ESD (Electrostatic Discharge)
The static discharged by human bodies can damage static-sensitive components on the boards.
When you install and maintain equipment, observe appropriate static safety precautions to prevent personnel injuries or device damage.
Wear ESD-preventive gloves, an ESD-preventive wrist strap, or ESD-preventive clothes to avoid personal injury or damage to a device. Also use an ESD-preventative surface or mat.
For example:
When a warning indicates an electrostatic sensitive area when operating a device, you must take ESD-preventive measures.
To prevent the devices from damage, pay attention to the following during operations:
Do not touch devices with bare hands because the ESD from the human body may damage the electrostatically sensitive elements on a board.
Electronic circuits are prone to damage caused by ESD. When dealing with a disk, especially a raw disk, wear an ESD-preventive wrist strap, ESD-preventive gloves, and ESD-preventive suit. Touch only the edge of the disk.
Use appropriate ESD-preventive bags when picking up, putting down, and transporting equipment or parts.
To prevent short-circuits, do not leave or drop screws or other metallic parts in the chassis.
When you install or maintain a device, follow regulations about the use and placement of tools. You can avoid short-circuits of the devices that are caused by metallic tools.
