OSN3500 SSN1PIU single board is a power interface board, mainly for OptiX OSN devices to provide power input interface.PIU single board can be plugged in the subrack of the slot 27, 28.If with the expansion subrack, the PIU single board can also be plugged in the expansion subrack of the slot 77, 78.PIU single board indicators include the single board mechanical indicators, power consumption, input voltage and fuse. Dimensions: 44.0mm (W) x 125.2mm (D) x 261.4mm (H), Weight: 1.2kg, Maximum power consumption of the PIU veneer at room temperature (25°C) is 8W. If the input power supply is standardized to -48V, the power supply voltage should be between -38.4V and -57.6V. -57.6V. If the standard voltage of the input power supply is -60V, the power supply voltage is between -48V and -72V.
Product Name: OptiX OSN 3500
OptiX OSN 3500
Fault Category
- OTHER
- POWER_ABNORMAL
Phenomenon Description
The PWRB indicator on the N1GSCC of the OptiX OSN 3500 network element main control board lights up red, and the network management reports POWER_ABNORMAL alarm. The second power supply voltage is -54V with 20% float. After reversing the two power supplies, this alarm is still reported on the network management.
Cause Analysis
After confirming the alarm, it was found that the cause of the alarm was the incorrect jumper setting of the main control board, and the jumper caps of the J17 and J16 jumpers had been removed.
The J17 and J16 jumpers of N1GSCC are used to control the input voltage used by the device.
- Remove the jumper caps: the device uses a power supply with an input voltage of -60V.
- Retaining the jumper cap: the device uses a power supply with an input voltage of -48V.
