Question about power distribution on S series switches

36

For a fixed switch:
One or two power modules can be installed on a fixed switch. If two power modules are installed, they work in 1+1 redundancy mode.
For a modular switch:
The number of power modules installed on a modular switch depends on the maximum power actually required by the switch. Ensure that the maximum output power of power modules is larger than the maximum power actually required by the system. For example, the maximum power required by the system is 4000 W. If two 2200 W power modules are installed in the chassis, they work in 2+0 mode. If three 2200 W power modules are installed, they work in 2+1 redundancy mode. If four 2200 W power modules are installed, they work in 2+2 redundancy mode.
To query the maximum power required by the system, see Power Consumption Calc.

How to view information about power supplies on S series switches
For S series switches (except S1700), 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.
