2.2.4 Electrostatic Discharge Damage 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 machine box 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 machine box. 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 Environment
The switch can be installed on the desk or the cabinet. The location of the machine box,
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
”.
2.3.1 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 machine box at the place where cool air can blow off the heat inside the
machine box. Make sure the machine box is sealed because the opened machine
box will reverse the cool air flow.
2.3.2 Cabinet Configuration
The following content assists you to make a proper cabinet configuration:
Each device on the cabinet gives off heat when it runs. Therefore, the sealed cabinet
must have the heat-discharge outlet and the cooling fan. Do not put the devices too
close, avoiding bad ventilation.
When you install the machine box at the open cabinet, prevent the frame of the
cabinet from blocking the airway of the machine box.
Ensure that nice ventilation is provided for the devices installed at the bottom of the
cabinet.
