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 module, use any available ejector levers or captive installation screws to properly
seat the bus connectors in the backplane or module 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 module, use any available ejector levers or captive installation screws to release the
bus connectors from the backplane or module slot.
•
Handle adapter modules by available handles or edges only. Avoid touching the printed circuit boards
or connectors.
•
Place a removed module board-side-up on an antistatic surface or in an approved antistatic container.
•
If you need to return the module to Lucent, immediately place it in a static shielding container.
•
Avoid contact between printed circuit boards and clothing. A wrist or ankle strap only protects
components from ESD voltages on the body; ESD voltages on clothing can still cause damage.
