2.2.4 Electrostatic Discharge Prevention
Electrostatic discharge may damage devices and circuits. Improper treatment may cause the switch to
malfunction completely or discontinuously.
Move or locate the devices according to the measures of electrostatic discharge prevention, ensuring
the chassis connects the ground. Another measure is to wear the static-proof hand ring. If there is no
hand ring, use the metal clip with the metal cable to clip the unpainted metal part of the chassis. In
this case, the static is discharged to the ground through the metal cable of the clip. You can also
discharge the static to the ground through your body.
2.3 Requirements for Common Locations
This part describes the requirements for the installation locations.
2.3.1 Environment
The switch can be installed on the desk or the cabinet. The location of the chassis, cabinet planning
and indoor cabling are very important for normal system’s function. Short distance between devices,
bad ventilation and untouchable control plate will cause maintenance problems, systematic faulty and
breakdown.
For location planning and device locating, refer to section 2.3.2 “Location Configuration Prevention”.
2.3.2 Location Configuration Prevention
The following preventive measures assist you to design the proper environment for the switch.
Make sure that the workshop is well-ventilated, the heat of
electrical devices is well-discharged and sufficient air circulation is
provided for device cooling.
Avoid to damage devices by following the electrostatic discharge
prevention procedure.
Put the chassis at the place where cool air can blow off the heat
inside the chassis. Make sure the chassis is sealed because the
opened chassis will reverse the cool air flow.
2.3.3 Power Requirements
Make sure that the power supply has nice grounding and the power at the input side of the switch is
reliable. The voltage control can be installed if necessary. At least a 240 V, 10A fuse or a breaker is
provided in the phase line if you prepare the short-circuit prevention measures for a building.
