华为公司OptiX 2500常见告警及产生原因（HUAWEI OptiX 2500 common alarms and causes） HUAWEI OptiX 2500 common alarms and causes 1 and APS_FAIL: the alarm indicates that the automatic protection switching of multiplex section has failed. Reason: multiplexed segment information is missing or inconsistent with old and new protocols 2 and APS_INDI: the alarm indicates that multiplex section protection switching has occurred. Reason: R_LOS, R_LOF, MS_AIS, B2_EXC, or B2_SD enable or send an external reversal command 3: AU_AIS: the alarm indicates that the AU pointer in the received signal is 1 This alarm indicates that the AU4 service is not available and that the system will return the HP_RDI alarm to the destination. If a subnet connection protection is configured (SNCP), a signal failure (SF) reversal occurs 4, AU_LOP: the alarm indicates that the AU pointer in the signal received by the board is lost. The business for this AU4 is unavailable. The system will return the HP_RDI alarm to the client, and if the subnet connection protection is configured (SNCP), the signal failure (SF) will occur 5: B1_EXC: the alarm indicates that the regenerative segment (B1) error in the received signal is over the limit. The signal receiving port of the regeneration section error (B1) is too large, exceeding the performance threshold, leading to the port business is not available. When the alarm is generated, the system defaults to inserting AU_AIS across the cross direction. 6, B2_EXC: alarm with that line signal in receiving the error limit (B2). Port service is not available, the default insertion AU_AIS, while the B2 error number into M1 bytes back to end, MS_REI will receive a warning 7: BD_STATUS: the alarm indicates that the single board that has created the logical board in the system is not in or offline 8: BIP_EXC: the alarm indicates that the lower order BIP2 error of the branch board is over the limit Larger lower order channel error code (BIP) will affect the channels business usage.
