- The Optix OSN3500 SSN4GSCC determines the alarm based on the single board that reports the alarm. if it is not reported by the master board. refer to Checking whether the crossover board or the service board reports the HARD_BAD alarm.
- If it is reported by the main control board, do the following judgment processing.
- Optix OSN3500 SSN4GSCC If parameter 1 = 0xFF, parameter 2 to parameter 3 = 0xFF, meaningless. At this time, it means that the alarm is reported to the main control board failure, the specific failure is determined according to parameters 4 and 5, and the site can replace the alarm reported to the main control board.
Parameter name
Parameter Meaning
Parameter 4
For the main control board, if parameter 1=0xFF, parameter 4 represents a different meaning.
For GSCC board, the meaning of parameter 4 is as follows:- bit[0]=1 indicates that the software detects the hardware set bad.
- bit[3]=1 means the internal chip is bad.
- bit[4]=1 indicates that the 20M crystal is faulty.
- bit[5]=1 indicates 25M crystal failure.
- bit[6]=1 indicates the first 38M clock failure.
- bit[7]=1 indicates a second 38M clock failure.
For SCA single board, the meaning of parameter 4 is as follows:- bit[0]=1 indicates that the software detects a bad hardware placement.
- bit[2]=1 indicates a programmable logic device failure.
- bit[3]=1 indicates a 32M clock failure.
- bit[4]=1 indicates a 33M crystal failure.
- bit[5]=1 indicates a 25M crystal failure.
- bit[6]=1 indicates the first 38M clock failure.
- bit[7]=1 indicates a second 38M clock failure.
A bit of 1 indicates that the alarm exists, and a bit of 0 indicates that the alarm does not exist. Multiple bits can be in effect at the same time.
Parameter 5
For the master board, if parameter 1 is 0xFF, parameter 5 represents a different meaning.
For GSCC single board, the meaning of parameter 5 is as follows:- bit[0]=1 indicates that the 3.3V power module of this board is faulty.
- bit[1]=1 indicates that the Ethernet port (ETH) between the master and the network management is faulty.
- bit[2]=1 indicates a failure of the Ethernet port for inter-board communication between the master and other single boards.
- bit[3]=1 indicates an internal network port failure between the master and backup master.
- bit[4]=1 indicates a 1.8432M crystal failure.
For SCA single board, the meaning of parameter 5 is as follows:- bit[0]=1 indicates a 3.3V power module failure on this board.
- bit[1]=1 indicates that the Ethernet port (ETH) between the master and the network management has failed.
- bit[2]=1 indicates a failure of the Ethernet port for inter-board communication between the master and other single boards.
- bit[3]=1 indicates an internal network port failure between the master and backup master.
- bit[4]=1 indicates a 125M clock failure.
A bit of 1 indicates that the alarm exists, and a bit of 0 indicates that the alarm does not exist. Multiple bits can be in effect at the same time.
- If parameter 1 ≠ 0xFF, parameter 2 to parameter 5 = 0xFF, meaningless. Parameter 1 indicates that a service single board or cross single board 2K/8K line failure is detected, and the specific value represents the single board board number of the 2K/8K line failure. The steps are handled as follows:
- Parameter 1 Slot business board failure, please replace this single board to solve the problem and check whether the slot is backward pin.
- Optix OSN3500 SSN4GSCC If parameter 1 = 0xFF, parameter 2 to parameter 3 = 0xFF, meaningless. At this time, it means that the alarm is reported to the main control board failure, the specific failure is determined according to parameters 4 and 5, and the site can replace the alarm reported to the main control board.
