9.1 Preventing Electrostatic Discharge
The static electricity on fingers or other electrical conductors may damage the mainboard or
other electrostatic-sensitive devices and shorten the product life.
To minimize ESD damage, observe the following precautions:
l
Lay ESD floors or ESD cushions in the entire equipment room, and use ESD chairs. The
equipment room is equipped with ESD clapboards, ESD screens, and ESD curtains.
l
All floor-standing electric devices, metal frames, and metal chassis shells in the
equipment room must be directly grounded. All electric meters or tools on a workbench
must be connected to the common ground point of the workbench.
l
Monitor the temperature and humidity in the equipment room. The heating system
reduces indoor humidity and increases ESD.
l
Place unused products into ESD bags to prevent direct contact with humans during
transportation and storage.
l
Before products arrive at an ESD area, store them in their own packages.
l
Place the product package on a grounded surface before taking out the product.
l
Wear an ESD wrist strap when installing or removing a server component. Ensure that
the ground terminal of the ESD wrist strap is inserted into the ESD jack in the chassis.
l
During parts replacement, keep new server components in ESD bags before installation,
and place removed server components on ESD mats for temporary storage.
l
Do not touch pins, wires, or integrated circuits.
9.2 Grounding Methods to Prevent Electrostatic Discharge
Use one or more of the following grounding methods when handling or installing
electrostatic-sensitive components:
