Then, hang on the EKI-2525P to the nails on the wall. First, use the screws included in the package to combine the EKI-2525P and metal mounting kit. And then you can install the device firmly via the components, please see Figure 2.5 as below. EKI-2xxx 16.00 158.00 Figure 2.5: Combine the Metal Mounting Kit (units: mm) 13 Chapter2 2.3.2 DIN-rail Mounting You can also mount EKI-2525P 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-2525P to the DIN-rail with angle of inclination. See figure 2.6. Figure 2.6: Installation to DIN-rail Step 1 EKI-2525P User Manual.doc 14 Then, let the device down straight to slide over the rail smoothly. See Figure 2.7 Figure 2.7: Installation to DIN-rail Step 2 15 Chapter2 2.4 Network Connection The EKI-2525P has 5 x RJ-45 ports that support connection to 10 Mbps Ethernet, or 100 Mbps Fast Ethernet, and half or full duplex operation. EKI-2525P 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-2525P (MDI-X) to another hub or switch either MDI-X or uplink MDI port. The EKI-2525P 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. 2.5 Power Connection The EKI-2525P supports dual 48 VDC power inputs and power-fail relay output. PWR2 1A@12V PWR1 DC 48V V2-V2+ L^J V1-V1 + P—Fail Figure 2.8: 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). EKI-2525P User Manual.doc 16 Troubleshooting Chapter 3 Troubleshooting 1. Power Input Verify that is using the right power cord/adapter 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). 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.
