To avoid any device damage and bodily injury caused by improper use, please observe
the following rules.
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
■
cloth, and never use any other liquid cleaning method.
Site Requirements

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.

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
L2 Managed Switch
TL-SL3428
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.
■
Keep the device far from high-frequency, strong-current devices, such as radio
■
transmitting station.
Use electromagnetic shielding when necessary.
■
Lightening Protection

In the actual network environment, you may need cable outdoors and indoors, and
the requirements for cabling outdoors and indoors are different. A reasonable cabling
system can decrease the damage of induced lightning to devices.
Note: It’s not recommended using Ethernet cables outdoors. When cabling outdoors,
please use a signal lightning arrester.
Requirements for Cabling Outdoors
■
Aerial cabling without safeguard is not allowed.
■
It’s not allowed cabling down the building to connect network devices in different
■
floors.
Outdoor cables should be buried and paved to the indoor through basement. A piece
■
of steel wire should be paved underground along the pipe and connected to the
lightning protection terminal of the building for shielding. Before connecting the cable
to the device, install a signal lightning arrester on the corresponding port.
When an aerial cable is set up, the cable should be through a metal pipe (15m long
■
at least) before coming into the building. The two ends of this metal pipe should be
grounded. Before connecting the cable to the device, install a signal lightning arrester
on the corresponding port.
It’s not necessary to pave STP cables through pipes. The shielded layer of STP cable
■
should be well grounded. Before connecting the cable to the device, install a signal
lightning arrester on the corresponding port.
Requirements for Cabling Indoors
■
When cabling indoors, keep a certain distance away from the devices that may cause
high-frequency interferences, such as down-conductor cable, powerline, power
transformer and electromotor.
The main cable should be paved in the metal raceway of the access shaft. When
■
cabling, keep the loop area formed by the cable itself as small as possible.

Connecting the device to ground is to quickly release the lightning over-voltage and
over-current of the device, which is also a necessary measure to protect the body from
electric shock.
In different environments, the device may be grounded differently. The following
will instruct you to connect the device to the ground in two ways, connecting to the
grounding bar or connecting to the ground via the power cord. Please connect the
device to ground in the optimum way according to your specific operation environment.
Connecting to the Grounding Bar
■
If the device is installed in the Equipment Room, where a grounding bar is available,
you are recommended to connect the device to the Grounding Bar as shown in the
following figure.

Note: The grounding bar is not provided with our product. If needed, please self

If the device is installed in the normal environment, the device can be grounded via the
PE (Protecting Earth) cable of the AC power supply as shown in the following figure.

■
of AC power cord, please make sure the PE (Protecting Earth) cable in the electrical
outlet is well grounded in advance.

Equipotential Bonding is the practice of intentionally electrically connecting all earthed
systems to the same grounding grid or connecting the grounding grids of all the
earthed systems together through the ground or overground metal so as to create
an earthed equipotential zone. When lightning occurs, the high voltage produced by
lightning current in all systems will meanwhile exist in their ground cables, and thus
all ground cables have the same electrical potential and basically eliminate the electric
strikes between the systems.
The figure below illustrates how to practice equipotential bonding in a network.
Grounding T e rminal Equipotential Bonding Cable
Grounding BarGround Cable
Equipotential BondingFigure 3-3
When equipotential bonding, please note that the cable should be copper wrapped Kelly
with its area being 6mm2at least. The shorter cable the better, and use a grounding
bar to establish an equipotential bonding point.
Note: The equipotential bonding cable is not provided with our product. If needed,

Power lightning arrester and signal lightning arrester are used for lighting protection.
Power lightning arrester is used for limiting the voltage surge due to a lightning. If an
outdoor AC power cord should be directly connected to the device, please use a power
lightning arrester.
Note: Power lightning arrester is not provided with our product. If needed, please self
purchase it.
Signal lightning arrester is used to protect RJ45 ports of the device from lightning.
When cabling outdoors, please install a signal lightning arrester before connecting the
cable to the device.
When purchasing or using a signal lightning arrester, please observe the following
rules:
The port rate of the signal lightning arrester should match the rate of the desired port
■
on the device. If it is not matched, this signal lighting arrester will not work. Purchase
a standard lightning arrester.
Install signal lightning arrester near the protected device and connect it to the
■
ground via a shorter ground cable.
