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:

2-1

Page 29

Quick Start (For Japan) H3C S3100 Series Ethernet Switches

z Enough space is reserved near the air-intake hole and the

Chapter 2 Installation Preparation

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

1.3 “Technical Specifications”.

Chapter 2 Installation Preparation

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

Dust particle particle/m³

Unit Content

≤ 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

and Cl

. The limits of these kinds of harmful gas are shown in the

, H2S, NH3

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.

z Wire interface cables indoors. Do not wire cables outdoors

in case that overvoltage and overcurrent damage the

device.

Chapter 2 Installation Preparation

2.2.4 Laser Usage Security

S3100 series are category-1 laser equipment.

When an optional optical interface card of the S3100 series is

operating, it is prohibited to stare into the optical interface because the

laser beam emitted from the optical fiber takes high energy and may

hurt your retina.

Caution:

Staring at the laser beam inside the fiber could hurt your eyes.

2.3 Installation Tools

z Phillips screwdriver

z Flat-blade screwdriver

z ESD-preventive wrist strap

Caution:

These installation tools are not shipped with S3100 series. You will

have to prepare them beforehand.

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.
