Such a problem is related to the settings of the serial port. Check if the settings of such parameters as the baud rate
match those in

Fault 6: The newly-inserted service card module fails to be powered on.
[Fault Description]
The system is running, yet all indicators on the panel of the newly-inserted expansion module are OFF, and the port is
faulty.
[Troubleshooting]
Check whether the module is inserted correctly. If the newly-inserted module still cannot be powered on even though
the checking is ok, please contact Ruijie Customer Service Department for technical support.
Fault 7: 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]
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 wavelengths 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.
