2.1 Preparation before installation
2.1.1 Safety warning
To avoid device damage and personal injuries caused by improper usage, please conform to
the following precautions:
The power supply should be unplugged before cleaning switch. Don’t use wet duster
cloth to wipe the switch, or use liquid to wash the switch.
Don’t place the switch beside water or in a moist place, and prevent water or moisture
from entering the enclosure of the switch.
Don’t place the switch on unstable boxes or tables, to avoid major damage to the switch
in case of falling down.
Keep good ventilation indoor and keep the venthole of the switch unblocked.
The switch can work normally only under correct voltage, please confirm that the
working voltage conforms to the voltage indicated by the switch.
To reduce the risk of electronic shock, don’t open the enclosure when the switch is
working, and don’t open the enclosure of the switch randomly even though it isn’t
powered on.
The electro-static dissipative (ESD) gloves must be used when replacing the interface
board, to prevent the static electricity from damaging the single board.
2.1.2 Pre-installation check
To ensure normal working environment of switch, S2100P switches have the following
requirements for workplaces:
Confirm that there is space left at the air intake vent and ventilation opening of switch, so
as to facilitate the heat dissipation of the crate of switch.
Confirm that the rack and workbench have good ventilation and heat dissipation system
themselves.

S2100P-8T2S Installation Instruction Manual
2 Installation instruction
NADDOD Pte. Ltd.

Confirm that the rack and workbench are solid enough, and can bear the weight of switch
and its installation accessories.
Confirm that the rack and workbench are grounded properly.
To ensure long-term stable work of switch, the installation place should also meet the
following several requirements:
Requirements for temperature and humidity
To ensure normal operation and service life of switches, it’s necessary to keep certain
temperature and humidity in the machine room. Where the humidity in the machine room is
too high for a long term, it’s easy to cause poor insulation performance of insulating materials
and even electric leakage, and it’s also easy to cause change in mechanical performance of
materials, corrosion of metal components and other phenomenon sometimes; where the
relative humidity is too low, the fastening screw may be loosened by the air shrinkage of
insulating spacer, and meanwhile it’s easy to generate static electricity in dry climate
environment and damage the circuit of switch; too high temperature is more hazardous,
long-term high temperature will accelerate the aging of insulating materials, reduce greatly
the reliability of switch, and affect significantly its service life.

Items

Relative humidity in working
environment (incondensable)
10%～95%
Cleanliness requirement
Dust is a main hazard for the operation safety of switch. The dust accumulated on the machine
indoor may cause electrostatic adsorption, which may cause poor contact of metal connectors
or metal contact points. In particular, when the relative humidity indoor is too low, it’s easier
to cause electrostatic adsorption, which may not only affect the service life of device, but also
improve the risk of communication fault.

Note: The diameters of dust particles are ≥5um
In addition to dust, the machine rooms of switches also have strict requirements for the
content of salt, acid and sulfide in the air. Such harmful gases will accelerate the corrosion of

metal and aging of certain components. Harmful gases, such as SO2, H2S, NH3 and Cl2 shall
be kept away from the machine rooms.

Anti-interference requirements
The switches may be affected by external interference of the system during usage through
such conduction methods as capacity coupling, inductive coupling, electromagnetic radiation,
common impedance (including grounding system) coupling and wires (power line, signal line,
output line, etc.).
For this purpose, it should be noted that:
The alternating current power supply system is TN system, the alternating current power
socket should adopt single-phase three-wire power socket with protective earth wire (PE),
to allow the filter circuit on the device to filter the interference of power grid effectively.
Keep the workplace of switches far away from high power radio launcher, radar launcher,
high frequency high current equipment.
Adopt electromagnetic shielding method if necessary, for example, the interface cables
adopt shield cables.
The interface cables are required to cable indoor, and cabling outdoor is prohibited, so as
to prevent overvoltage and overcurrent caused by thunder from damaging the signal port
of devices.
Laser usage safety
This series switches belong to Class 1 laser devices.
If the optional fiber interface boards of this series switches are in working state, don’t look
straight at these fiber interfaces, because the light beams of the optical fiber have energy at a
very high level, which may harm the retina.
2.1.3 Installation tools
Before installation, please prepare the following tools:

S2100P-8T2S Installation Instruction Manual
2 Installation instruction
NADDOD Pte. Ltd.
14
Electro-static dissipative (ESD) wrist strap
Phillips screwdriver or One-word screwdriver
Left and right guide rails (optional)
Floating nuts
Racking screws
No installation tool is attached to the switches, the users should prepare installation tools by themselves.
2.2 Installation
S2100P-8T2S switches adopt two installation methods as follows:
Installing the switch with front mounting brackets and rack rails
Installing the switch to the desktop.
2.2.1 Mounting bracket introduction
Figure 2-2 Diagram of front mounting brackets
Instruction:
(1): The screw holes for front mounting brackets to be fixed on the rack
(2): The screw holes for front mounting brackets to be fixed on the switch
Front mounting brackets are only for fixing the switch and can’t be used for load-bearing.

2.2.2 Install with front mounting brackets and rack rails
Installation procedures
Step 1: Wear an electro-static dissipative (ESD) wrist strap and check the grounding and
stability of rack.
Step 2: Fix the rail attached to the rack horizontally to proper positions of the rack.
Step 3: Take out the screws (packed with front mounting bracket), install one end of each
front mounting bracket to the switch
Figure 2-3 Installation diagram of front mounting brackets
Step 4: Place the switch horizontally on the rail, push it gently into the rack along the rail, fix
the other end of each front mounting bracket to the front mounting rails of rack with screws
and supporting floating nuts.

2.2.3 Installing the switch to the desktop
Usually, users don’t have 19-inch standard racks, in which case people usually place the
switch on the clean workbench simply.
During the operation, pay attention to the following precautions:
Guarantee the stability and good grounding of workbench.
Leave 10cm clearance around the switch for heat dissipation.
Don’t place heavy items on the switch.
4-foot pads are attached to the device, please paste them to the places near to the corners
respectively at the bottom of the switch, as shown in the following diagram:

Figure 2-5 Installation diagram of foot pads
2.2.4 Ground wire connection
The power supply input terminals of switch are connected to a noise filter, whose central
place is directly connected to the crate, which is referred to as enclosure place (i.e., protected
area) and must be grounded properly, so as to make induction electricity and leakage
electricity be able to flow to the earth safely, and improve the capacity of anti-electromagnetic
interference of switch.
Correct grounding method:
Connect one end of yellow and green protective ground cables of switch to the ground
terminal of switch, and the other end to the wiring terminal along the grounding strip in the
machine room.
The ground wires of Ethernet switches should be connected to the machine room of switch
and grounded, and grounding connections through firefighting artery and lightning rod are
incorrect.

The normal connection of ground wires of switches is an important anti-thunder and
anti-interference guarantee of switches. Therefore, users must connect the ground wires
correctly. The ground wire connection position and grounding in the machine room shown in
the diagram are only for reference, please connect based on the actual situation of devices.
