PSU Specifications
- The device supports AC or DC PSUs.
- The PSUs are hot-swappable and work in 2+2 redundancy mode.
- When 2000 W AC PSUs are used, 4 kW power capping is enabled by default. Customers can evaluate whether to accept 3+1 redundancy backup based on upstream power distribution capabilities. After reaching an agreement with Huawei, the customers can contact after-sales personnel to increase the power capping threshold.
- When 1800 W DC PSUs are used, only 3+1 redundancy backup is supported.
- The PSUs on the same device must be of the same model.
- The recommended current specifications of the circuit breakers connected to the device are as follows:
- AC: 32 A
- DC: 63 A
- The PSUs are protected against short circuit. Double-pole fuse is provided for the PSUs with dual input live wires.
- In an equipment room with 110 V voltage, dual live wires must be used to connect to PSUs to ensure normal power supplies to the device.
- For details about the PSU specifications, see the Computing Product Compatibility Checker.
