    2.4.2 DIN-rail Mounting You can also mount EKI-2541M/2541S on a standard DIN-rail by below steps. The DIN-rail kit is screwed on the industrial switch when out of factory. If the DIN-rail kit is not screwed on the industrial switch, please screw the DIN-rail kit on the switch first.
  • Page 22: Network Connection

    Network Connection Twisted-pair segment can use unshielded twisted pair (UTP) or shielded twisted  pair (STP) cabling. The cable must comply with the IEEE 802.3u 100Base-TX standard for Category 5. The cable between the converter and the link partner (switch, hub, workstation, etc.) must be less than 100 meters (328 ft.) long. Fiber segment using single-mode connector type must use 9/125µm single- ...

  • Page 24: Power Input

    Power Input Verify that is using the right power cord/adapter (+12~48 V ), please don’t use the power adaptor with DC output voltage higher than 48V, or it will burn this converter down. Cable Select the proper UTP/Fiber cable to construct your network. The single-mode con- verter must use single-mode fiber cable.
