We are in the process of Installing HUA-NE40E-X16A with AC Input Voltage as power source : - 

As per technical specifications :-

Full Configuration : [400G bundle] HVDC&AC:350.7 kg (773.29 lb)

Typical power consumption : 9040 W (fully configured with LPUF-480s)

Redundant Power Supply : [400G bundle] HVDC&AC: 5+5 ( 5*Feed A + 5*Feed B )

Since the total power consumption is 9040W,then we need to provide below power from AC Distribution panel ( Each Phase 220V) :-

No Of Feeds : 5*Feed A + 5*Feed B ( As per Huawei Requirements ) 

Power = Voltage * Current 

Current = Power/Voltage 

              = 9040/220 = 41.09 A 

Hence total ampere with full load configuration is : 41.09A. 

Hence we decided to provide 5*AC Power Feed with 16A breakers from Source A & 5*AC Power Feed with 16A Breakers each. 

In this case, each breaker will share 8.21A from Power Source A ( Assuming no load from Power Source B & it is standby ) 

My question is, why Huawei NE40X16A requires 5*Input VOlatges from AC/DC source.Why not there 2*Input Voltages from AC/DC distribution panel with 63A breaker

full load configurations. Because, we have shortage of no.of breakers in AC/DC distribution panel

If the design of NE40X16A requires 5*Input Voltages, then can we provide 5*Input Voltages as below :-

  1. 2*63A Input Voltage from AC/DC distribution panel to Sub Distribution Panel (Let us say Power Entry Module). 
  2. Sub Distribution Panel (PEMs) will have multiple Breakers ( 5*16A Breaker to Power Feed A * 5*16A Breaker to Power Feed B )

Is above power distribution is good to go? 

Note : For Optix OSN 8800 we provide 2xInput Voltages with 63A breaker from DC Source .

suggest you check our producertion about the power input specification.

and our Front-end circuit breaker/fuse is 63 A to 100 A.

-48 V DC power supply system supports N+1 (1 indicates the number of backup modules) PMs power module backup. The AC, 240 V HVDC, and 380 V HVDC power supply systems supports N+N (N indicates the number of working modules)PMs power module backup. The power supply system supports the backup of power supply areas A and B on the user side, ensuring that the entire system can work properly if any power supply area fails.
