UNICOM Electric Unicom Velocity 10/100/1000Base-T 1000Base-SX/LX Gigabit Ethernet Converter GEP-5400TF-C - Manual (Page 6)

DIP Switch Description
The DIP-switch is used to configure operation mode for LLF (Link
Lost For warding) and operation mode for Copper/Fiber por t. The
default value of Dipswitch is OFF.
10/100/1000Base-T to 1000Base-FX converter module
Link Lost Forwarding: When LLF is enabled, it will allow copper por t
link failure to be repor ted to the Fiber side and will also allow Fiber
link failure to be repor ted to the copper side. Therefore, a link loss
for ward feature is provided on both copper and Fiber sides.
Pure Converter mode: When Pure Conver ter mode is enabled (ON),
the switch operates with the minimum latency. The transmission flow
does not wait until an entire frame is ready but instead for wards the
received data immediately after being received. The TP should be
forced at 1000M in this application.
When the DIP-Switch is in Switch Conver ter mode (OFF), the
conver ter function is the same as a Switch Hub.
[Note]
1) Do not change the DIP-switch setting when the copper or fiber por t is
transmitting or receiving data. It may cause data error.
2) Power of f, then power on when changing the DIP-switch setting.
LED Indicators
There are six diagnostic LEDs located on the front panel of these
conver ters. The LEDs provide real-time information on system status.
The indicators include SPD, LK/ACT, FDX, Fiber LK/ACT, FDX/COL and
PWR. The following table provides describes these LEDs:
