What will happen if you switch ON the UPS while the main power switch ...
Explanation:
When the main power switch is OFF and the UPS is switched ON, the following things happen:
1. No Power Supply to the Computer: The main power switch is responsible for providing power supply to the computer. When it is switched OFF, no power is supplied to the computer. Hence, even if the UPS is switched ON, no power will be supplied to the computer.
2. UPS is ON: When the UPS is switched ON, the battery inside the UPS will start charging. However, since there is no power supply to the computer, the UPS cannot supply power to the computer.
3. No Output: Since there is no power supply to the computer, the monitor, CPU, and other peripherals connected to the computer will not receive any power. Hence, there will be no output from the computer.
4. Risk of Damage: If the UPS is switched ON while the main power switch is OFF, it could lead to damage to the UPS, as it will try to supply power to the computer, even though there is no power supply from the main switch.
Conclusion:
Switching ON the UPS while the main power switch is OFF will not start the computer, and it could lead to damage to the UPS. Therefore, it is always recommended to switch ON the main power switch first and then turn on the UPS.
