• Remove all plastic, vinyl, and foam material from the work area.
• Wear an antistatic wrist strip at all times when handling any CRU.
• Before handling any CRU, discharge any static electricity by touching a grounded surface.
• Do not remove a CRU from its antistatic protective bag until you are ready to install it.
• After removing a CRU from the cabinet, immediately place it in an antistatic bag or antistatic packaging.
• Handle any card CRU only by its edges and avoid touching the components or circuitry.
• Do not slide a CRU over any surface.
• Limit body movement (which builds up static electricity) during the removal and replacement of a CRU.
