Fault 2: The serial port console has no output.
Fault Description
After the system is started, the serial console does not display any information.
Troubleshooting
Check whether serial port cables are connected correctly, whether serial port cables are disconnected, and whether the
connected serial port is identical with that configured on the hyper terminal. Check whether the configuration of the
serial port on the hyper terminal is the same as that described in
10GEM-001-FCOE Switch Configuration Guide
. If not,
modify the serial port configuration parameters. If there is still no serial port printed information, please contact
Customer Service Department for technical support.
Fault 3: The serial port console outputs illegible characters.
Fault Description
The serial port console outputs illegible characters, which are unable to identity.
Troubleshooting
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
10GEM-001-FCOE Switch Configuration Guide
.
Fault 4: 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.
