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”.
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.
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.
The clapboard separates exhaust gas and inflow air, and boost cool air to flow in the machine
box. The best location of the clapboard is decided by the air flow mode in the machine box,
which can be obtained through different location tests.
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.
Warning
If the power supply system does not have good grounding, or the input power disturbs too much
and excessive pulses exist, the error code rate of communication devices increases and even the
hardware system will be damaged.
