OFF Disable Power Alarm.

2 ON Enables LFP.

OFF Disables LFP.

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 failure.

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.

2.2.3.1 Installing SFP Modules

To connect the fiber transceiver and LC cable, use the following guidelines:

1. Position the SFP transceiver with the handle on top, see the following figure.
2. Locate the triangular marking in the slot and align it with the bottom of the transceiver.
3. Insert the SFP transceiver into the slot until it clicks into place.
4. Make sure the module is seated correctly before sliding the module into the slot. A click sounds when it is locked in place.

The EKI-2741LXI or EKI-2741SXI both have 1 x RJ-45 port that supports connection to 1000 Mbps Ethernet and half or full duplex operation. Both EKI-2741LXI and EKI-2741SXI can be connected to other hubs or switches through a twisted-pair straight through the cable or a crossover cable up to 100m long. The connection can be made from any TX port of the EKI-2741LXI or EKI-2741SXI (MDI-X) to another hub or switch either MDI-X or uplink MDI port.

Both EKI-2741LXI and EKI-2741SXI supports auto-crossover to make networking more easy and flexible. You can connect any RJ-45 (MDI-X) station port on the switch to any device such as a switch, bridge or router.

2.2.6 Power Connection

2.2.6.1 Overview

Warning!Power down and disconnect the power cord before servicing or wiring the serial device server.

Caution! Do not disconnect modules or cabling unless the power is first switched off.

The device only supports the voltage outlined in the type plate. Do not use any other power components except those specifically designated for the serial device server.

Caution! Disconnect the power cord before installation or cable wiring.

The EKI-2741FI/LXI/SXI supports dual 12 to 48 VDC power inputs and power-fail relay output.

The following figure illustrates a P-Fail alarm application example. The P-Fail alarm contacts are visible on the front view of the terminal block.

Troubleshooting

3.1 Troubleshooting

1. Power Input

Verify that is using the right power cord/adapter (+12\~48 VDC), 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.
