7.1.3.1 Checking the communication link operationThere are several different communication links on the product. First check that allcommunication ports that are used for communication are turned on.To check that optical serial port hardware is working, check theoptical fibres for light. Do not look directly into the transmitter sincethe direct light can be harmful for the eyes. Point the fibre ortransmitter towards a surface where it is possible to observe when thelight is on. To turn on the transmitter although there is no actualcommunication, set revPolarity in Main menu/Configuration/Communication/IEC60870-5-103/General to "On".1. Check the front communication port RJ-45.1.1. Check that the uplink LED is lit with a steady green light.The uplink LED is located on the LHMI above the RJ-45 communicationport on the left. The port is used for direct electrical communication to a PCconnected via a crossed-over Ethernet cable.1.2. Check the communication status of the front port via the LHMI in Mainmenu/Monitoring/Ethernet/Front port.Check that the "LINKUP" value is 1, that is, the communication isworking. When the value is 0, there is no communication link.2. Check the communication status of the rear port X0 via the LHMI in Mainmenu/Monitoring/Ethernet/LAN1.The X0 communication port on the rear side of the IED is for electricalcommunication to a PC connected via a crossed-over Ethernet cable. Thiscommunication port is an alternative to the front communication port.• Check that the "LINKUP" value is 1, that is, the communication isworking. When the value is 0, there is no communication link.3. Check the communication status of the rear port X1 via the LHMI in Mainmenu/Monitoring/Ethernet/LAN1.The X1 communication port on the rear side of the IED is for optical Ethernet viaLC connector or electrical via RJ-45 connector of the IEC 61850-8-1 station buscommunication.• Check that the "LINKUP" value is 1, that is, the communication isworking. When the value is 0, there is no communication link.7.1.3.2 Checking the time synchronization• Select Main menu/Monitoring/IED status and check the status of the timesynchronization on Time Synch.The Time synch value is "Ready" when the synchronization is in order.Section 7 1MRS756509 ETroubleshooting84 630 seriesOperation Manual
