DIP-Switch
The DIP-Switch is used to configure operation mode for LLF (Link Lose
Forwarding)/LFP (Link Fault Pass-Through), and operation mode for UTP/Fiber port.
The default value of DIP-switch is OFF.
S/W No Status Description
ON Enables Port/Power Alarm
1 OFF Disable Port/Power Alarm
ON Enables LLF/LFP
2 OFF Disables LLF/LFP
ON 100Base-FX Half-mode
3 OFF 100Base-FX Full-mode
ON Media mode (100TX to 100FX)
4 OFF Switching mode
LLF/LFP (DIP-Switch 2): Enabling LLF/LFP allows UTP/STP link failures to be
reported to the fiber side and also allows Fiber link failures to be reported to the
UTP/STP side. Therefore, a LLF/LFP feature is provided in both UTP/STP and Fiber
side.
Media mode (DIP-Switch 4): When media mode is enabled (ON), it operates with the
minimum latency. The transmission flow does not wait until entire frame is ready, but
instead it forwards the received data immediately after the data being received. And
TP port should be forced at 100M in this application. When DIP-Switch is set in
switching mode (OFF), the function is the same as a Switch/Hub.
Note Please don’t change the DIP-switch setting when UTP/STP or
fiber port is transmitting or receiving data. It may cause some
data error. Besides, if you change the DIP-switch setting, please
power off the switch and power on again to make the setting
effective.
