Power supply failure will lead to huawei OSN2500 equipment of board restoration at the same time, and business interruption. The specific reason has the following kinds:
Reason 1: net yuan power consumption than net yuan threshold power consumption. If long-term network elements in the limit state power, the power of the matching network elements board will also work in high load condition for a long time, will lead to the power board failure. Browse the current alarm on huawei OSN2500 equipment U2000 system, to check the report whether NE_POWER_OVER alarm network elements.
Reason 2: Board abnormal power supply, led to business interruption, browse the current alarm on huawei OSN2500 equipment U2000 system. To checke whether network elements report the POWER_ABNORMAL alarm.
Reason 3: the power cord loose connection or poor contact, cause business interruption. Check the connection external power supply equipment, dc power distribution box and the power of board connect the power cord connector. If the power cord loose connection or poor contact, then use a screwdriver to tighten the power cord connector or replace the power cord connector.
Reason 4: huawei OSN2500 equipment external power supply interruption or abnormal power supply fluctuation, cause business interruption. Disconnect the dc power distribution box on the power switch, the multimeter NEG the power terminal of the anode in dc power distribution box (-), will be the cathode in the power terminal RTN (+). Measure the power terminal RTN (+) and NEG (-), the voltage between the shall meet the following requirements: if the input power of the standard voltage for - 48 v, the power supply voltage should be between - 41 v ~ 60 v.If the input power of standard voltage of 60 v, the power supply voltage should be between - v ~ 51-72 v.
Reason 1: net yuan power consumption than net yuan threshold power consumption. If long-term network elements in the limit state power, the power of the matching network elements board will also work in high load condition for a long time, will lead to the power board failure. Browse the current alarm on huawei OSN2500 equipment U2000 system, to check the report whether NE_POWER_OVER alarm network elements.
Reason 2: Board abnormal power supply, led to business interruption, browse the current alarm on huawei OSN2500 equipment U2000 system. To checke whether network elements report the POWER_ABNORMAL alarm.
Reason 3: the power cord loose connection or poor contact, cause business interruption. Check the connection external power supply equipment, dc power distribution box and the power of board connect the power cord connector. If the power cord loose connection or poor contact, then use a screwdriver to tighten the power cord connector or replace the power cord connector.
Reason 4: huawei OSN2500 equipment external power supply interruption or abnormal power supply fluctuation, cause business interruption. Disconnect the dc power distribution box on the power switch, the multimeter NEG the power terminal of the anode in dc power distribution box (-), will be the cathode in the power terminal RTN (+). Measure the power terminal RTN (+) and NEG (-), the voltage between the shall meet the following requirements: if the input power of the standard voltage for - 48 v, the power supply voltage should be between - 41 v ~ 60 v.If the input power of standard voltage of 60 v, the power supply voltage should be between - v ~ 51-72 v.
