Automatic laser shutdown on the SL64 board of the OSN 9500

39

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.

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
