A grounded antistatic wrist strap is shipped with your switch. Electronic equipment is susceptible to damage by static electricity. Use a grounded antistatic wrist strap, foot strap, or equivalent safety equipment to prevent ESD when you install or service the switch.
Caution - To protect electronic components from electrostatic damage, which can permanently disable the switch or require repair by service technicians, place components on an antistatic surface, such as an antistatic discharge mat, an antistatic bag, or a disposable antistatic mat. Wear an antistatic grounding strap connected to a metal surface on the switch when you work on switch components.
