Therefore, you need to check whether the power switch is turned on and check whether the AC power cable is connected
when the Alarm LED is red.
Fault 7: The fan tray does not work or an exception occurs to the LED.
[Symptom]
After the system starts, the fans in the fan tray do not work or the Power LED is OFF, and the Alarm LED is red.
[Solution]
Check if the connection between the fan tray and the backplane is secure and if the connector gets loose. If the
connection is secure, you need to replace the fan tray.
Fault 8: The serial port console has no output.
[Symptom]
After the system is started, the serial port console does not display any information.
[Solution]
Check whether serial port cables are connected correctly and whether the connected serial port is consistent 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-S8600 Series 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 9: The serial port console outputs illegible characters.
[Symptom]
The serial port console outputs illegible characters.
[Solution]
Such problem is related to the settings of the serial port. Check if the settings of such parameters as the baud rate are
consistent with those in
RG-S8600 Series Software Configuration Guide .
Fault 10: The link cannot be set up between optical interfaces
[Fault Description]
The system runs normally. After the optical 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 optical
interface needs to be connected to the receiving end of the other optical 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.
