Electrostatic Discharge
Electrostatic Discharge Prevention
In order to prevent from damaging the system, it is necessary to take necessary precautions when you install the
system or take out/put in the component. The static electricity discharged by fingers or other conductors may
damage the main board or other electrostatic sensitive equipment. The electrostatic damage will shorten the
expected service life of above-mentioned equipment. To prevent the electrostatic damage, attention shall be paid
to the following aspects:
The product shall be packed in the anti-static package to prevent from touching the product by hands directly
during the transportation and storage.
Before the electrostatic sensitive components are transported to the work place which is not affected by static
electricity, put them in their respective package for storage.
Take out the equipment from their package, and do not put it down, but install it into the server directly. If you
want to put down the equipment,put it back in the anti-static package. Do not put the equipment on the outer
cover ormetal surface of the server.
When the equipment is still in the anti-static package,the equipment shall contact the unpainted outer metal
surface of the server for 2 seconds at least. In this way, it can implement the electrostatic discharge of the
anti-static package and your body.
Minimize the movement. The movement will lead to the accumulation of static electricity around your body.
Hold the edge or frame of the equipment, and operate the equipment carefully.
Do not touch the welding point, pin or exposed circuit.
Do not put the equipment in the place where other people can touch and damage it.
When you touch the electrostatic sensitive components or devices, it is necessary to take appropriate grounding
measures.
You should take particular care when operating the equipment in cold weather. The heating system will reduce
indoor humidity and increase static electricity.
Grounding Method for Electrostatic Discharge Prevention
There are several grounding methods. You can use one or more of the following methods when youtake out/put in
or install the electrostatic sensitive components:
You can use the wrist strap, which is connected with the grounding work area or computer chassis by grounding
wire. The wrist strap shall be scalable flexibly, and the resistance of the grounding wire shall be 10 percent of 1
Mega ohms at least. To achieve the grounding purpose, the wrist strap shall be close to the skin tightly when you
put on it.
Use the heel strap, toe strap or boot strap in the vertical work area. Tie the belt on your feet when you stand on
the conductive floor or dissipative static floor mat.
Use the conductive field maintenance tool.
