1-4
Examining the installation environment
To ensure correct operation of your switch, make sure the installation environment meets the
requirements listed in Table1-2.
Table1-2 Checking list for the installation environment
Item Requirements
Ventilation and heat dissipation
CAUTION:
To ensure correct operation of your device, make sure the installation
environment is adequately ventilated to prevent the switch from
overheating.
•Ensure a minimum clearance of 10 cm (3.94 in) around the chassis.
•Do not install the device near a heat source, for example, a stove or
heater.
•Ensure air ventilation in the installation environment.
•Do not block the ventilation holes in the device or power adapter.
Anti-moisture
CAUTION:
Water or moisture might damage the circuits of the device.
•Do not place the device near water or in a damp environment.
•Install the switch in a clean, dry, and ventilated place where
temperature is controlled in a stable range.
•Make sure
the installation environment is free from waterleakage or
condensation. If required, install a dehumidification device (such as
an air conditioner with a dehumidification function or a dedicated
dehumidifier).
•Do not operate the device under or near the water source, such as
the wash basin, laundry room, or areas with high humidity.
•Do not touch the device with wet hands.
Temperature/humidity
For correct operation and long service life of your switch, maintain the
temperature and humidity in the equipment room at acceptable ranges.
•Lasting high relative humidity can cause poor insulation, electricity
leakage, mechanical property change of materials, and metal
corrosion.
•Lasting low relative humidity can cause washer contraction and
ESD and cause issues including loose mounting screws and circuit
failure.
•High temperature can accelerate the aging of insulation materials
and significantly lower the reliability and lifespan of the switch.
For the temperature and humidity requirements of the switch, see
technical specifications in S5130S-EI Switch Series Hardware
Information and Specifications.
Lightning protection
CAUTION:
Ground the switch correctly and verify the grounding. For more
information, see "Grounding the switch."
•If you ground the switch by using a grounding strip, make sure the
grounding resistance of the grounding strip in the equipment roomis
less than 1Ω.
•If you ground the switch by using a grounding conductor buried in
the earth ground, make sure the grounding resistance of the
grounding conductor in the ground is less than 10Ω.
•Route the signal cables along indoor walls, bury the cables in the
earth ground, or thread the cables through steel tubes. Install a
signal lightning arrester with a nominal discharge current for a

1-5
Item Requirements
corresponding network interface.
•Keep the signal cables far from power cords and lightning rod down
conductors.
•As a best practice, route power cords indoors. If anAC power cord
is routed from outdoors, connect theAC power cord first to a power
lightning arrester before leading it to theAC power port on the
switch. Make sure the power lightning arrester has a nominal
discharge current and the total length of the power cord from the
power lighting arrester to the power port on the switch is less than 5
m (16.40 ft).
•
Ground the switch, rack, independent power supplies, and lightning
arresters separately.
•You must ground optical fibers with reinforcing metal stiffener from
outdoors on an optical distribution frame (ODF) or fiber splice
enclosure.
Cable routing
CAUTION:
Do not run an Ethernet cable and power cord in parallel.
•Route different types of cables separately.
•Keep power cords a minimum of 5 cm (1.97 in) away from other
cables.
ESD prevention
•Ground the switch correctly.
•To avoid ESD damage to the device or components, always wear an
ESD wrist strap when you install or remove the device or
components.
•Make sure the wrist strap has good skin contact and is reliably
grounded.
Cleanliness •For more information, see "Cleanliness."
Corrosive gas prevention The installation site must be free from corrosive gases such as acid
gases and alkaline gases. For more information, see "Corrosive gas
limit."
EMI
•If AC power is used, use a single-phase three-wire power receptacle
with protection earth (PE) to filter interference from the power grid.
•Keep the device far away from radio transmitting stations, radar
stations, and high-frequency devices.
•Use electromagnetic shielding, for example, shielded interface
cables, when necessary.
Cleanliness
Dust buildup on the chassis might cause electrostatic adsorption and dust corrosion, resulting in
poor contact of metal connectors and contact points. This might shorten the device's lifetime and
even cause device failure in the worst case. Table1-3 describes the switch requirement for
cleanliness.
Table1-3 Switch requirement for cleanliness
Substance Particle diameter Concentration limit
Dust particles ≥ 0.5 µm ≤ 1.8 × 107particles/m3
To maintain cleanliness in the equipment room, follow these guidelines:
•
Keep the equipment room away from pollution sources. Do not smoke, eat, or drink in the
equipment room.

1-6
•
Use double-layer glass in windows and seal doors and windows with dust-proof rubber strips.
Use screen doors and window screens for doors and windows open to the outside and make
sure the external windows are air tight.
•
Use dustproof materials for floors, walls, and ceilings and use wallpaper or matt paint that does
not produce powders.
•
Clean the equipment room regularly and clean the air filters of the rack each month.
•
Wear ESD clothing and shoe covers before entering the equipment room, keep the ESD
clothing and shoe covers clean, and change them frequently.
Corrosive gas limit

O30.05 0.1
NOX0.5 1.0
CAUTION:
As a best practice, control the
corrosive gas concentrations in the equipment room at their
average
values
. Make sure the corrosive gas concentrations do not exceed 30 minutes per day at their
maximum values.
To control corrosive gases, use the following guidelines:
•
As a best practice, do not build the equipment room in a place with a high concentration of
corrosive gases.
•
Make sure the equipment room is not connected to sewer, vertical shaft, or septic tank pipelines
and keep it far away from these pipelines. The air inlet of the equipment room must be away
from such pollution sources.
•
Use environmentally friendly materials to decorate the equipment room. Avoid using organic
materials that contains harmful gases, such as sulfur or chlorine-containing insulation cottons,
rubber mats, sound-proof cottons, and avoid using plasterboards with high sulfur concentration.
•
Place fuel (diesel or gasoline) engines separately. Do not place them in the same equipment
room with the device. Make sure the exhausted air of the engines will not flow into the
equipment room or towards the air inlet of the air conditioners.
•
Place batteries separately. Do not place them in the same room with the device.
•
Employ a professional company to monitor and control corrosive gases in the equipment room
regularly.

Rack-mounting the switch
This task requires two people. To mount the switch in the rack:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Verify that the mounting brackets have been securely attached to the switch chassis.
3. Install cage nuts in the mounting holes in the rack posts.
No cage nuts are provided with the switch. Prepare them yourself.
4. One person holds the switch chassis and aligns the mounting brackets with the mounting holes
in the rack posts, and the other person attaches the mounting brackets to the rack with M6
screws.
M6 screws are provided only for switches shipped with mounting brackets. For switches not
shipped with mounting brackets, prepare M6 screws yourself.
5. Verify that the switch chassis is horizontal and secure.

Mounting the switch on a workbench
IMPORTANT:
•
Ensure 10 cm (3.9 in) of clearance around the chassis for heat dissipation.
•Do not place heavy objects on the switch.
If a standard 19-inch rack is not available, you can place you switch on a workbench.
To mount the switch on a workbench:
1. Verify that the workbench is sturdy and reliably grounded.
2. Place the switch with bottom up, and clean the round holes in the chassis bottom with dry cloth.
3. Attach the rubber feet to the four round holes in the chassis bottom.
4. Place the switch with upside up on the workbench.

Grounding the switch
WARNING
!
Correctly
connecting the switch grounding cable is crucial to lightning protection, ESD, and EMI
protection.
For information about lightning protection, see H3C Network Devices Lightning
Protection Guide.
To protect against the following types of issues, use a grounding cable to connect the switch to the
earthing facility at the installation site:
•
Bodily injury from electric shocks.
•
Device and power and data line damages.
•
Electrical fires, lightning strokes, electromagnetic coupling interferences, and ESD damages.
You can ground the switch in one of the following ways, depending on the grounding conditions
available at the installation site:
•
Grounding the switch with a grounding strip
•
Grounding the switch with a grounding conductor buried in the earth ground
NOTE:
The
chassis views and power supply and grounding terminal positions in the following figures
are for
illustration only.
Grounding the switch with a grounding strip
WARNING
!
Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a
fire main or lightning rod.
The grounding screw and grounding hole (with a grounding sign) are located at the rear panel of the
switch.
To ground the switch by using a grounding strip:
1. Attach the ring terminal end of the grounding cable to the grounding hole in the switch.
a. Remove the grounding screw from the grounding hole in the rear panel of the switch.
b. Attach the grounding screw to the ring terminal of the grounding cable.
c. Use a screwdriver to fasten the grounding screw into the grounding hole.
