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
Temperature/Humidity

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.

Clearness

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

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.

Lightning Protection

Extremely high voltage currents can be produced instantly when lightning occurs and the air in the electric discharge path can be instantly heated up to 20,000℃. As this instant current is strong enough to damage electronic devices, more effective lightning protection measures should be taken.

• Ensure the rack and device are well earthed.
• Make sure the power socket has a good contact with the ground.
• Keep a reasonable cabling system and avoid induced lightning.
• Use the signal SPD (Surge Protective Device) when wiring outdoor.

Note: For detailed lightning protection measures, please refer to Chapter 3 Lightning Protection.

Lightning Protection

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.

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

The two diagrams below demonstrate parallel net length and parallel- overlapping net
height.

Note: The above minimum net length/height is required when metal raceway is not used. If any requirements cannot be met, you can add a steel tube or metal raceway for shielding.

• Requirements for the distance between Ethernet cable and high-power electric
  devices are in following tables.

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.

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

Figure 3-1 Connecting to the Grounding Bar

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.

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

Figure 3-2 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.

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.

1. Grounding Terminal
2. Equipotential Bonding Cable
3. Ground Cable
4. Grounding Bar

Figure 3-3 Equipotential Bonding

When equipotential bonding, please note that the cable should be copper conductor
with a sectional area of 6mm2 at least, wrapped green with yellow stripe. 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.
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.
