Handling Electrostatic Discharge-Sensitive Devices - Bull 1GB Intel Ethernet Switch Module Installation And User Manual

• Do not use worn or broken tools and testers.
• Never assume that power has been disconnected from a circuit. First, check that it has been
powered-off.
• Always look carefully for possible hazards in your work area. Examples of these hazards are
moist floors, nongrounded power extension cables, power surges, and missing safety grounds.
• Do not touch live electrical circuits with the reflective surface of a plastic dental inspection
mirror. The surface is conductive; such touching can cause personal injury and machine damage.
• When the power is on and power supply units, blowers and fans are removed from their normal
operating position in a machine, do not attempt to service the units. This practice ensures correct
grounding of the units.
• If an electrical accident occurs, use caution:
— Switch power off
— Send another person to get help/medical aid

Handling electrostatic discharge-sensitive devices

Any computer part containing transistors or integrated circuits (IC) should be considered sensitive to
electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between
objects. Protect against ESD damage by equalizing the charge so that the server, the part, the work
mat, and the person handling the part are all at the same charge.
✏
NOTE
Use product-specific ESD procedures when they exceed the requirements noted here.
Make sure that the ESD-protective devices you use have been certified (ISO 9000) as fully
effective.
When handling ESD-sensitive parts:
• Keep the parts in protective packages until they are inserted into the product.
• Avoid contact with other people.
• Wear a grounded wrist strap against your skin to eliminate static on your body.
• Prevent the part from touching your clothing. Most clothing is insulative and retains a charge
even when you are wearing a wrist strap.
• Use the black side of a grounded work mat to provide a static-free work surface. The mat is
especially useful when handling ESD-sensitive devices.
• Select a grounding system, such as those in the following list, to provide protection that meets
the specific service requirement.
✏
NOTE
The use of a grounding system is desirable but not required to protect against ESD damage.
Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground.
