Applies to

  • NS224 shelf
  • Environment: Power Distribution Units (PDUs) with different voltages (100V and 200V)

Answer

No, it is not recommended to connect NS224 to PDUs with different voltages (e.g., 100V and 200V) simultaneously, even temporarily.

Additional Information

  • The NS224 power supply units (PSUs) are designed to operate within a wide voltage range of 100V to 240V, meaning they can function with either 100V or 200V.
  • However, connecting the system to PDUs with different voltages at the same time can create risks such as potential voltage differences, ground loops, and abnormal currents.
  • To avoid these risks, it is advised to perform the power cable replacement while the system is offline.
  • Ensure the system is powered down before switching to a different voltage PDU.
