Take these ESD precautions:
• Prepare an ESD-safe work surface large enough to accommodate the various assemblies to be handled
during servicing. Use a grounding mat and an anti-static wrist strap, such as those included in the ESD
Field Service Kit (A3024-80004).
• Do not use the anti-static bag for any purpose other than to enclose a product. The anti-static bag that
encloses new or repaired FRUs cannot function as a static dissipating mat.
• Treat all assemblies, components, and interface connections as static-sensitive.
• Keep replacement and removed FRUs in a conductive plastic bag until they are ready to be installed or
shipped for repair.
• Avoid working in carpeted areas, and keep body movement to a minimum while removing and installing
FRUs.
