Power supply
To meet the power supply requirements:
Calculate the system power consumption.
Select power modules according to the system power consumption and power supply mode.
To ensure normal operation of the switch, make sure the maximum output power of the power modules is greater than the system power consumption of the switch (reserve certain power for redundancy). After determining the system power consumption and power supply mode (AC or DC power supply), you can select power modules as needed.
Verify that the power source on the installation site meets the requirements of the power modules.
Make sure the power source of the installation site is steady and can meet the requirements of the power modules, including the input method and rated input voltage.
For the power consumption and power module specifications of the switch, see "Appendix A Technical specifications."
