    C["Building 2"] --> B
    style A fill:#f9f,stroke:#333
    style C fill:#f9f,stroke:#333

- 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.

- Requirements for the distance between Ethernet cable and other pipelines are shown in the table.

Other Pipelines	Ethernet Cable
	Min Parallel Net Length L (mm)	Min Parallel-overlapping Net Height H (mm)

Connect to Ground3.2

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.

① Switch (Rear Panel)
② Grounding Terminal
③ Ground Cable
④ Grounding Bar

Connecting to the Grounding BarFigure 3-1

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

■ 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.

① Switch (Rear Panel)
② AC Power Cord (with PE cable)

Connecting to the GroundFigure 3-2

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 (Protecting Earth) cable in the electrical outlet is well grounded in advance.

Equipotential Bonding3.3

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.

① Grounding Terminal Equipotential Bonding Cable
③
④ Grounding Bar Ground Cable
Equipotential BondingFigure 3-3

When equipotential bonding, please note that the cable should be copper wrapped Kelly with its area being 6mm ^2 at 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.

Use Lightning Arrester3.4

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.

Lightning Arrester ConnectionFigure 3-4

Note:

• Signal lightning arrester is not provided with our product. If needed, please self purchase it.
• The SFP ports performe transmission by optical fiber which is immune to electric conduction. Therefore, 3.4 Use Lightning Arrester is not appropriate for SFP ports but only applies to RJ45 ports.

ConnectionChapter 4

Ethernet Port4.1

Connect the Ethernet ports of the Switch to the network devices by RJ45 cable as the following figure shown.

Connecting the RJ45 PortFigure 4-1

SFP Port4.2

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.

Inserting the SFP ModuleFigure 4-2

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.

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 enjoy 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 recommended to choose the SFP modules produced by TP-LINK, which can perfectly enlarge the bandwidth and extend your network.
