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.

Chapter 2 Installation Preparation

2.1 Precautions

To avoid any device impairment and bodily injury because of

improper use, please take the following precautions:

z Before cleaning the switch, pull out the power plug of the

switch. Do not clean the switch with wet cloth or liquid.

z Do not place the switch near water or in a damp area.

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 board, wear ESD-preventive wrist

strap to prevent the board from being damaged by

electrostatic discharge.

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 The cabinet or the workbench takes good ventilation and

heat dissipation system.

z The cabinet or the workbench is solid enough to bear the

weight of the switch and the accessories.

z 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

Quick Start
H3C S3100-SI Series Ethernet Switches

Chapter 2 Installation

Preparation

2-3

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:

Physical active

substance

Unit Content

Dust particle particle/m³

(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

2.2.3 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 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 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.

2.2.4 Laser Usage Security

S3100-SI series are category-1 laser equipment.

When an optional optical interface card of the S3100-SI 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.

Caution:

On a mounting screw of the chassis of any H3C Series Switches,

there is a seal which must be kept intact before the agent maintains

the switch for you. You must get the permission of your local agent

before you can open the chassis. Otherwise, you will be responsible

for irreversible damages caused by your operations.

3.1 Installation of the Switch

3.1.1 Mounting the Switch into a 19-Inch Cabinet

Follow these steps to mount your switch into a 19-inch standard

cabinet:

Step 1: Check the grounding and stability of the cabinet. Install a

mount ear on each side of the front panel of the switch with screws.

Caution:

Use long mount ears when installing the S3100-8T-SI or S3100-8C-SI

3.1.2 Mounting the Switch on a Workbench

When a 19-inch standard cabinet is not available, you can simply

place the switch on a clean workbench. When doing so, you should

ensure:

z The workbench is stable and well grounded.

z A clearance of about 10 cm is reserved around the switch for

heat dissipation.

z No heavy object is placed on the switch.

z The S3100-SI series are designed with no fan. Therefore,

you should install them in a drafty environment, and keep at

least 1.5 cm vertical distances between the neighboring

devices if you need to stack the switches one upon another.

3.1.3 Wall-Mount

You can hang the S3100-8T-SI and S3100-8C-SI Ethernet

Switches against walls.

I. AC power socket (recommended)

You are recommended to use a mono-phase three-wire 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.

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.)

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 wire

of the arrester is not well grounded or because the live and zero

wires 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.
