Power failure solution

Due to unstable external power supply, aging power line or lightning strike, the power supply is damaged or the fan stops and cannot work normally. Or due to the power supply, other parts in the machine are damaged, and the switch will have problems.
If the POWER indicator light on the switch panel is green, it is normal; if the indicator light is off, it means that the switch is not supplying power normally. Such problems are easy to detect, easy to solve, and the easiest to prevent.
In response to this kind of fault, the first thing to do is to do a good job of external power supply, generally by introducing independent wires to provide independent power supply, voltage regulator, to avoid instantaneous high voltage or low voltage phenomenon. If conditions permit, you can add uninterruptible power supply to ensure the normal power supply of the switch. Some uninterruptible power supplies provide voltage regulation function, while others provide voltage regulation function. Pay attention when choosing. Set up professional lightning protection measures in the computer room to avoid the damage of lightning to the switch. There are many professional companies doing lightning protection engineering now, which can be considered when implementing network wiring.
