Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from damage.
1. To avoid electrical shock, always disconnect the power from your PC chassis before you
work on it. Don't touch any components on the CPU card or other cards while the PC is
on.
2. Disconnect power before making any configuration changes. The sudden rush of power
as you connect a jumper or install a card may damage sensitive electronic components.

EKI-2741F-SX-LX User Manual 2
Chapter 1 Overview
1.1 Introduction
The EKI-2741 is designed to convert Gigabit Ethernet networks to Gigabit fiber
networks by transparently converting Ethernet signals to optic signals. The advantages
of fiber optics are wide bandwidth, EMI immunity and long-distance transmission
capability. Therefore, EKI-2741 is an ideal solution for “fiber to building” applications at
central offices or local sites. EKI-2741 supports MDI/MDIX auto detection, so you don’t
need to use crossover wires. Furthermore, the EKI-2741 can work normally from -10 ~
60o C and accepts a wide voltage range from +12 ~ 48 VDC. Besides, it also provides
3,000 VDC surge (EFT) protection against over-voltage, so it is suitable for harsh
operating environments.
1.1.1 Fast Fiber Converters Module
The EKI-2741F/SX/LX provides you with one Fiber connector for your fiber optic cable
and one Ethernet RJ-45 port (Auto MDI/MDIX) for your 1000Base-TX copper cable
connection. There are two DIP-switches to set the operation mode for UTP, Fiber ports
and link loss forwarding function.
1.1.2 Dual Power Input
To reduce the risk of power failure, the EKI-2741F/SX/LX provide +12 ~ 48 VDC dual
power inputs. If there is power failure, EKI-2741F/SX/LX will automatically switch to the
secondary power input.
1.1.3 Flexible Mounting
EKI-2741F/SX/LX are extremely compact and can be mounted on a DIN-rail or a panel,
so it is suitable for any space-constrained environment.
1.1.4 Advanced Protection
The power line of EKI-2741F/SX/LX supports up to 3,000 VDC EFT protection, which
secure equipment against unregulated voltage and make systems safer and more
reliable. Meanwhile, 4,000 VDC ESD protections for Ethernet ports make EKI-
2741F/SX/LX more suitable for harsh environments.
1.1.5 Wide Operating Temperature
The operating temperature of the EKI-2741F/SX/LX is between -40 ~ 75 ℃(wide
operating temperature model) or -10 ~ 60 ℃(standard model). With such a wide range,
you can use the EKI-2741F/SX/LX in some of the harshest industrial environments that
exist.
1.1.6 Easy Troubleshooting
LED indicators make troubleshooting quick and easy. The 10/100/1000 Base-TX port
has 2 LEDs that display the link status, transmission speed and collision status. Also
the three power indicators P1, P2 and P-Fail help you diagnose immediately.

2.2 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.
Table 2.2: EKI-2741series DIP-Switch Definition
S/W No Status Description
ON Enables Port/Power Alarm
1
OFF Disable Port/Power Alarm
ON Enables LFP
2
OFF Disables LFP
Link Fault Pass-Through (DIP-Switch 2): When LFP is enabled, it allows 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 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.
