2.5 Setting the Configuration Switches  
Open the configuration switch cover on the rear of the unit. There are  
two switch groups as illustrated below:  
Figure 2-9 Configuration Switches  
The following table specifies the definition of each switch:  
The M switch only functions for Port #9 and Port #10. Since Port #1 to  
Port #8 are fixed 10BASE-T ports, the speed of these ports is fixed at  
10Mbps. No speed selection is available. D1-D8 switches are used for  
selecting the duplex mode for each 10BASE-T port respectively.  
Port #9 and Port #10 can be configured as NWay auto-negotition ports if the M  
switch is set to OFF position. This setting applies to both ports at the same time.  
The auto-negotiation mode enables the port to negotiate a common op-  
eration mode with the device connected at the remote end of the link  
cable. The common operation mode is negotiated in the sequence as  
follows:  
9
 
When a operation mode is accepted by the remote device, the mode is used for  
the data transfer between the port and the connected device. Full-duplex opera-  
tion enables two devices to transfer data bi-directionally at the same time.  
For connecting to a hub, refer to the following table for the switch setting:  
Port

Factory Default Settings  
All switches are set to OFF position when the switch unit is shipped out  
from factory. That means Port #1 to Port #8 are at half-duplex mode and  
Port #9 and Port #10 are at auto-negotiation mode.  
Important Note:  
As long as any change on the settings of the switch groups is made, you  
must turn the power to the switch unit off and turn it on again to make  
the change take effect.

3. Making Network Connections  
3.1 Network Switched Ports  
There are ten ports on the switch for connection to ten LAN segments.  
Each segment is an independent shared network in one collision-do-  
main.  
Figure 3-1 Network Ports  
Port #1 to Port #8 are 10Mbps-based 10BASE-T switched ports and  
dedicated for connecting to eight separate 10Mbps Ethernet segments  
through individual 10BASE-T connections.  
Port #9 is a 10/100Mbps-based dual-speed switched port. It can support  
connection to either one 10Mbps Ethernet segment or one 100Mbps  
100BASE-TX fast Ethernet segment. It features the capability of auto-  
sensing the speed of the connected segment.  
Port #10 is a configurable expansion port slot. The slot can be config-  
ured with one optional port module. Once installed, the slot becomes a  
network switched port and can be used for connecting to an additional  
network segment. Two optional modules are:  
10/100BASE-TX port module - dual speed 10/100BASE-TX  
100BASE-FX port module - 100BASE-FX fiber optic

monitoring the operation of the unit as illustrated below:  
Figure 4-1 LED Indicators  
4.2 Interpretation  
One Power LED indicates the status of the power supplied to the switch.  
Each port has two LEDs to indicate the port status including cable link,  
partition state, activity, collision, and duplex mode. Every port has iden-  
tical interpretations for the LED display.  
The LED can display two different colors. Different colors present dif-  
ferent meanings as the table shown below:  
Partition : the port is in partitioned state.  
Activity : there are packets transmitted or received on the port.  
Collision : there are collisions occurred on the port.
