PTN1900Important Alarm Types

1. BD_STATUS

The single board is not in position.

2、CFCARD_FAILED

Alarm generated by failure of operation on CF card

CF card failure; master control failure.

3、CLK_LOCK_FAIL

Clock synchronization failure. Or the upstream station has not configured the clock, which may cause fiber breakage on both sides.

4、COMMUN_FAIL

This alarm is reported when the communication between the master board and other single boards is interrupted. It is possible that the board is in the reset state.

5、CPU_BUSY

This alarm is reported when the main control board detects that the CPU occupancy rate exceeds the upper limit.

6、DCNSIZE_OVER（PTN-3900）

This alarm is reported when the master control board of a gateway network element detects that the number of non-gateway network elements in the DCN subnet exceeds the upper limit.

7、ETH_APS_SWITCH_FAIL

Indicates protection reversal failure alarm. When the request signal in the APS ( Automatic Protection Switching ) frame sent by the port is inconsistent with the bridge signal in the received APS frame and reaches 50ms, it indicates that the switching has failed and this alarm is reported. (Failure of inversion occurs when work and protection are interrupted at the same time at the tunnel level)

8、ETH_APS_TYPE_MISMATCH

ETH_APS_TYPE_MISMATCH is a protection type information inconsistency alarm. This alarm is reported when the information in the received APS frame is inconsistent with the APS protection type configured at this end.

For example, work tunnel1 and protection tunnel2 are configured as 1:1 double-ended protection, and work tunnel1 in the protection group is configured in recovery mode and protection tunnel2 is configured in non-recovery mode.

FAN_FAIL

FAN_FAIL is a fan failure alarm. This alarm is reported when the fan fails.

10、LAG_DOWN

Aggregation group unavailable alarm.

11、LASER_MOD_ERR

The alarm indicates that the pluggable optical module on the single board does not match the type of optical port.

12, LTI

The alarm indicates that the clock synchronization source is lost. This alarm is reported if all synchronization sources of the network element are lost.

13、MEM_OVER

Memory_Over is an alarm for excessive memory utilization. This alarm is reported when the board detects that the memory utilization rate exceeds the upper limit.

The single-board configuration of a large number of services, and at the same time start a large number of alarm monitoring and performance statistics tasks, resulting in high memory utilization. Generally, the device software has not been upgraded, resulting in software incompatibility with the hardware.

14. NE_COMMU_GNE_SWITCH

Indicates that the gateway of the network element has been inverted, and the alternate gateway has been inverted from the primary gateway.

15、NESOFT_MM

Alarm Indicates a master and standby software inconsistency alarm.

16、POWER_ABNORMAL

is the power failure alarm. If the power supply of the single board is abnormal, this alarm is reported.

17、S1_SYN_CHANGE

The alarm generated after the clock source is lost and the general network element is hosted.

18、SERVICE_OUTAGE

Alarms accompanying the business, no impact on the business can be ignored.

19、SWDL_BD_EXCLUDE

is a package loading and upgrading single board isolation alarm. In the process of package loading and upgrading, the single board is added to the isolation list when the single board is added to the isolation list due to the failure of upgrading because it is offline, the storage space is insufficient, or the communication with the master is not available, and so on, and the alarm is reported.

20、TEM_HA

Indicates that the laser temperature is too high. Failure of the optical module or the temperature of the working environment is too high.

21、TEMP_OVER

is the single board working temperature overrun alarm. When the system detects that the working temperature of the single board exceeds the set upper temperature limit value or is lower than the set lower temperature limit value, the alarm will be reported.

The temperature is too high or too low, such as fan failure caused by poor heat dissipation resulting in high temperature, cold winter equipment bare working temperature is too low.

22、TIME_NO_TRACE_MODE

The single-board high-precision time is in a non-tracking state. When the single-board high-precision time function is turned on, this alarm is reported when the current tracking source of the single-board is the internal source (D0).

23、TR_LOC

The line board may be faulty. The alarm indicates a cross-board clock failure alarm. This alarm is reported when the single board detects cross board clock loss, frame header loss, or cross board failure.

24、WRG_BD_TYPE

The alarm indicates that the inserted board type is wrong. This alarm occurs when the configured logical board does not match the actual physical board type of the device.
