PIU boards that do not support subrack power consumption queries on the U2000

All types of PIU boards support subrack power consumption queries on the U2000. The query process varies depending on types of PIU boards.
1. The TN16PIU board provides the smart meter function to measure subrack power consumption on a real-time basis.
2. For other types of PIU boards, the system control board calculates the subrack power consumption based on the power consumption data of each board in the subrack. The power consumption data, including room-temperature typical power consumption and high-temperature maximum power consumption, is measured on a non-real time basis and recorded in the system control board.
