1. Preparation work before dust removal of chassis and cabinets

1. Reasonably set the dust removal cycle of the chassis and cabinets

Set a reasonable dust removal cycle based on the actual conditions of the computer room to remove dust from indoor, outdoor and indoor equipment. Take a medium-sized computer room as an example:

The computer room is cleaned once every 3 days and once every half month.
The appearance of the computer room should be cleaned once a day, and the vacuuming status should be checked regularly every week.
Clean equipment once a month.
According to actual usage, maintenance and inspection of equipment and computer room should be carried out every two years.
Extensive maintenance and inspection of the machine room and equipment every five years.
2. Before dusting the chassis and cabinet, please take anti-static measures.

When disassembling and cleaning equipment, make sure that the equipment is not damaged during the power-on process. Before cleaning, you should wear anti-static clothing and anti-static rings and other equipment.

Operation Procedure To prevent static electricity from damaging the device, even if the device supports hot swapping, perform this operation when the power is turned off and the server is properly grounded. Equipment such as monitors should be discharged first.

3. Choose the correct cleaning tools for the chassis and cabinet

Cleaning of cabinet equipment does not require the use of complicated tools. For ordinary dust removal, use a Phillips screwdriver, a slotted screwdriver, or a paint brush.

A hair dryer, anhydrous alcohol, cooling silicone oil, cotton balls, clock pliers, tweezers, and leather tigers are also necessary tools. If simple maintenance is required, you need to prepare needle-nose pliers, electrical test pens, multimeters and other equipment.

Remember not to use ordinary brushes and other brushes that are easy to remove hair, otherwise it will easily damage the machine.

2. Chassis and cabinet dust removal techniques

1. Chassis cabinet cleaning motherboard

As the basic hardware of the entire device, the motherboard is a place where dust easily accumulates.

When cleaning, all plugs should be removed first, and the removed equipment should be numbered to prevent confusion. Then remove the screws that fix the motherboard, remove the motherboard, and use a brush to brush off the parts and remove dust.

During operation, the force must be moderate to prevent touching the chip components on the surface of the motherboard or causing the components to loosen and cause soldering. , excess dust can be cleaned with absolute alcohol.

2. Chassis cabinet processing plug-in

The surface of the plug can be cleaned in the same way as the motherboard. If the plug is oxidized, wipe the gold finger carefully with rubber to clean it. After inserting the motherboard back in, fill both sides of the slot with hot melt glue to prevent dust from entering and prevent oxidation during use.

3. Chassis cabinet cleaning fan

There is often a lot of dust accumulated inside and outside the fan blades. You can put your hand on the blade and brush them off one by one. Then wipe the fan and frame clean with a damp cloth. After cleaning, add some lubricating oil to the shaft to improve its performance and reduce noise.

4. Chassis cabinet cleaning container surface

If there is dust on the surface of the chassis, wipe it with a damp cloth. Note that the wet cloth should be dried as much as possible to avoid residual water stains. Use a hair dryer to dry it after use.

5. Clean peripheral plugs/sockets

Generally, use a brush to remove the floating soil, and then clean it with a hair dryer. If there is oil, use absolute alcohol to remove the cotton ball.

6. Chassis cabinet cleaning power supply

Power supplies are very easy to accumulate dust and are seriously affected by temperature.

When disassembling the power supply, be sure to pay attention to internal safety. If you don't have certain professional knowledge, don't dismantle it privately. You can use a hair dryer to blow the dust into the air intake.
