liquid to wipe or wash the switch;
Do not leave the switch close to water or wet place so as to prevent water or
dampness from entering into the switch;
Make sure the switch work in a clean environment. Excessive dust may
cause electrostatic adsorption, which will affect the equipment life and cause
communication failure;
The switch will work normally under the correct voltage. Please ensure the
voltage indicated on the switch corresponds to the power voltage;
To avoid the danger of electric shock, please do not open the switch case.
Do not open the switch case even if the switch is powered off;
The accessories (including but not limited to power cables, etc.), which can

2.2.2 Installation Requirements
The device should work in indoor environment to avoid thunder stroke. It is
important to obey the following requirements no matter you install it in the
cabinet or on the workbench directly:
Enough space (larger than 10cm) for air outlet so as to facilitate the
heating dissipation; Good ventilation system for cabinets and workbench
is preferred;
Ensure the Cabinet and workbench is sturdy enough to support the
switch and it's accessories's weight;
Cabinet and workbench with good grounding is preferred.
2.2.3 The Requirements of Electromagnetic Environment
When it is working, the switch may be affected by external interference outside
the system through the ways of radiation and conduction. Please pay attention
to the followings:
AC power supply is TN system, so it is necessary to use single phase power
socket (PE) which can protect ground wire so that the filter circuit can
effectively filter out the power grid disturbances;
The switch should work far away from high-power radio transmitters, radar
transmitters, high-frequency devices;
Use electromagnetic shielding if necessary, such as shielded cable;
Interface cables should be arranged indoor rather than outdoor to prevent
over-voltage or over-current damage to the signal port.

2.3 Installation Way
There are 3 installation ways: rack, workbench and
Caution
Please pull out the power plug before installing or moving the switch.
Grounding and anti-lightening can greatly increase the protection level of the
switch. please connect the grounding terminal to the earth area by using at
least wire 20.
