The 1u case includes an industrial control power supply, passive backplane, and fan. Industrial control power supply: It serves for N hours of continuous disconnection, so its performance is better. The main thing to pay attention to is to minimize the entry of dust to prevent dust from affecting the operation of the fan. Prevent instantaneous power failure. A momentary power failure and a sudden call will often generate an instantaneous extremely high voltage, which is likely to "burn" the computer, and voltage fluctuations (too low or too high) will also cause damage to the computer. Therefore, power should be equipped as much as possible. In addition, it should be anti-static and anti-lightning.

Passive backplane: It provides power for various boards (cards, graphics cards, sound cards, network cards, etc.), and three points should be paid attention to in its daily maintenance: you can't remove and plug the board when the backplane is powered. Do not use too much force or too much force when pulling the card. When cleaning the bottom plate with alcohol, etc., pay attention to prevent the tool from scratching the bottom plate.

Do not accumulate dust in the slot, otherwise it will cause poor contact or even short circuit. Whether the metal feet in the slot are aligned and whether they are bent or not, otherwise it will affect the operation of the board in the system, and there will be various phenomena such as no display when booting, the board cannot be found, and the crash. Fan: The fan in the industrial control box is specially designed for the industrial computer. It blows air into the chassis to reduce the temperature in the chassis. It should be noted that whether the power supply is connected to the plug, the filter outside the fan should be cleaned regularly (once a month) to prevent excessive dust from entering the case.
The board should be protected from dust, the pins should be intact, the board should not be distorted when it is inserted vertically, and the connectors on the external socket of the board should not be plugged or inserted under power.

The above is what you should pay attention to in the use of industrial computer. As long as you are diligent in practice and do the above points, you will manage your industrial computer system and keep it running stably for a long time.

2. Use environment and matters needing attention

When using an industrial computer, please note that the surrounding temperature should be between 0 degrees and 55 degrees.

When using an industrial computer, please note that the surrounding relative humidity should be between 5-95%, without condensation.

When using an industrial computer, please note that the power supply voltage should be between 200 and 240V AC.

When using an industrial computer, please try to avoid humid, extreme temperature, vibration and dusty environments.

The opening on the left side of the industrial computer and the vent on the back of the power supply are for ventilation. In order to ensure the normal and reliable operation of the industrial computer and prevent overheating, please do not block or cover these openings.

When using an industrial computer, please try to keep a distance of more than one meter from the equipment (inverter, motor, etc.) that generates strong electromagnetic interference.

After the industrial control machine is turned off, please wait at least 8 seconds before turning it on again.

In order to ensure the reliable operation of the industrial computer, we strongly recommend that you do not change the BIOS settings of the motherboard at will.

When using the I/0 interface of an industrial computer, we strongly recommend that you do not plug or unplug it under power to avoid static electricity damage. When the industrial computer encounters a power outage for non-human reasons, in order to ensure the normal and reliable operation of the industrial computer, we strongly recommend that you immediately disconnect the industrial computer from the power supply and confirm that the power grid is stable before powering on operation; if the power supply is tight and frequent power restrictions occur, We strongly recommend that you equip the industrial computer with UPS power supply of relevant specifications to ensure the stable operation of the industrial computer.
