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.
z
Make sure that the workshop is well-ventilated, the heat of TX devices is
well-discharged and sufficient air circulation is provided for device cooling.
z
Avoid to damage devices by following the electrostatic discharge prevention
procedure.
z
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 Cabinet Configuration
The following content assists you to make a proper cabinet configuration:
z
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.
z
When you install the chassis at the open cabinet, prevent the frame of the
cabinet from blocking the airway of the chassis.
