10. Equipment Common troubleshooting
l Check the fiber contact with the equipment are well, Optical fiber plugs on both ends and devices to reconnect mouth in order to protect the connection is good
l Optical fiber to reconnect after warning light still have the alarm, need to run out of power meter measuring optical fiber ends the sending power and receiving power of the plate; If send power normal end plate, and the receiving optical power is unusual then is fiber; If the plate shine power is very low, and can be judged to be plate problems
l Optical plate sending power after normal use the tail fiber to this end equipment of light mouth, from the ring; If the warning light board since the ring is still warning lights, then the problem is the light board, If the warning light goes out after the ring you need to use the same method to test for the end of the light board. If the light on the end plate from the ring alarm lights are off, you can determine the fiber is problematic
l When two devices are connected via a single fiber: First ends of the optical module is different, one end is 1310nm optical module, the other end is 1550nm optical module, also the transmission distance is different for example 20KM, 40KM, 60KM etc. When the two ends communicate with each other to ensure the end of the first identified as 1310nm, and the other end is identified as 1550nm, and secondly to ensure the same distance from both ends of the work identified in order to communicate
l First check the interface contacts are good and the network cable is connected to the Ethernet interface
l Check the cable: Check the pressure line RJ-45 meets the requirements of Ethernet cable, Check the cable line sequence is correct, Connected with the PC using a crossover cable, connected to the Ethernet switch using the straight-through
l Check the configuration on both sides of the PC is correct, whether in the same network segment, Correct preparation of both ends of the IP address, Working Group, Gateway etc.
l Check the cable is connected to the telephone service interface PHONE
l Check the configuration of the device itself telephone line and the telephone service used to qualify whether the correspondence
l Equipment and cables connected to a corresponding interface connector is wired correctly
l When determining equipment business wiring accurate, please check the device Bureau remote connection is normal, central office equipment connected switches, remote devices connected telephones
l Finally, check the phone can work
