1. Introduction  
The 10/100 bridging converter provides two 10/100Mbps-based  
Fast Ethernet switch ports. Port 1 features one 10/100M UTP  
connection and Port 2 features either one 10/100M UTP connection  
or one 100M fiber connection. It provides a cost-effective solution  
for bridging between 10 and 100Mbps networks, extending distance  
for 100Mbps networks, and media conversion for UTP cable and  
fiber cable. Three models are available for multimode ST fiber, mul-  
timode SC fiber, and single mode SC fiber connections respectively.  
Both switched ports feature NWay auto-negotiation capability by  
which they can negotiate the speed and duplex mode with the con-  
nected device.  
The following figure illustrates the front and rear view of the switch:

2. Installation  
Unpacking  
Check to see that you have everything before you start the installation.  
• Installation guide  
• The unit  
• One AC power adapter for the switch  
Installation  
The switch can be placed on a desktop as a stand-alone unit. It also  
can be mounted on a magnetic-sensitive metal surface with its rub-  
ber magnet stand located on the bottom of the unit.  
-4-  
 
Checking AC Power  
One AC power adapter is contained in the product package. Before  
you begin the installation, check the AC voltage of your area. The  
AC power adapter which is used to supply the DC power for the  
unit should have the AC voltage matching the commercial power  
voltage in your area.  
The specifications of the AC power adapter are:  
• AC input power: AC power voltage of your area  
• DC output power:+12 VDC 800mA min.  
• DC plug type:  
The power socket for the AC power adapter is located on the rear of  
the unit as shown below:

3. Making Network Connections  
Two Switched Ports  
Two switched ports are located on the front panel.  
Configuration Switches  
On rear panel, Port 1 and Port 2 have individual configuration switches  
as shown below:  
Port 1, Port 2 SW1 Off  
Auto-negotiation is enabled.

Important Note:  
If any change are made to the configuration switch  
settings, the power to the unit must be turned off and  
turned on again before the changes can take effect.  
The auto-negotiation mode enables the port to negotiate a common  
operation mode with the device connected at the remote end of the  
link cable. The common operation mode includes connection speed  
and duplex type. When an operation mode is accepted by the re-  
mote device, the mode is used for the data transfer between the port  
and the connected device.  
TP Ports  
In order to provide flexible connection to a remote device using a  
popular straight-through UTP cable, each port features two types  
of RJ-45 jacks.

UTP Connections  
The following figure shows a UTP connection from TP port to  
another device via a straight-through UTP cable. When TP port of  
Port 2 is used, make sure Port 2 SW4 is set to OFF position.  
Depending on the configuration switch setting, the operating modes  
used for connecting to different devices are shown as follows:

Fiber Port and Fiber Connection  
When connecting to a 100BASE-FX device using fiber cable, make  
sure Port 2 SW4 is set to ON position and TX-to-RX connection  
rule is followed.  
Since the fiber connector does not support auto-negotiation func-  
tion, it is recommended to set SW1 to ON position for the fiber  
connection. If SW1 is set to OFF, it operates on half-duplex mode.  
Fiber Cables  
The required fiber cable for the connection are:
