Frequently Asked Questions - EKI-2741LX-BE Advantech

How do I access the web management interface of the EKI-2741LX-BE?

By default, the switch has IP address 192.168.0.1 (subnet mask 255.255.255.0). Connect an Ethernet cable from your PC to one of the RJ45 ports, set your PC's IP to 192.168.0.x, open a browser and enter the IP address. Default login: admin / admin.

Can I use this switch with single-mode fiber optic cables?

Yes, the SFP slots accept both single-mode and multi-mode SFP modules. The EKI-2741LX-BE is designed for long-reach connections; typically used with single-mode fiber for distances up to 10 km or more depending on the SFP module.

What is the power supply requirement for the EKI-2741LX-BE?

The switch requires a 12 to 48 VDC power supply. A terminal block is provided for wiring. Power consumption is typically 6 W. Use a regulated power source to ensure stable operation.

How can I restore factory default settings?

Press and hold the reset button (located near the terminal block) for at least 5 seconds while the switch is powered on. Release when the PWR LED starts blinking. The switch will reboot with factory defaults.

Is the EKI-2741LX-BE suitable for outdoor use?

The switch has an industrial temperature range (-40 to 85°C) and a rugged metal housing, but it is not weatherproof. It should be installed in an enclosure with at least IP54 rating if used outdoors.

What is the maximum number of VLANs supported?

The switch supports up to 256 VLAN groups based on IEEE 802.1Q tagging. You can configure port-based and tagged VLANs via the web interface or CLI.

How do I update the firmware?

Download the latest firmware from Advantech's official website. Access the web interface, go to Maintenance > Firmware Upgrade, select the firmware file, and click upgrade. Do not power off during the process.

Can I mount the switch on a DIN rail?

Yes, a DIN-rail mounting kit is included. Attach the bracket to the back of the switch and snap it onto a standard 35 mm DIN rail. Alternatively, wall mounting is possible using the provided screws.

The PWR LED is not lit. What could be the problem?

Check the power supply connection and ensure the terminal block is securely fastened. Verify that the power source provides the correct voltage (12-48 VDC). If using a faulty power adapter, replace it. If the issue persists, contact technical support.

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 \~ 60°C and accepts a wide voltage range from +12 \~ 48 V DC . Besides, it also provides 3,000 V DC 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 V _DC 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 V_DC EFT protection, which secure equipment against unregulated voltage and make systems safer and more reliable. Meanwhile, 4,000 V_DC 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 °C (wide operating temperature model) or -10 \~ 60 °C (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.

Chapter 2 Installation

In this chapter, you will be given an overview of the EKI-2741F/SX/LX hardware installation procedures.

2.1 LED Indicators

There are few LEDs display the power status and network status located on the front panel of EKI-2741F/SX/LX, each of them has its own specific meaning as the table below.

Table 2.1: EKI-2741F/SX/LX LED Definition
LED	Color	Description
P1	Green	On Power input 1 is active
		Off Power input 1 is inactive
P2	Green	On Power input 2 is active
		Off Power input 2 is inactive
P-Fail	Red	On Power input 1 or 2 has failed
		Off Power input 1 and 2 are both functional, or no power input
LNK/ACT (fiber port) Green		On Connected to network
		Flashing Networking is active
		Off Not connected to network
1000M (RJ-45)	Yellow	On Link to 1000M bps network
		Off Not connected to network
LNK/ACT (RJ-45) Green		On Connected to network
		Flashing Networking is active
		Off Not connected to network

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-2741 series DIP-Switch Definition

S/W No Status Description
1	ON Enables Port/Power Alarm
	OFF Disable Port/Power Alarm
2	ON	Enables LFP
	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.

2.5 Network Connection

• Twisted-pair segment can use unshielded twisted pair (UTP) or shielded twisted pair (STP) cabling. The cable between the link partner (switch, hub, workstation, etc.) and the converter, must be less than 100 meters (328 ft.) long and comply with the IEEE 802.3ab 1000Base-T standard for Category 5e or above.
• Fiber segment using single-mode connector type must use 9/125 µm single-mode fiber cable. You can connect two devices in the distance of 10 km.
• Fiber segment using multi-mode connector type must use 50/125 or 62.5/125 um multi-mode fiber cable. You can connect two devices up to 550m distances.
• The small form-factor pluggable (SFP) is a compact optical transceiver used in optical communications for both telecommunication and data communication applications.

To connect the transceiver and LC cable, please follow the steps shown below:

First, insert the transceiver into the SFP module. Notice that the triangle mark is the bottom of the module.

Troubleshooting

Chapter 3 Troubleshooting

1. Power Input

Verify that is using the right power cord/adapter (+12\~48 V_DC ), please don't use the power adaptor with DC output voltage higher than 48V, or it will burn this converter down.

2. Cable

Select the proper UTP/Fiber cable to construct your network. The single-mode converter must use single-mode fiber cable. Please check that you are using the right cable.

3. DIP Switch

Check the configuration DIP-switch. It must be setting in the same operation mode with the link partner.

4. Diagnosing LED Indicators

The switch can be easily monitored through panel indicators, which describes common problems user may encounter and where user can find possible solutions, to assist in identifying.

If the power indicator does not light up when the power cord is plugged in, user may have a problem with power cord. Then check for loose power connections, power losses or surges at power outlet. If user still cannot resolve the problem, contact the local dealer for assistance.

If the Industrial switch LED indicators are normal and the connected cables are correct but the packets still cannot transmit, please check your system's Ethernet devices configuration or status.
