Hi friend,
The power consumption of a board is calculated based on the following conditions:
Operating voltage: -53.5 V DC.
Ambient temperature: 25°C.
Maximum power consumption: All ports fully carry loads.
You can query the power based on the whole frame, or a specified board, or a specified EMU. The command you used gave you the maximum consumption of the entire frame.
you can use this command to query the consumption of a specific slot, for example:
To query the power of the board located in 0/3, do as follows:
huawei#display power 0/3
I hope it helpful!
