Problem with switch power supply

Some external factors can cause the switch to not work properly, such as external power supply instability, power line problems and so on. It will also cause damage to the internal parts of the switch due to power problems. If the power led on the switch is green, everything is OK and if the LEDs are off, the switch is not powered properly.

In order to avoid the switch power problem, first of all to ensure the power supply, it is best to use independent power line to provide independent supply, this problem will not occur. If the conditions allow, you can also add UPS (uninterruptible power supply) to ensure the power of the switch, some UPS provide stability, and others do not, so in the choice of time to pay attention.
