Good day!

In the case of a S7700, run the display power command to view the power supply status.

[HUAWEI] display power
PowerID  Online  Mode   State      Current(A)   Voltage(V)   RealPwr(W)
PWR1     Present AC     NotSupply  -            -            -
PWR2     Present AC     Supply     0.82         53.40        43.79
PWR3     Present AC     Supply     0.97         53.51        51.90
PWR4     Present AC     Supply     0.95         53.51        50.83

The State field indicates the power supply status. If the State displays NotSupply, the power module does not supply power. Check whether the power supply is installed properly or whether the power switch is turned on.

Besides, you can run the display power system command on S series modular switches to check the power of each card and available power of the system. Before installing a switch or expanding the system capacity, decide whether the power capacity needs to be expanded according to the power consumption of the switch.

[HUAWEI] display power system
The total power supplied   : 800.00(W)
The maximum power needed   : 797.00(W)
The remain power           : 3.00(W)
The system rated power detail information :
-------------------------------------------------
Slot      BoardName      State        Power(W)
-------------------------------------------------
2         LPU board      Lack         61.00
12        LPU board      On           64.00
14        MPU board      On           105.00
CMU1      CMU board      On           1.00
CMU2      CMU board      On           1.00
FAN1      FAN board      On           43.00
FAN2      FAN board      On           43.00
PWR1      PWR board      On           800.00

The meanings of some fields are as follows:

- The total power supplied: indicates the total power of the system.

- The maximum power needed: indicates the maximum power required by the system.

- The remaining power: indicates the available power of the system.

- Power (W): indicates the power of each card.

Hello,


As my colleague said, you can use the 'display power' command as below: 

<HUAWEI> display power
--------------------------------------------------------------------------   
 PowerID  Online  Mode   State      Current(A)   Voltage(V)   RealPwr(W)   
-------------------------------------------------------------------------- 
 PWR1     Present AC     Supply     4.77         53.45        253.80 
 PWR2     Present -      -          -            -            -   
 PWR3     Absent  -      -          -            -            -     
 PWR4     Absent  -      -          -            -            -   
 POE1     Absent  -      -          -            -            -  
 POE2     Absent  -      -          -            -            -  
 POE3     Absent  -      -          -            -            -   
 POE4     Absent  -      -          -            -            -  

Here is the description of the display power command output:
