OSN3500 device characteristics:
STAT lamp: indicates the current working status of the single board
1) Bright (green) The single board is working normally
2) Bright (red) The single board hardware is faulty or there is no interface board and the interface board is faulty
3) Bright for 100 milliseconds and extinguished for 100 milliseconds (red) The single board hardware does not match (for example, the business board does not match the interface board)
4) Extinguished The single board has not been powered on
PROG lamp: indicates the state of the loading program
(1) Light (green) single-board software in FLASH or FPGA memory loading normal; or single-board software initialization is normal;
(2) 100 milliseconds on 100 milliseconds off (green) is loading single-board software to FLASH or FPGA
(3) 300 milliseconds on 300 milliseconds off (green) single-board software is being initialized, is in the BIOS boot stage;
(4) Light (red) Loss of single-board software or FPGA in FLASH, unsuccessful loading, unsuccessful initialization
SRV light: abbreviation of service, business status indication, similar to our previous alarm light, but not flashing, with color to distinguish the level of the alarm.
Bright (green) The service is working normally and there is no service alarm generated
Bright (red) The service has a critical or major alarm. Or there is a LOS alarm on the line.
On (yellow) The service has secondary and remote alarms.
Out No service configured
Note that the SRV lamps of the OSN3500 SSN4GSCC, SSN1GXCSA, and excs indicate slightly different meanings.
ACT Lamp: This lamp is the service activation status indicator, and also the main/standby status and working/protection status indicator. In fact, this lamp can be understood in this way, it is used to indicate whether the current service on the board is in the active state, indicating that the service on the board is not a working service being used, and if it is, the lamp will be on; the lamp should be on for the protection board after the occurrence of the main/standby reversal, and the lamp should be on for line boards unrelated to the TPS and the main/standby after the configuration of the active service, because the service on these boards is a service that is being used by the user. Services.
Bright (green)
A) The service on the service board is active.
B) In TPS protection mode, if a reversal occurs and the protection board is working, the protection board lights this lamp; when there is no TPS reversal, the working board is in working state and the working board lights this lamp.
C) For the master/backup crossover/master board, the current master board lights the lamp, which can be used to determine the master/backup relationship.
Out The service is in inactive state or the board is a backup board, you can pull out the board.
