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.

12
JetStream Smart Switch
Lightning Protection
■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.
■Requirements for the distance between Ethernet cable and other pipelines are shown
in the table.

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 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.

JetStream Smart Switch
Lightning Protection
Note:
■The figure is to illustrate the application and principle. The power plug 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 (Protecting Earth) cable in the electrical outlet
is well grounded in advance.
■Connecting to the Grounding Bar
Use 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

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.

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 and ground cable are not provided with our
product. If needed, please self purchase it.
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.
