Safety Precautions

Keep the power off during the installation.

Wear an ESD-preventive wrist strap, and make sure that the wrist strap has a good

skin contact and is well grounded.
Use only the power cord provided with the Switch.

Make sure that the supply voltage matches the specifications indicated on the rear

panel of the Switch.
Ensure the vent hole is well ventilated and unblocked.

Do not open or remove the cover of the Switch.

Before cleaning the device, cut off the power supply. Do not clean it by the waterish

Site Requirements

To ensure normal operation and long service life of the device, please install it in an
environment that meets the requirements described in the following subsection.
Temperature/Humidity
ȭ
ȭ
Please keep a proper temperature and humidity in the equipment room. Too high/low
humidity may lead to bad insulation, electricity leakage, mechanical property changes
and corrosions. Too high temperature may accelerate aging of the insulation materials
and can thus significantly shorten the service life of the device. For normal temperature
and humidity of the device, please check the following table.
Environment Temperature Humidity
Operating 0℃~ 40℃10% ~ 90%RH Non-condensing
Storage -40℃~ 70℃5% ~ 90%RH Non-condensing
Clearness
The dust accumulated on the Switch can be absorbed by static electricity and result
in poor contact of metal contact points. Some measures have been taken for the
device to prevent static electricity, but too strong static electricity can cause deadly
damage to the electronic elements on the internal circuit board. To avoid the effect of
static electricity on the operation of the Switch, please attach much importance to the
following items:
Dust the device regularly, and keep the indoor air clean.

Keep the device well grounded and ensure static electricity has been transferred.

Electromagnetic Interference
Electronic elements including capacitance and inductance on the device can be affected
by external interferences, such as conducted emission by capacitance coupling,
inductance coupling, and impedance coupling. To decrease the interferences, please
make sure to take the following measures:
Use the power supply that can effectively filter interference from the power grid.
