2.3 Electrostatic Discharge (ESD) Precautions
Observe these guidelines to avoid ESD damage when installing or servicing the switch.
• Assemble or disassemble equipment only in a static-free work area.
• Use a conductive work surfaces (such as an anti-static mat) to dissipate static charge.
• Wear an ESD wrist strap to dissipate static charge accumulation.
• Minimize handling of assemblies and components.
• Keep replacement parts in their original static-free packaging.
• Remove all plastic, foam, vinyl, paper, and other static-generating materials from the work area.
• Use tools that do not create ESD.
