Chapter 2 Preparing for Installation
2.1 Safety Precautions
To avoid any device impairment and bodily injury caused by improper use, observe
these rules:
zBefore cleaning the switch, unplug the power plug of the switch first. Do not clean
the switch with wet cloth or liquid.
zDo not place the switch near water or any damp area. Prevent water or moisture
from entering the switch chassis.
zDo not place the switch on an unstable case or desk. The switch might be
damaged severely in case of a fall.
zEnsure proper ventilation of the equipment room and keep the ventilation vents of
the switch free of obstruction.
zMake sure that the operating voltage is the same one labeled on the switch.
zDo not open the chassis while the switch is operating or when electrical hazards
are present to avoid electrical shocks.
zWhen replacing interface cards, wear ESD-protective gloves to avoid damaging
the cards.
2.2 Installation Site
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:
zAdequate clearance is reserved at the air inlet/exhaust vents for ventilation.
zThe rack or table/workbench has a good ventilation system.
zThe rack is sturdy enough to support the device and its accessories.
zThe 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.
2.2.1 Temperature/Humidity
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

Installation Manual
H3C S3100-52P Ethernet Switch Chapter 2 Preparing for Installation
2-2
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”.
2.2.2 Cleanness
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:
Table 2-1 Dust content limits in an equipment room
Substance Unit Content
Dust Particles/m³
≤3 X 104
(No visible dust on the
tabletop for three days)
Remark: the diameter of a dust particle ≥5μm
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:

Installation Manual
H3C S3100-52P Ethernet Switch Chapter 2 Preparing for Installation
2-3
zFor 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.
zKeep the device far from radio transmitting stations, radar stations, and
high-frequency devices.
zUse electromagnetic shielding when necessary, for example, use shielded
interface cables.
zRoute interface cables only indoors to prevent signal ports from getting damaged
by overvoltage or overcurrent caused by lightning strikes.
2.2.4 Laser Safety
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.
2.3 Installation Tools
zFlat-blade screwdriver
zPhillips screwdriver
zESD-preventive wrist strap
Caution:
The installation tools are not provided with the S3100-52P Ethernet 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.
3.1 Installing a Switch
3.1.1 Cabinet Mounting
You can install a switch into a 19-inch standard cabinet in one of the following four
ways:
zUse front mounting ears
zUse front mounting ears and a tray
zUse front mounting ears and guide rails
Note:
Guide rails purchased from H3C apply only to standard cabinets 1,000 mm (39.4 in)
deep. Use other supports to substitute for guide rails in the case of other cabinet
depths.
