2.2.2 Installing Device onto Desktop
In many cases, users do not have a standard 19” rack, so people often place switches on a cleaning working
platform. Such operation is relatively simple, and the only following aspects should be concerned during
operation:
 Ensure the working platform is stable and well grounded.
 A 10 cm space around switch is left for heat dissipation.
 Do not place heavy objects on switches.
