Operation Instructions

To minimize ESD damage, observe the following precautions:

• 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.
• 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.
• Monitor the temperature and humidity in the equipment room. Be careful to use any heating system because it decreases indoor humidity and increases static electricity.
• Place components in ESD bags or boxes during transportation or storage.
• An operator must 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 cabinet.
• 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 6-2 shows conductive objects that must be removed before you touch a device.

• 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, see Figure 6-3.
• During parts replacement, keep new server components in ESD bags before installation, and place removed server components on ESD mats for temporary storage.
• Do not touch welding points, pins, or exposed circuits.
