Fault Description:
The serial port console outputs illegible characters.
Troubleshooting:
Such problem is related to the settings of the serial port. Check if the settings of such parameters as the baud rate match
those in
RG-N18000 series Software Configuration Guide
.
Fault 8: The newly-inserted service module fails to be powered on.
Fault Description:
The system is running, yet all LEDs on the panel of the newly-inserted service modules are OFF, and the port is faulty.
Troubleshooting:
Check whether the service module is connected correctly and whether the summary power of the newly-inserted service
module and other modules in the system exceeds the maximum power. If so, please add more power modules to provide
the enough power for the power supply. If all checkings are OK, but the newly-inserted service module still cannot be
powered on, please contact Ruijie Customer Service Department for technical support.
Fault 9: The link cannot be set up between fiber interfaces
Fault Description:
The system runs normally. After the fiber interface is inserted into the optical module and the optical fiber is properly
connected, the link cannot be set up.
Troubleshooting:
First confirm whether the interface is a copper/fiber combo interface. If yes, it should be configured in fiber mode. Then, do
as follows:
1)
Check whether the receiving and sending ends are wrongly connected. The sending end of the fiber interface needs
to be connected to the receiving end of the other fiber interface. You can check by changing the sequence in which
the two optical fibers are connected on the optical module.
2)
Check whether the optical module wavelength of the two sides are consistent. For example, an optical module of
1310nm wavelength cannot be connected to an optical module of 1550nm wavelength.
3)
Check whether the distance between the two sides exceeds the length indicated on the optical module.
4)
Check whether the rates of the two sides match and whether the optical fiber type meets requirements. In addition,
for ports supporting different rates, check whether rate modes are configured correctly.
If above mentioned methods do not take effect, please contact Ruijie Networks for technology assistance.
