Then, hang on the EKI-2525M/2526M to the nails on the wall. First, use the screws included in the package to combine the EKI-2525M/2526M and metal mounting kit. And then you can install the device firmly via the components, please see Figure 2.5 as below. Figure 2.5: Combine the Metal Mounting Kit 13 Chapter2 2.3.2 DIN-rail Mounting You can also mount EKI-2525M/2526M 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. First, hang the EKI-2525M/2526M to the DIN-rail with angle of inclination. See figure 2.6. Figure 2.6: Installation to DIN-rail Step 1 EKI-2525M & 2526M User Manual-V2.1-051507 14 Then, let the device down straight to slide over the rail smoothly. See Figure 2.7 15 Chapter2 2.4 Network Connection The EKI-2525M or EKI-2526M has the SC type fiber port in multi mode (2Km). When you connect the fiber port to another one, please follow the below figure to connect it. Wrong connection will not allow the port to work normally. SC Connector Cable Wiring (SC to SC] Tx A- A Rx Tx B- S Rx Figure 2.8: Pin Assignment of the Power Connector Attention This is a Class 1 Laser/LED product. Don’t stare into the Laser/LED Beam. The EKI-2525M and EKI-2526M both have 4 x RJ-45 ports that support connection to 10 Mbps Ethernet, or 100 Mbps Fast Ethernet, and half or full duplex operation. EKI-2525M/2526M 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-2525M/2526M (MDI-X) to another hub or switch either MDI-X or uplink MdI port. The EKI-2525M/2526M 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. EKI-2525M & 2526M User Manual-V2.1-051507 16 2.5 Power Connection The EKI-2525M/2526M supports dual +12 ~ 48 VDC power inputs and power-fail relay output. PWR2 P-Fall PWR1 V2-V2+ V1-V1+ ( +12 ~ 48 Vqc ) Figure 2.9: Pin Assignment of the Power Connector You can connect an alarm indicator, buzzer or other signaling equipment through the relay output. The relay opens if power input 1 or 2 fails ( “Open” means if you connect relay output with an LED, the light would be off). 17 Chapter2 EKI-2525M & 2526M User Manual-V2.1-G515G7 18 Troubleshooting Chapter 3 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 cable to construct user network. Please check that is using the right cable. Use Unshielded Twisted-Pair (UTP) or Shielded Twisted-Pair (STP) cable for RJ-45 connections: 100 Category 3, 4 or 5 cable for 10 Mbps connections or 100 Category 5 cable for 100 Mbps connections. Also, be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet). Otherwise, use the 50/125 ~ 62.5|am fiber cable to connect the fiber port in multi-mode. 3. 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.
