Chapter 1 Product Overview
After the switch is powered on, the A/L LED lights up initially. If
you press the MODE button, the D/S LED lights up. After that, if you
press the MODE button again within 45 seconds, the A/L LED lights up
again, or else the A/L LED automatically lights up after 45 seconds.
The MODE button is convenient for you to check the current
status of the ports as required. For example, if you want to learn the
Duplex and the Speed status of a port, you can first press the MODE
button to switch to the D/S LED, then observe the status (OFF, ON, or
flashing) of the two LEDs beside the port, and finally determine the
current status of the port according to the above table.

Preparation
2.2 Requirements on Environment
S3100-SI series must be used indoors. When you install your
switch in a cabinet or install it directly on a workbench, you must
ensure:
z
Enough space is left near the air-intake hole and the
ventilation hole of the switch for the heat dissipation of the
switch chassis.
z
z
z
The cabinet or the workbench takes good ventilation and
heat dissipation system.
The cabinet or the workbench is solid enough to bear the
weight of the switch and the accessories.
The cabinet or the workbench is well grounded.
To ensure normal operation and to prolong the life span of the
switch, the following requirements on the installation site must also be
satisfied.
2.2.1 Temperature/Humidity Requirements
You should keep your equipment room within the proper
temperature and humidity ranges to ensure the normal operation and
working life of your switch. If the humidity in the equipment room is too
high for a long time, it may decrease the insulation attribute of
insulating material or even cause electric leakage of insulating
material, and, sometimes, may change the mechanical performance
of material and cause the rustiness and corrosion of metal parts. If the
relative humidity is too low, the captive screws may become loose due
to the shrinking of insulation washers; in addition, electrostatic is more
likely to be produced in a dry environment, which may damage the
circuit of the switch. High temperature may cause even greater

Preparation
damage to the switch. High temperature for a long time will speed up
the aging of insulation material, greatly lower the reliability of the
switch and greatly reduce the life span of the switch.
2.2.2 Cleanness Requirements
Dust is a potential hazard to the safe operation of the switch.
Falling on the equipment, it may cause electrostatic adsorption, and
hence result in poor contact of the metal connectors or connection
points. This is more likely to happen when the indoor relative humidity
is low; in this case, it may not only shorten the device’s working life,
but also incur communication failure. The requirements on dust
content and particle diameter in the equipment room are shown in the
following table:

Note: Dust particle diameter ≥ 5µm
Besides the requirements on dust, rigorous requirements are
also set on the content of chloride, acid, and sulfide in the air of the
equipment room. These kinds of harmful gas will accelerate metal
corrosion and aging of certain parts. The equipment room should be
protected from the intrusion of harmful gases such as SO2, H2S, NH3
and Cl2. The limits of these kinds of harmful gas are shown in the
following Table.

A switch in use may be affected by the interference from outside
the system by way of capacitance coupling, inductance coupling,
electromagnetic radiation, public impedance (including the grounding
system) coupling or conducting line (power line, signaling line and
transmission line etc.). Therefore, you should pay attention to the
following:
z
If AC supply system is TN system, AC power socket should
be a single-phase three-line power socket with Protection
Earth (PE) so that the filter circuit on the equipment can
effectively filter out the interference coming from the power
supply system.
z
z
z
Keep the switch far away from high-power radio transmitters,
radars, and high-frequency heavy-current devices.
Adopt electromagnetic shielding measure if necessary. For
example, you can adopt shielded interface cable.
Wire interface cables indoors. Do not wire cables outdoors
in case that overvoltage and overcurrent damage the
device.

3.3.3 Connecting Grounding wire
Caution:
You should properly connect the switch grounding wire since it is
crucial to the lightning protection and electromagnetic shield (EMS) of
your switch.
The power input end of the switch is connected with a noise filter,
whose central ground is directly connected to the chassis, forming the
so-called chassis ground (commonly known as PGND). This chassis
ground must be securely connected to the earth so that the faradism
and leakage electricity can be safely released to the earth, enhancing
the EMS capability of the switch.
Ground your switch as follows:
z
When a grounding strip is available at the installation site,
attach one end of the yellow-green grounding wire of the
switch to the grounding screw on the grounding strip and
fasten the captive nut. (Note that the fire main and lightning
rod of your building are not suitable for grounding the switch.
The grounding wire of the switch should be connected to the
construction engineering ground of the equipment room.)
