DIP Switch
The DIP switch is used to configure operation mode for LFP (Link Fault Pass-
Through) and operation mode for UTP/Fiber port. The default value of DIP switch is
OFF.
S/W No

Link Fault Pass-Through (DIP switch 2): When LFP is enabled, allowing UTP link
failures to be reported to the fiber side and also allows Fiber link failures to be
reported to the UTP side. Therefore, a link loss forwarding feature is provided in both
UTP and Fiber side.
Note!
When SW 2 is on, once the fiber or UTP/STP cable is disconnected, the
LNK/ACT LED off. When the cable is reconnected, the LNK/ACT LED
blinks for 2 ~ 6 seconds which means the connection recovers from fail-
ure.
Note!
Please don't change the DIP switch setting when UTP 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 converter and
power on again to make the setting effective.
2.2.3
SFP Connection
EKI-2741FI has one SFP slot for connecting to the network segment with single or
multi-mode fiber. You can choose appropriate mini-GBIC module to plug into the slot.
Make sure the module is aligned correctly and then slide the module into the SFP slot
until a click is heard. You can use proper multi-mode or single-mode fiber according
to the used SFP module. With fiber optic, it transmits speed up to 1000 Mbps and you
can prevent noise interference from the system and transmission distance up to 110
km, depending on the mini-GBIC module.
Also, if you insert the 100Mbps SFP transceiver into the SFP module even without a
fiber connection to the remote, the connection of the accompanying copper port will
link down immediately.
