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-ES100 series switch.
The following safety suggestions do not cover all possible dangers.
2.1.1 Installation
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
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 Electricity
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.
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.
Direct or indirect touch through a wet object on high-voltage and mains supply may bring a fatal danger.
If a power supply system is equipped with a leakage protector (also referred to as "leakage current switch" or
"leakage current breaker"), the rated leakage action current of each leakage protector is greater than twice of the
theoretical maximum leakage current of all the power supplies in the system. For example, if a system is equipped
with twenty identical power supplies, the leakage current of each power supply is equal to or less than 1.5mA, and

Ruijie RG-ES100 Series Switches Hardware Installation and Reference Guide Preparation before Installation
the leakage current of the system totals 30mA. A leakage protector with 30mA rated action current supports less
than ten power supplies (that is, Action current of the leakage protector/2/Maximum leakage current of each power
supply =30/2/1.5=10). In other words, the leakage protector with 30mA rated action current supports no more than
ten power supplies. In this case, the twenty power supplies in the system require at least two leakage protectors with
30mA rated action current and each leakage protector supports ten power supplies. If power supplies in a system
differ in models, the rated leakage action current of each leakage protector divided by two is greater than the sum of
maximum leakage current of all the power supplies. The rated leakage non-action current of a leakage protector
shall be 50% of the leakage action current. Take a leakage protector with 30mA rated leakage action current as an
example. The rated leakage non-action current shall be 15mA. When the leakage current is below 15mA, the
protector shall not act. Otherwise, misoperation may easily occur due to high sensitivity and thus the leakage
protector trips, devices are powered off, and services are interrupted.
To guarantee personal safety, the rated leakage action current of each leakage protector in the system must be
equal to or less than 30mA (human body safety current is 30mA). When twice of the total leakage current of the
system is greater than 30mA, the system must be equipped with two or more leakage protectors.
For the leakage current value of each power supply model, see the power supply model parameter table in Chapter
1.
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
The RG-ES126G-P-L 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.

Ruijie RG-ES100 Series Switches Hardware Installation and Reference Guide Preparation before Installation
2.2.1 Ventilation
For the RG-ES100, a sufficient space (at least 10 cm distances from both sides and the back plane of the cabinet) should
be reserved at the ventilation openings to ensure the normal ventilation. After various cables have been connected, they
should be arranged into bundles or placed on the cabling rack to avoid blocking the air inlets. It is recommended to clean
the switch at regular intervals (like once every 3 months). Especially, avoid dust from blocking the screen mesh on the
back of the cabinet.
2.2.2 Temperature and Humidity
To ensure the normal operation and prolong the service life of RG-ES100 series switch, 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-ES100 series must meet the requirements listed in Table 2-1:
Table 2-1 Temperature and Humidity Requirements of the RG-ES100 Series Switch
Temperature
Relative Humidity
0℃to 40℃(32°F to 104°F)
10% to 90%
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
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.

Ruijie RG-ES100 Series Switches Hardware Installation and Reference Guide Preparation before Installation
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 such as sulfur dioxide, sulfured hydrogen, nitrogen dioxide, and
chlorine), whose requirements are listed in Table 2-3.

Both average and maximum value are measured for a week. The switch cannot be placed in the environment with
the maximum density for over 30 minutes every day. ..
2.2.4 EMI
The switch is vulnerable to external interface caused by capacity coupling, inductance coupling, electromagnetic wave
radiation, common impedance (including grounding system) coupling and conducting wires (including power cords, signal
and output wires). Therefore, the following points should be noted:
The AC power supplying system is the TN system. The single-phase three-wire socket with protecting grounding
must be used as the socket for the power supply to enable the device’s upper filter circuit to effective filter the power
interface.
The switch should be far from high-power radio transmitting stations, radar stations and high-frequency and
large-current devices.
Electromagnetic shielding methods should be applied when necessary, such as using the shielded cable as the
interface cable.
Cables must be connected to interfaces inside the room to prevent damage to the device’s signal ports caused by
over-voltage and over-current generated by thunder and lightning.
2.2.5 Grounding
A good grounding system is the basis for the stable and reliable operation of the RG-ES100 series switch. 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.
The grounding cable is customer supplied.
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.
The building must provide protective grounding connection to ensure that the device is connected to the protection
location.

Ruijie RG-ES100 Series Switches Hardware Installation and Reference Guide Preparation before Installation
The installation and maintenance personnel must check whether the A.C. socket is well connected to the protection
location of the building, if not, they should use a protective grounding wire to connect the grounding end of the A.C.
socket to the building's protection location.
The power supply socket must be installed in a place that is near to the device and where users can operate the
device easily.
Before the installation of the device, make sure that ground connection is connected at first and disconnected finally.
The sectional area of the protective grounding wire should be at least 0.75 mm2(18 AWG).
Use the 3-core power supply line. The sectional area of each pin should be at least 0.75 mm2or 18 AWG.
Lightning Grounding
The lightning protection system of a facility is an independent system that consists of the lightning rod, download
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-ES100 series switch back plane is reserved with one grounding pole, as shown in Figure 2-1.
Figure 2-1 Grounding of RG-ES100
2.2.6 Lightning Resistance
When the AC power cable is imported outdoors and directly connected to the power port of the RG-ES100 series 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
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 interference: 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.
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 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.
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.
