Electronic equipment is susceptible to damage by static electricity. Use a grounded antistatic wrist strap, foot strap, or equivalent safety equipment to prevent electrostatic discharge damage when you install or service the server.
Caution - To protect electronic components from ESD, which can permanently disable the server or require repair by service technicians, place components on an antistatic surface, such as a grounded antistatic discharge mat. Wear an antistatic grounding strap connected to a metal surface on the chassis when you work on server components.
Caution - ESD is easily generated and less easily dissipated in areas where the relative humidity is below 35%, and becomes critical when levels drop below 30%.
