Alarm Name

Alarm Meaning

Other Description

DBMS_PROTECT_MODE

The database is in protected mode. When there is a database corruption, the data recovered from the database may cause the host software to reset frequently, or the recovery process of the database itself may cause a reset. Once this happens, the host software cannot recover to normal state by itself. Therefore, when the host is frequently reset, this alarm is generated to prevent reset due to the confusion of database data: on the one hand, it can notify the user or the maintenance personnel of the current state; on the other hand, when the database is in the protection mode, it will not recover the data from the database, so as to make the host software recover to a stable state

WRG_BD_TYPE

Board type error. It means that the actual physical board type inserted in a slot is not consistent with the logically configured board type, of course, it is also possible that the single board software has reported the wrong board type.

POWERFAIL

This alarm is reported when the battery voltage on the master board is insufficient.

DBMS_ERROR

Database error. DBMS_ERROR is reported when an operation on the database fails at the database storage level (note: this does not mean at the application module level), or when the database module fails to validate the database.

NESTATE_INSTALL

Huawei OSN3500 network elements are in an installation state. A network element that has not been verified or has not been verified successfully since it was started is in the NESTATE_INSTALL state.

SECU_ALM

User Illegal Login Alarm. When a user fails to log in to the network element three times in a row within five minutes, the network element is in the locked state and reports this alarm.

NESF_LOST

Host software loss alarm.

ALM_APS_MANU_STOP

Multiplexed segment protocol manual stop alarm. 1) The user stops the multiplexed segment protocol using the cfg-stop-rms command; 2) The user stops the multiplexed segment protocol using the cfg-stop-lms command.

HARD_BAD

Hardware bad alarm. Alarm Parameter Meaning:

para [3] 0 to 7

[0] Hardware failure detected by software

[1] Veneer hardware in place fault

[2] Veneer plugged in fault

[3] SD539 HW fault

[4] 20M crystal failure

[5] 25M crystal failure

[6] First 38M clock fault

[7] Second 38M clock fault

para [4] 0 to 3

[0] Power module 3.3V fault on this board

[1] Network management Ethernet port fault

[2] Inter-board Ethernet port failure

[3] Inter-SCC Ethernet port failure

There are six types of hardware faults detected by software as follows, which will be used as conditions for master reversal: 3.3V voltage, 3.6V voltage, 2.5V voltage, 1.8V voltage, network management Ethernet port status and inter-board Ethernet port status.

The meaning of alarm parameters is the same for OSN3500 and 2500, but the modules responsible for detection are different, which the user may not need to understand

POWER_ABNORMAL

Power failure alarm:

Currently, the host of Huawei OSN3500 device will detect 10-channel voltages, and the 10-channel voltage detections are 3.3V for AUX board, 3.3V for backup power supply, 3.3V for the main board, 3.6V for the main board power module, 2.5V for the main board, 1.8V for the main board, 5V for the main board, 3.3V for the backup power supply after jogging (V33_BAKIN), 3.3V for the A channel-48V and B channel-48V. 48V are detected. The alarm parameters are as follows:

para [3] 0 to 7

[0] AUX3V fault

[1] 3VBAK fault

[2] V33 fault

[3] V36 fault

[4] V25 fault

[5] V18 fault

[6] V5 fault

[7] V33_BAKIN fault

para [4] 0 to 1

[0] A circuit -48V

[1] B road-48V
