Specifications

DIP Switch
The DIP-switches are used to configure operation mode for LLF ( Link
Loss Forwarding ) and operation modes for the UTP/Fiber ports.
DIP-switch setup is as follows:
Note: To activate DIP switch 4, DIP 3 must be enabled.
Link Loss Forwarding: The Link Loss For warding feature sends fiber
or UTP link failure information to the switches. Any failure along the
signal link is passed to and can be seen by an attached device. This
feature is used for easy network diagnosis and supports switches
utilizing Spanning Tree Protocol.
Note: Do not change the DIP-switch setting while the UTP or fiber
ports are transmitting or receiving data as data error may occur.
Refer to page 10 for application diagram.
Rear Panel
The rear panel contains a power socket. This power socket accepts
DC 9V voltage and minimum 700mA supplied current.

Troubleshooting
• Verify that you are using the right power adapter ( DC 9V, 700mA ).
Using a power adapter with DC output greater than 9V could result
in damage to the unit and/or personal injury.
• Check the configuration DIP switch. It must be set in the same
operation mode as its link partner.
• Confirm the proper UTP/Fiber cable is being used. The Single Mode
converter must use Single Mode fiber optic cable.
