Adaptec SCSI RAID 2120S/2200S Installation Guide

Electrostatic Discharge

Electrostatic discharge (ESD) is a natural by-product of human
activity. ESD is transmitted by materials that retain and accumulate
electrical charges.
!
Caution: ESD can damage electronic components when they
are improperly handled and can result in complete or
intermittent failures. Always follow ESD-prevention
procedures when removing and replacing components.
To prevent ESD damage, follow these guidelines:
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 or removing 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.
Handle adapter cards by available handles or edges only. Avoid
■
touching the printed circuit boards or connectors.
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.
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 Adaptec, immediately
■
place it in a static-shielding container.
