cable is requested to connect the RJ45-DB9 adapters
together. Please check if the correct cable is used.
◘ Check if the COM of the PC is enabled.
4. How to configure the 16-port Switch in DOS?
◘ The “Hypertrm” is the terminal program in Win95/98/NT. Users can use any
other terminal programs in DOS/Unix/OS2… to configure the Switch. The user
interface is similar witch Hypertrm. Please refer to the user guide of that
terminal program. But the COM port parameters must be [Baud Rate: 9600,
Data Bits: 8, Parity Bits: None, Stop Bit: 1, Flow Control: None].
◘ PROCOMM and TELIX are DOS terminal program. Users can use these
programs to configure the Switch.
