Chapter 3 Lightning Protection
3.1 Cabling Reasonably
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.

3.2 Connect to Ground
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.
Switch (Rear Panel)
Ground Cable
Grounding Terminal

Figure 3-1 Connecting to the Grounding Bar
Note: The grounding bar and ground cable are not provided with our product. If
needed, please self purchase them.
■Connecting to the Ground via the Power Supply
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.
Figure 3-2 Connecting to the Ground
Lightning Protection

11
L2 Managed Switch
Note:
■The figure is to illustrate the application and principle. The power cord you get from
the package and the socket in your situation will comply with the regulation in your
country, so they may differ from the figure above.
■If you intend to connect the device to the ground via the PE (Protecting Earth)
cable of AC power cord, please make sure the PE cable in the electrical outlet is well
grounded in advance.
3.3 Equipotential Bonding
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 Terminal Equipotential Bonding Cable
Grounding BarGround Cable
Figure 3-3 Equipotential Bonding
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,
please self purchase it.

3.4 Use Lightning Arrester
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.

4.2 SFP Port
Connect the SFP port to a SFP module. For the switch, if an SFP transceiver (purchased
separately) is installed in a slot and has a valid link on the port, the associated RJ45
port will be disabled and cannot be used. Figure 4-2 demonstrates the connection of
SFP port to a SFP module.
TL-SG5428
SFP Slot
Figure 4-2 Inserting the SFP Module
Note:
■A Combo port refers to two Ethernet interfaces in a device panel (normally one
is an SFP slot and the other is an RJ45 port). Inside the device there is only one
forwarding interface. Users can choose one to use depending on the actual network
requirements, but not two simultaneously. When one port is working, the other is
disabled.
■For a Combo port, the SFP slot takes priority over its associated RJ45 port. When
the SFP slot and its associated RJ45 port are both connected, whatever the priority
of connection, the SFP port will always work normally while the RJ45 port will be
disabled.
SFP Module
Optical Fiber

14
L2 Managed Switch
Connection
Optical fiber
Optical fiber can be used as a medium for telecommunication and computer networking. It is especially
advantageous for long-distance communications, because light propagates through the fiber with much
less attenuation compared to electrical cables. For short distance applications, such as a network in an
office building, optical fiber permits transmission over longer distances and at higher bandwidths (data
rates) than other forms of communication. Fibers are used instead of metal wires because signals travel
along them with less attenuation and are also immune to electromagnetic interference. There is no cross-
talk between signals in different cables, and no pickup of environmental noise.
SFP Module
SFP module are input/output (I/O) devices that plug into a Gigabit Ethernet port, linking the port with
a 1000BASE-X fiber-optic network. A SFP module possesses a receiver port (RX) and a transmitter port
(TX) that make up one optical interface. To enjoye the required optical reach, users can freely select the
appropriate SFP module over the available optical fiber type such as multi-mode fiber or single-mode fiber.
Multi-mode fibers generally have a larger core diameter, and are used for short-distance communication
links and for applications where high power must be transmitted. Single-mode fibers are used for most
communication links longer than 1,050 meters that is 3,440 feet.
TL-SG5428 and TL-SG5412F are compatible with all kinds of gigabit SFP modules including sigle-mode and
multi-mode. The transmission distance and the type of optical fiber are determined by the SFP module
you choose. Here you are recommanded to choose the SFP modules produced by TP-LINK, which can
perfectly enlarge the bandwidth and extend your network.
Figure 4-3 SFP module
The following table shows the detailed information of two SFP modules (TL-SM311LS and TL-SM311LM)
produced by TP-LINK, which makes you have a round idea about it so as to give you a reference for
choosing the suitable SFP module.
