2 Preparation before Installation

2.1 Safety Suggestions

To avoid personal injury and equipment damage, please carefully read the safety suggestions before you install the
RG-S2900G-E series.

The following safety suggestions do not cover all possible dangers.

2.1.1 Safety Precautions for Installing the System

 Keep the chassis clean and free from any dust.
 Do not place the equipment in a walking area.
 Do not wear loose clothes or accessories that may be hooked or caught by the device during installation and

maintenance.

 Turn off all power supplies and remove the power sockets and cables before installing or uninstalling the device.

2.1.2 Movement Safety

 Do not frequently move the device.
 When moving the device, note the balance and avoid hurting legs and feet or straining the back.
 Before moving the device, turn off all power supplies and dismantle all power modules.

2.1.3 Electric Safety

 Observe local regulations and specifications when performing electric operations. Relevant operators must be

qualified.

 Before installing the device, carefully check any potential danger in the surroundings, such as ungrounded power

supply, and damp/wet ground or floor.

 Before installing the device, find out the location of the emergency power supply switch in the room. First cut off the

power supply in the case of an accident.

 Try to avoid maintaining the switch that is powered-on alone.
 Be sure to make a careful check before you shut down the power supply.
 Do not place the equipment in a damp location. Do not let any liquid enter the chassis.

1. Any nonstandard and inaccurate electric operation may cause an accident such as fire or electrical shock, thus
causing severe even fatal damages to human bodies and equipment.

2. Direct or indirect touch through a wet object on high-voltage and mains supply may bring a fatal danger.

2.1.4 Static Discharge Damage Prevention

To prevent damage from static electricity, pay attention to the following:

 Proper grounding of grounding screws on the back panel of the device. Use of a three-wire single-phase socket with

protective earth wire (PE) as the AC power socket.

 Indoor dust prevention
 Proper humidity conditions

2.1.5 Laser Safety

The RG-S2900G-E series switch supports varying models of optical modules sold on the market which are Class I laser
products. Improper use of optical modules may cause damage. Therefore, pay attention to the following when you use
them:

 When a fiber transceiver works, ensure that the port has been connected with an optical fiber or is covered with a

dust cap, to keep out dust and avoid burning your eyes.

 When the optical module is working, do not pull out the fiber cable and stare into the transceiver interface or you may

hurt your eyes.

Do not stare into any optical port under any circumstances, as this may cause permanent damage to your eyes.

2.2 Installation Site Requirements

To ensure the normal working and a prolonged durable life of the equipment, the installation site must meet the following
requirements.

2.2.1 Ventilation Requirements

For the RG-S2900G-E series, you must ensure that sufficient space (10 cm distance from both sides and the back panel
of the cabinet) is reserved at the ventilation openings to ensure the normal ventilation. During the jumper process of the
device, prevent the cables from blocking the cellular heat dissipation holes around the device. Be especially careful for the
RG-S2928G-E device. This high-speed forwarding device adopts the fan-free design; therefore, it has high requirement
for heat dissipation of the operating environment. Dust the device every three months to avoid blocking the ventilation

openings.

2.2.2 Temperature and Humidity Requirements

To ensure the normal operation and prolong the service life of RG-S2900G-E series, you should keep proper temperature
and humidity in the equipment room.

If the equipment room has temperature and humidity that do not meet the requirements for a long time, the equipment
may be damaged.

 In an environment with high relative humidity, the insulating material may have bad insulation or even leak electricity.

Sometimes the materials may suffer from mechanical performance change and metallic parts may get rusted.

 In an environment with low relative humidity, however, the insulating strip may dry and shrink. Static electricity may

occur easily and endanger the circuit on the equipment.

 In an environment with high temperature, the equipment is subject to even greater harm, as its performance may

degrade significantly and various hardware faults may occur. .
Therefore, the ambient temperature and humidity of the RG-S2900G-E must meet the requirements listed in Table 2-1:
Table 2-1 Temperature and Humidity Requirements of the RG-S2900G-E Series

Temperature

Relative Humidity

0ºC to 50ºC

10% RH to 90% RH

The requirements for the sampling site of the temperature and humidity in the operating environment of the device

are as follows:

There is no protective plate at the front or back of the equipment rack.

The vertical height is 1.5 m above the floor.

The distance from the front panel of the equipment is 0.4 m.

2.2.3 Cleanness Requirements

Dust poses a severe threat to the running of the equipment. The indoor dust falling on the equipment may be adhered by
the static electricity, causing bad contact of the metallic joint. Such electrostatic adherence may occur more easily when
the relative humidity is low, not only affecting the useful life of the equipment, but also causing communication faults.
Table 2-2 shows the requirements for the dust content and granularity in the equipment room.

Table 2-2 Requirements for the Dust Content and Granularity in the Equipment Room

Substance

Concentration Limit (particles/m3)

Dust particles (diameter ≥0.5μm)

≤3.5×106

Dust particles (diameter ≥5μm)

≤3×104

Apart from dust, the salt, acid and sulfide in the air in the equipment room must also meet strict requirements; as such
poisonous substances may accelerate the corrosion of the metal and the aging of some parts. The equipment room
should be protected from the intrusion of harmful gases (for example, SO2, H2S, NO2 and Cl2), whose requirements are
listed in the following table.

Table 2-3 Requirements for Harmful Gases in the Equipment Room

The Average refers to the average limit of harmful gas in one week. The Maximum value is the upper limit of the

harmful gas measured in one week for up to 30 minutes every day.

2.2.4 EMI

During applications, the switch may be subject to external interferences that affect the device through conduction manners
such as capacitance coupling, inductive coupling, electromagnetic wave emission, common impedance (including
grounding systems), and wires (power cables, signal cables and outgoing transmission cables). For that purpose, note
that:

 For the AC power supply system TN, single-phase three-core power socket with protective earthing conductors (PE)

should be adopted to effectively filter out interference from the power grid through the filtering circuit.

 The switch should be located at places free from large power radio launch pad, radar launch pad, and

high-frequency large-current devices.

 If necessary, electromagnetic shielding should be adopted. For example, use interface cables to shield cables.
 Interface cables should be laid inside the equipment room. Outdoor cabling is prohibited, avoiding damages to

device signal interfaces caused by over-voltage or over-current of lightning.

2.2.5 System Grounding Requirements

A good grounding system is the basis for the stable and reliable operation of the RG-S2900G-E series. It is the chief
condition to prevent lightning stroke and resist interference. Please carefully check the grounding conditions on the
installation site according to the grounding requirements, and perform grounding operations properly as required.

Effective grounding of the switch is an important guarantee for lightning protection and interference resistance.

Therefore, connect the grounding line of the switch properly..

Safety Grounding

The equipment using AC power supply must be grounded by using the yellow/green safety grounding cable. Otherwise,
when the insulating resistance decreases the power supply and the enclosure in the equipment, electric shock may occur.

Lightning Grounding

The lightning protection system of a facility is an independent system that consists of the lightning rod, downlead
conductor and the connector to the grounding system, which usually shares the power reference ground and yellow/green
safety cable ground. The lightning discharge ground is for the facility only, irrelevant to the equipment.

EMC Grounding

The grounding required for EMC design includes shielding ground, filter ground, noise and interference suppression, and
level reference. All the above constitute the comprehensive grounding requirements. The resistance of earth wires should
be less than 1 ohm. The RG-S2900G-E backplane is reserved with one grounding pole, as shown in Figure 2-1.

Figure 2-1 Schematic Diagram of the RG-S2900G-E Grounding

2.2.6 Lightning Resistance Considerations

When the AC power cable is imported outdoors and directly connected to the power port of the switch, lightning line bank
should be adopted to prevent the switch from being hit by lightning shocks. Usage of the lightning line bank: Connect the
mains supply AC cable to the lightning line bank. Then, connect the switch to the lightning line bank. This can help to
prevent the current of high-voltage lightning from passing the switch directly through the mains supply cable to a certain
extent.

The lightning line banks are not provided and should be purchased by users as required.

For the usage of lightning line banks, refer to their related manuals.

2.2.7 EMI Consideration

Electro-Magnetic Interference (EMI), from either outside or inside the equipment or application system, affects the system
in the conductive ways such as capacitive coupling, inductive coupling, and electromagnetic radiation.

There are two types of electromagnetic interferences: radiated interference and conducted interference, depending on the
type of the transmission path.

When the energy, often RF energy, from a component arrives at a sensitive component via the space, the energy is
known as radiated interference. The interference source can be either a part of the interfered system or a completely
electrically isolated unit. Conducted interference results from the electromagnetic wire or signal cable connection between
the source and the sensitive component, along which cable the interference conducts from one unit to another. Conducted
interference often affects the power supply of the equipment, but can be controlled by a filter. Radiated interference may
affect any signal path in the equipment and is difficult to shield.

 Effective measures should be taken for the power system to prevent the interference from the electric grid.
 The grounding device of the switch must not be used as the grounding device of the electrical equipment or

anti-lightning grounding device. In addition, the grounding device of the switch must be deployed far away from the

grounding device of the electrical equipment and anti-lightning grounding device.

 Keep the equipment away from high-power radio transmitter, radar transmitting station, and high-frequency

large-current device.

 Measures must be taken to shield static electricity.

Appendix C Site Selection

 The machine room should be at least 5km away from the heavy pollution source such as the smelter, coal mine and

thermal power plant, 3.7km away from the medium pollution source such as the chemical industry, rubber industry

and electroplating industry, and 2km away from the light pollution source such as the food manufacturer and leather

plant. If the pollution source is unavoidable, the machine room should be located on the windward side of the

pollution source perennially with advanced protection.

 The machine room should be at least 3.7km away from the sea or salt lake. Otherwise, the machine room must be

sealed, with air conditioner installed for temperature control. Saline soil cannot be used for construction. Otherwise,

you should select devices with advanced protection against severe environment.

 Do not build the machine room in the proximity of livestock farms. Otherwise, the machine room should be located

on the windward side of the pollution source perennially. The previous livestock house or fertilizer warehouse cannot

be used as the machine room.

 The machine room should be firm enough to withstand severe weather conditions such as windstorm and heavy rain

as well as away from dust. If the dust is unavoidable, keep the door and window away from the pollution source.

 The machine room should be away from the residential area. Otherwise, the machine room should meet the

construction standard in terms of noise.

 Make sure the air vent of the machine room is away from the sewage pipe, septic tank, and sewage treatment tank.

Keep the machine room under positive pressure to prevent corrosive gas from entering the machine room to corrode

components and circuit boards. Keep the machine room away from industrial boiler and heating boiler.

 The machine room had better be on the second floor or above. Otherwise, the machine room floor should be 600mm

higher than the highest flood level ever recorded.

 Make sure there are no cracks or holes in the wall and floor. If there are cable entries in the wall or window, take

proper sealing measures. Ensure that the wall is flat, wear-resistant, and dust-free, which should be up to the

standard for flame retarding, soundproofing, heat absorption, dust reduction, and electromagnetic shielding.

 Keep the door and the window closed to make the machine room sealed.
 The steel door is recommended for soundproofing.
 Sulfur-containing materials are forbidden.
 Pay attention to the location of the air conditioner. Keep the air conditioner from blowing wind straight toward the

device or blowing water drops from the window or air vent toward the device.
