Protecting Against Esd Damage - Avaya S8800 Manual

Replace the Avaya S8800 Server and its components
- Use only one hand when working with powered-on electrical equipment. Keep the
other hand in your pocket or behind your back. This precaution can prevent current
from passing through your body.
• Regularly inspect and maintain your electrical hand tools for safe operational condition.
Do not use worn or broken tools and testers.
• Never assume that power was disconnected from a circuit. First, verify that the unit is
turned off.
• Always look carefully for possible hazards in your work area. Examples of hazards are
moist floors, non-grounded power extension cables, and missing safety grounds.
• Do not touch live electrical circuits with the reflective surface of a plastic dental mirror.
The surface is conductive. Touching a live circuit can cause personal injury and damage
to the server.
• Use only approved tools and test equipment. Some hand tools have handles covered with
a soft material that does not insulate you when working with live electrical currents.
• Many customers place rubber floor mats that contain small conductive fibers to decrease
electrostatic discharges near the equipment. Do not use this type of mat to protect yourself
from electrical shock.
If an electrical accident occurs:
• Use caution. Do not become a victim yourself.
• Turn off power.
• Send another person to get medical aid.

Protecting against ESD damage

Any system component that contains transistors or integrated circuits is 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. The server, the part,
the work mat, and the person handling the part must all be at the same charge.
Packaging materials that contain ESD-sensitive components are usually marked with a yellow
and black warning symbol.
Caution:
You must observe proper grounding techniques to prevent the discharge of static electricity
from your body into ESD-sensitive components.
To avoid damaging ESD-sensitive components:
• Limit your movement. Movement can cause static electricity to build up around you.
• Keep the parts in protective packages until you are ready to install them into the server.
If it is necessary to set down a part, put it back into its static-protective package. Do not
place the part on the server cover or on a metal surface.
• Place parts on a grounded surface before removing them from their containers.
