During project deployment, the active and standby SCCs of two OptiX OSN 6800 NEs report the HARD_ BAD alarm at the same time.
The OptiX OSN 6800 NEs on which alarms are generated are of the 5.51.04.43 version. Alarm information is as follows:
HARD_BAD CR start 2010-07-15 18:25:05 None SA NEW_BOARD board=17;para=0x16,para=0x0,para=0x4; HARD_BAD CR start 2010-07-14 23:50:07 None SA NEW_BOARD board=18;para=0x16,para=0x0,para=0x4;
1. Query parameters of the HARD_BAD alarm. The query result indicates that the simulated phase-locked loop (PLL) circuit is faulty, which may be caused by the clock.
2. Query the clock configuration. The query result indicates that the clock source that is traced is the clock at the optical port of the 5-sc2 board.
SYN-CLASS : 3 0x0005ff01 0x0005ff02 0x0000fff0
The clock source cannot be traced because the SC2 board is not connected during the project deployment.
3. Set a local clock as the source to be traced, this alarm is cleared.
The HARD_BAD alarm will be reported if the clock tracing source is incorrectly set for the OptiX OSN 6800.
1. SCC fault.
2. SCC configuration problems, which cause incorrect alarms.
