Precautions for use

Before installing the module, it is necessary to confirm the power output capability and bus version of the VME chassis to ensure stable+5V and+3.3V power supply voltages, in order to avoid abnormal module operation caused by insufficient power supply;

2. When connecting fiber optic cables, it is necessary to distinguish between the transmit (TX) and receive (RX) ports to ensure that the corresponding ports at both ends of the link are correctly connected, while avoiding dust contamination on the fiber optic interface. It is recommended to use a specialized cleaning agent to clean before connection;

3. Module parameter configuration needs to be done through GE dedicated configuration software. After configuration is completed, the parameters need to be saved locally to avoid parameter loss after power failure;

4. When networking, it is necessary to select appropriate types of optical fibers (single-mode/multi-mode) and optical modules based on the number of nodes and transmission distance to ensure the quality of link transmission. At the same time, the topology structure should be reasonably planned to enhance the system redundancy capability;

During the operation of the module, it is necessary to regularly monitor the internal temperature and link error rate. When the temperature exceeds 75 ℃ or the error rate continues to rise, it is necessary to promptly investigate heat dissipation and link problems;

6. During maintenance, the power supply of the VME chassis must be cut off first. Hot plugging and unplugging modules is strictly prohibited to avoid damaging the bus interface and internal circuits of the modules.
