Preparing for installation
ESD prevention
To prevent electronic components from electrostatic discharge (ESD) damage, wear an ESD wrist strap
and make sure it makes good skin contact and is reliably grounded before you touch any switch
module.

Examining the installation site
The switch must be used indoors. To make sure the switch operates correctly and to prolong its service
lifetime, the installation site must meet the load-bearing, temperature, humidity, cleanness, EMI,
grounding, power supply, ventilation, and space requirements. Reserve a minimum of 1.2 m (3.94 ft) of
clearance between the switch and walls or other devices. For more information, see H3C S12500X-AF
