Preventing Electrostatic Discharge
Electrostatic discharge (ESD) can damage electronic
components and equipment. ESD occurs when
electronic components are improperly handled and can
result in complete or intermittent failures. Always follow
ESD-prevention procedures when removing and
replacing components.
Use the following guidelines to prevent ESD damage:
•
Always use an ESD wrist or ankle strap and ensure that it makes
skin contact.
•
Connect the equipment end of the strap to an unpainted metal
chassis surface.
•
If no wrist strap is available, ground yourself by touching the metal
chassis.
•
When installing a component, use any available ejector levers or
captive installation screws to properly seat the bus connectors in the
backplane or card slot. These devices prevent accidental removal,
provide proper grounding for the system, and help to ensure that
bus connectors are properly seated.
•
When removing a component, use any available ejector levers or
captive installation screws to release the bus connectors from the
backplane or card slot.
•
Handle adapter cards by available handles or edges only. Avoid
touching the printed circuit boards or connectors.
•
Place a removed component board-side-up on an antistatic surface
or in an approved antistatic container.
•
If you plan to return the component to DPT, immediately place it in
a static shielding container.
•
Avoid contact between printed circuit boards and clothing. The
wrist strap only protects components from ESD voltages on the
body; ESD voltages on clothing can still cause damage.
