12.1 Operation Instructions
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 components in ESD bags or boxes during transportation or storage.
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 Before touching a device, ensure that you are wearing ESD clothing and ESD gloves (or
wrist strap), and remove any conductive objects (such as watches and jewelry). Figure
12-1 shows conductive objects that must be removed before you touch a device.

l Both ends of an ESD wrist strap must be in good contact. One end contacts your bare
skin, and the other is securely inserted into the ESD jack in the chassis. For details about
how to wear an ESD wrist strap, see 12.2 ESD Wrist Strap.
