Caution:

Please set 5~10cm gaps around the device for air circulation.

■

Please avoid any heavy thing placed on the device.

■

Please mount devices in sequence from the bottom to top of the rack and ensure a

■

certain clearance between devices for the purpose of heat dissipation.

Cabling Reasonably

21²

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.

Connect to Ground

21³

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 and the 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.

Connecting to the Ground

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.

Equi±otential Bonding

212

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 bellow 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 6mm

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.
