Automatic laser shutdown on the SL64 board of the OSN 9500

2

When one end does not receive optical signals, it reports an R_LOS alarm to automatically shut down the laser, and the peer end shuts down its laser after receiving the R_LOS alarm. To ensure that light emitting can be immediately recovered after a fault is rectified, the lasers on the ports at both ends are turned on every other minute and the turn-on state of the lasers is kept for 2 seconds. If the fault persists, the lasers will be kept shutdown for 1 minute. The lasers at both ends are recovered if optical signals can be received immediately after the fault is rectified.

Reset types in the Errorlog records of the system control boards on the OSN 9500
Question: In OSN 9500 V100R001B01, the following information is displayed after the Errlog command is issued: No.71: 2006-4-17 15:45:40 BOARD=47 TYPE=0xf0000004 SOFTTYPE=2 What does TYPE mean in the command output? Answer: TYPE: reset type. The definitions are as follows: #define VOS_RST_ERASE_FPGA 0x1 /*A reset clears the FPGA and triggers switching.*/ #define VOS_RST_ERASE_STRING 0x2 /*A reset clears records and triggers switching.*/ #define VOS_RST_COLD_BOOT 0x4 /*The board is powered on and switching is triggered.*/ #define VOS_RST_DOGRESET 0x10 /*Watchdog reset*/ #define VOS_RST_RECONLY 0x100 /*Only reset information is recorded but no reset is performed.*/ #define VOS_RST_SOFTDOGRESET 0x200 /*Software watchdog reset*/ #define VOS_RST_VALID 0xf0000000 /*A reset is successful.*/ SOFTTYPE: type of the reset software. Valid values are as follows: 1: BIOS 2: NE software 3: board software
