Electrostatic Discharge (ESD) Damage Prevention
Anyone who handles ESD-sensitive components must be aware of the damage
that ESD can cause to electronic components and must take the proper
precautions to prevent it. Also, anyone who performs maintenance on
StorageTek equipment must complete an ESD-basics course.
CAUTION:
Potential damage to equipment: Handle ESD-sensitive components only
under ESD-protected conditions. To meet this requirement, always use
the Field Service Grounding Kit (PN 4711) and always follow these ESD
precautions and procedures when you are accessing StorageTek
equipment or handling ESD-sensitive components.
ESD Precautions
Always take the following general precautions when you work with ESD-
sensitive components:
•
Wear ESD protection whenever you remove StorageTek equipment.
•
Keep ESD-sensitive printed-circuit components in their ESD-protective
packages until you have taken all ESD-preventive steps and you are ready
to install the component.
•
Do not allow anyone to touch or handle an unprotected ESD-sensitive
component unless that person has taken all ESD precautions.
•
Reinstall all equipment covers and close all equipment doors after you have
completed the work.
•
If the grounding-kit work surface has been exposed to temperatures above
66ºC (150ºF) or below 4.5ºC (40ºF), acclimate the work surface to room
temperature before you unroll it.
•
Immediately place any component that you have removed into an ESD-
protective package.
•
Keep the grounding-kit work surface clean.
Note: To clean the work surface, use a mild detergent and water, and
•
Periodically check the electrical resistance of the ground cord and the wrist-
strap coil cord.
Note: The ground cord should measure less than 1.2 MΩ, and the coil
xvi
make sure that the surface is completely dry before you use it.
cord should measure between 0.8 and 1.2 MΩ. Repair or replace the
cords if they no longer meet these requirements.
