Chapter 2 Installation Preparation
2.1 Precautions
To avoid any device impairment and body injury resulting from
improper use, please take the following precautions:
z Before cleaning the switch, disconnect the power. Do not
clean the switch with wet cloth or liquid.
z Keep the switch away from water or dampness. Prevent
water or moisture from entering the switch chassis.
z Do not place the switch on an unstable case or desk,
because the switch might be damaged severely in case of a
fall.
z Keep the switch room drafty and the switch ventilation hole
free of obstruction.
z The switch can operate normally only under correct voltage
input. Make sure that the operating voltage is consistent with
that labeled on the switch.
z To prevent electric shock, do not open the chassis while the
switch is operating, and do not open the chassis arbitrarily
even when the switch is powered off.
z Before changing interface cards, wear an ESD-preventive
wrist strap to prevent the cards from being damaged by
electrostatic discharge.
2.2 Requirements on Environment
S3100 Series Ethernet Switches must be used indoors. When
you install your switch in a cabinet or on a desk, you must ensure:
Page 23
Quick Start (For Soliton)
H3C S3100 Series Ethernet Switches
Chapter 2 Installation Preparation
2-2
z Enough space is reserved near the air-intake hole and the
ventilation hole of the switch for heat dissipation of the
switch chassis.
z The cabinet or the workbench takes good ventilation and
heat dissipation system.
z The cabinet or the desk is solid enough to bear the weight of
the switch and the accessories.
z The cabinet or the desk 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
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.
For the temperature and humidity requirements of different
models, refer to section
1.4 “Technical Specifications”.

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.

Physical active
substance
Unit Content
Dust particle particle/m³
≤ 3 x 10

(No visible dust
on desk in three days)
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 SO
2
, H2S, NH3
and Cl
2
. The limits of these kinds of harmful gas are shown in the
following Table.

2.2.3 Anti-interference Requirements
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). 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 Keep the switch far away from high-power radio transmitters,
radars, and high-frequency heavy-current devices.
z Adopt electromagnetic shielding measure if necessary. For
example, you can adopt shielded interface cable.

3.2.1 Connecting AC Power Cord
I. AC power socket (recommended)
You are recommended to use a mono-phase three-core power
socket with a neutral point or a multi-function power socket for
computers. The neutral point of the power in your building must be
well grounded. Normally, the neutral point of the power supply system
in your building has already been grounded during the construction
and wiring; but you should make sure this is the fact.
Figure 3-13 Recommended AC power socket
II. Connecting AC power cord
1) Connect one end of the chassis grounding cable (coming
with the switch) to the grounding screw on the rear of the
chassis and the other end to the ground nearby.
2) Connect one end of the power cord to the power socket on
the rear panel of the chassis and the other end to an outside
AC power socket.

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 cable 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.

Caution:
z Make sure that the arrester is well grounded before using the
lightning arrester for power.
z After inserting AC power cord plug of switch into the socket of
lightning arrester, if the green LED is on and the red LED does not
alarm, it means that the lightning arrester of power is running and
the function of lightning protection has taken effect.
z Pay adequate attention if the red LED is on. You should correctly
locate the problem, whether it is caused because the ground cable
of the arrester is not well grounded or because the live and zero
cables are connected in reverse direction. You may check that in
the following way. When the red LED is on, use a multimeter to
examine polarity at the power socket of the arrester. If it is same to
that of the power socket in the equipment room, it means that
arrester is not well grounded. If it is adverse to that of the power
socket in the equipment room, it means that the power socket of
the arrester is set to the reverse polarity. In this case, you should
open the power socket of arrester to correct polarity. After that, if
the red LED still alarms, it means that the arrester is not well
grounded yet.

III. Installation precautions
Fully consider the following items in the installation process,
otherwise, the performance of the lightning arrester for network port
will be affected:
z Lightning arrester for network port is installed in reverse
direction. In practice, the “IN” end should be connected to
the outdoor network cable and the “OUT” end to the network
port on the switch.
z Lightning arrester for the network port is not well grounded.
The ground cable for the arrester should be as short as
possible, so to ensure its good contact with the grounding
screw of the switch. After the connection, use the multimeter
to confirm that.
