After the system is started, the serial port console does not display any information.
[Troubleshooting]
Check whether serial port cables are connected correctly and whether the connected serial port is identical with that
configured on the super terminal. Check whether the configuration of the serial port on the super terminal is the same as
that described in
RG-S12000 Software Configuration Guide
. If not, modify the serial port configuration parameters. If there
is still no serial port printed information, please contact Ruijie Customer Service Department for technical support.
Fault 8: The serial port console outputs illegible characters.
[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-S12000 series Software Configuration Guide.
Fault 9: The newly-inserted linecard fails to be powered on.
[Fault Description]
The system is running, yet all LEDs on the panel of the newly-inserted linecards are OFF, and the port is faulty.
[Troubleshooting]
Check whether the service card module is connected correctly and whether the summary power of the newly-inserted
linecard 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 linecard still cannot be powered on,
please contact Ruijie Customer Service Department for technical support.
Fault 10: 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.
Fault 11: Some ports can supply power via PoE, while others cannot.
[Fault Description]
The ports are connected to PoE devices. There is power on some ports, but no power on others.
[Troubleshooting]
1)
Check whether the ports without power are shut down manually by the software.
2)
Check whether the power provided by PoE is sufficient. If not, power will be supplied to only ports of higher priority.
