CPRI link abnormal Optical fiber No.2: No ray.1. Check whether the optical fiber is inserted into the correct

optical port.2. Check whether the optical fiber connectors are clean.3. Check whether the rate of the optical module matches that

of the optical fiber.4. Check whether the running software version of the RRU is

correct.5. Reset the faulty board.

6. Replace the faulty board.7. Replace the optical fiber, and check whether the alarm isresolved.

VSWR of the antenna feeder abnormal1. Check whether the RRU, the antenna and thefeeder are connected correctly.

2. Check whether the connectors are screwed tightly.

3. Confirm the fault position by crossing-checking. Ifthe fault position is the RRU, replace the RRU,

or else go to the next step.

4. Check the VSWR of the antenna, the combiner andthe feeder stage by stage to confirm the faulty

component, replace or maintain the component.
