Chapter 2 Preparing for Installation
To avoid any device impairment and bodily
injury caused by improper use, observe these rules:
l
Before cleaning the switch, unplug the power
plug of the switch first. Do not clean the switch with wet cloth or liquid.
l
Do not place the switch near water or any damp
area. Prevent water or moisture from entering the switch chassis.
l
Do not place the switch on an unstable case or
desk. The switch might be damaged severely in case of a fall.
l
Ensure proper ventilation of the equipment room
and keep the ventilation vents of the switch free of obstruction.
l
Make sure that the operating voltage is the same
one labeled on the switch.
l
Do not open the chassis while the switch is
operating or when electrical hazards are present to avoid electrical shocks.
l
When replacing interface cards, wear
ESD-protective gloves to avoid damaging the cards.
The S3100-52P Ethernet switch must be used
indoors. You can mount your switch in a rack or on a tabletop/workbench, but
make sure:
l
Adequate clearance is reserved at the air
inlet/exhaust vents for ventilation.
l
The rack or table/workbench has a good ventilation
system.
l
The rack is sturdy enough to support the device
and its accessories.
l
The rack or table/workbench is well earthed.
To ensure normal operation and long service
life of your VG, install it in an environment that meets the requirements
described in the following subsections.
You must maintain a proper temperature and
humidity in the equipment room. Long-term high humidity may lead to bad
insulation, electricity leakage, mechanical property changes, and corrosion. However,
if the relative humidity is two low, captive screws may become loose as the
result of contraction of insulation washers and static electricity may be
produced in a dry environment to jeopardize the CMOS circuits on the device.
High temperature is the most undesirable condition, because it accelerates
aging of insulation materials and can thus significantly lower reliability and
service life of your switch.
For the temperature/humidity requirement on
the S3100-52P switch, refer to section 1.3 “System Features of the S3100-52P Ethernet Switch”.
Dust is a hazard to the operating safety of
your device. The dust accumulated on the chassis can be adsorbed by static
electricity and result in poor contact of metal connectors or metal contact
points. This can not only shorten the service life of your device but also
cause communications failures. When the relative indoor humidity is low,
electrostatic adsorption is more likely to happen. The contents of the dust
must be limited as shown in Table 2-1:

Besides dust, there are rigorous limits on
the harmful gases that can accelerate the erosion and aging of metals, such as
salts, acids, and sulfides, as shown in Table 2-2.

2.2.3 Electromagnetic Susceptibility
The operation of your switch can be
affected by external interferences, such as conducted emission by capacitance
coupling, inductance coupling, electromagnetic wave radiation, and common
impedance (including the grounding system) coupling, and leads (power cords,
signaling cables and output wires. To eliminate the interferences, make sure
to:
l
For the AC power supply that adopts TN system,
use a monophase three-line power socket with Protection Earth (PE) to
effectively filter interference from the power grid.
l
Keep the device far from radio transmitting stations,
radar stations, and high-frequency devices.
l
Use electromagnetic shielding when necessary,
for example, use shielded interface cables.
l
Route interface cables only indoors to prevent
signal ports from getting damaged by overvoltage or overcurrent caused by
lightning strikes.
The S3100-52P Ethernet switch is a class-1
laser device.
If the extended optical modules on your
switch are operating, do not stare into the optical ports because the laser
light emitted by the optical fiber can hurt your retina.
Caution:
Staring into the
laser beam produced by the fiber can hurt your eyes.

Chapter 3 Installing the Switch
Caution:
When you ask your
sales agent to maintain the switch, you must ensure that the
dismantlement-preventive seal on a mounting screw of the switch chassis is
intact. If you want to open the chassis, you should contact the agent for
permission. Otherwise, you will bear any consequence resulted from your actions
without permission.
You can install a switch into a 19-inch
standard cabinet in one of the following four ways:
l

inches) between devices for the purpose of heat dissipation.
When placing the switch on a tabletop or
workbench, you simply need to:
l
Make sure that the tabletop or workbench is
clean, flat, and sturdy.
l
Allow 10 cm (3.9 in.) of clearance around the
sides of the chassis.
l
Do not place heavy objects on the switch.
3.2.1 Connecting the AC-Input Power Cord
I. AC-input power socket
(recommended)
You are recommended to use a monophase
three-line power socket with a ground contact or a general purpose PC power
socket, making sure that the power point is well connected to building ground.
Normally, the ground point of the power source in a building was buried in the
ground during the construction and wiring. Still, you must make sure of that.
Figure 3-8 Power
socket (recommended)
II. Connecting the AC-input power
cord
Step 1: Connect one end of the chassis
ground wire to the grounding screw on the rear of the chassis and the other end
to the ground as near as possible.
Step 2: Connect one end of the power cord
to the power socket on the rear of the chassis, and plug the other end to the
AC power jack of the power source.
Step 3: Check that the PWR LED on the front
panel of the switch is ON.
Caution:
Before powering on
the switch, connect the ground wire.
Caution:
Correctly
connecting the switch ground wire is crucial to the lightning protection and
electromagnetic susceptibility (EMS) of a 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 chassis ground (commonly known
as PGND). This chassis ground must be securely connected to the earth ground so
that the faradism and leakage electricity can be safely released to the ground,
enhancing the EMS capability of the switch.
Ground your switch as follows:
l
When a grounding strip is available at the
installation site, attach one end of the yellow/green ground 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 a building are not suitable for
grounding the switch. The ground wire of the switch should be connected to the
grounding device for the equipment room.)

|
(3): Ground wire
|
(4): Grounding strip
|
Figure 3-9 Grounding the switch through
a grounding strip
l
When there is no grounding strip but earth near
the equipment room that allows a grounding body to be buried, hammer an angle
iron/steel pipe longer than 0.5 m into the earth, weld the yellow-green ground
wire of the switch onto the angle iron/steel pipe, and process the joint
against erosion.
