The OSN1500SSQ2CXL1single board is available in several functional versions, and the functions provided by different functional versions vary.It provides signal processing, service scheduling, clock input/output, and communication control in the OptiX OSN system.The single board supports SDH signal processing, communication control, service scheduling, clock input and output, and other functions and features.The single board consists of a synchronous timing module, an optoelectronic conversion module, a MUX/DEMUX module, an SDH overhead processing module, a communication and control module, a cross-connect module, and a power supply module, etc.The panel of the Q2CXL1 single board is equipped with a single board indicator, an interface, a function push-button switch, a bar code, and a laser safety level label. the panel of the Q3CXL1 single board is equipped with a single board indicator, an interface, a bar code, function pushbutton switches, and laser safety level labels.The veneer boards need to be inserted in the corresponding slots of the subracks according to the requirements, otherwise the veneer boards will not work properly.
The OptiX OSN1500 standby SSQ2CXL veneer board fails resulting in the inability to perform a master-standby backup. troubleshooting by soft resetting the failed veneer board.

Failure Category
- Other
- COMMUN_FAIL
- SYNC_FAIL
Phenomenon Description
The standby CXL board of OSN 1500 network element reports SYNC_FAIL alarm, the first parameter of the alarm is 0x21, and the service is not affected, and the standby CXL board reports COMMUN_FAIL alarm at the same time.
Cause Analysis
Possible reasons are:
- The veneer versions are mismatched.
- Veneer false alarm.
- The veneer is damaged and the Ethernet communication is interrupted causing the communication between the master and the backup CXL veneer to be blocked, resulting in the failure of the backup of the master and the backup CXL veneer.
Steps
- Check the host version of the site is 5.36.13.47, and all the single boards are compatible with the host, and exclude the reason that the single boards are not compatible with the version.
- Check the board versions of slot 5, slot 81 and slot 83 through the network management, and the version information cannot be queried, which means that the alarm is not caused by false alarms.
- Since the standby CXL reports COMMUN_FAIL alarm, which indicates that the Ethernet communication is interrupted, it is impossible to query the single board version of the standby CXL. At the same time, because the Ethernet communication is interrupted, the master and backup CXL boards cannot communicate with each other, so the backup CXL board reports the SYNC_FAIL alarm, and the batch backup between the master and backup CXL boards fails.
- Perform a soft reset on the slot 83 board bit master of the network element, and after the veneer operates normally, the failure disappears.
