Safety recommendations
To avoid equipment damage or bodily injury, read the following safety recommendations before
installation. Note that the recommendations do not cover every possible hazardous condition.
•
Before cleaning the switch, remove all power cords from the switch. Do not clean the switch
with wet cloth or liquid.
•
Do not place the switch near water or in a damp environment. Prevent water or moisture from
entering the switch chassis.
•
Do not place the switch on an unstable case or desk. The switch might be severely damaged in
case of a fall.
•
Ensure good ventilation at the installation site and keep the air inlet and outlet vents of the
switch free of obstruction.
•
Make sure the operating voltage is as required.
•
To avoid electrical shocks, do not open the chassis while the switch is operating or when the
switch is just powered off.
•
Always wear an ESD wrist strap when installing the switch. Make sure the strap makes good
skin contact and is reliably grounded.
Examining the installation site
The switch must be used indoors. You can mount your switch in a rack or on a workbench, but make
sure of the following information:
•
Adequate clearance is reserved at the air inlet and exhaust vents for ventilation.
•
The rack or workbench has a good ventilation system.
•
Identify the cold aisle and hot aisle at the installation site, and make sure ambient air flows into
the switch from the cold aisle and exhausts to the hot aisle.
•
Identify the airflow directions of the upper and lower devices and prevent hot air exhausted from
the lower devices from flowing into the upper devices.
•
The rack is sturdy enough to support the switch and its accessories.
•
The rack or workbench is reliably grounded.
To ensure correct operation and long service life of your switch, install it in an environment that meets
the requirements described in the following subsections.
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
Hardware Information and Specifications.

1-5
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. Table1-2 describes the dust concentration limits in the
equipment room for the S5560S-SI and S5500V3-SI switch series. Table1-3 describes the dust
concentration limits in the equipment room for the S5130S-SI, S5130S-LI, S5120V2-SI, S5120V2-LI,
S5110V2-SI, S5000V3-EI, S5000V5-EI, and S3100V3-SI switch series.
Table1-2 Dust concentration limits in the equipment room (1)
Substance Particle diameter Concentration limit
Dust particles ≥ 0.5 µm ≤ 3.5 × 106particles/m3
Dust particles ≥ 5 µm ≤ 3 × 104particles/m3
Dust (suspension) ≤75 µm ≤0.2 mg/m3
Dust (sedimentation) 75 µm to 150 µm ≤1.5 mg/(m2h)
Table1-3 Dust concentration limits in the equipment room (2)
Substance Particle diameter Concentration limit
Dust particles ≥ 0.5 µm ≤ 3.5 × 106particles/m3
Dust particles ≥ 5 µm ≤ 3 × 104particles/m3
Dust (suspension) ≤75 µm ≤0.4 mg/m3
Dust (sedimentation) 75 µm to 150 µm ≤15 mg/(m2h)
Sand ≥ 150 µm ≤300 mg/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.
•
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
Corrosive gases can accelerate corrosion and aging of metal components. Make sure the corrosive
gases in the equipment room do not exceed the concentration limits as shown in Table1-4.
Table1-4 Corrosive gas concentration limits in the equipment room
Gas Average concentration (mg/m3) Maximum concentration (mg/m3)
SO20.3 1.0
H2S 0.1 0.5

1-6
Gas Average concentration (mg/m3) Maximum concentration (mg/m3)
Cl20.1 0.3
HCI 0.1 0.5
HF 0.01 0.03
NH31.0 3.0
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.
EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application
system, adversely affect the switch in the following ways:
•
A conduction pattern of capacitance coupling.
•
Inductance coupling.
•
Electromagnetic wave radiation.
•
Common impedance (including the grounding system) coupling.
To prevent EMI, use the following guidelines:
•
If AC power is used, use a single-phase three-wire power receptacle with protective earth (PE)
to filter interference from the power grid.
•
Keep the switch far away from radio transmitting stations, radar stations, and high-frequency
devices to make sure the EMI levels do not exceed the compliant range.
•
Use electromagnetic shielding when necessary. For example, use shielded interface cables.
•
To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning
strikes, only route interface cables indoors.

Attaching the mounting brackets to the switch
1. Determine the installation position for the mounting brackets.
The S5560S-28F-SI, S5560S-28DP-SI, S5500V3-28S-DP-SI, S5500V3-54S-DP-SI,
S5500V3-36F-DP-SI, S5500V3-54F-DP-SI, and S5130S-28F-SI switches each provide two
mounting positions on the two sides for mounting brackets: one front mounting position
(near the network ports) and one rear mounting position (near the power supplies).
The other switch models provide only one mounting position (near the network ports) for the
mounting brackets.
2. Align one mounting bracket with the screw holes at the mounting position. Use M4 screws to
attach the mounting bracket to the chassis. See Figure2-3 for installing mounting bracket A,
Figure2-4 and Figure2-5 for installing mounting bracket B, Figure2-6 for installing mounting

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.
If the switch is not shipped with M6 screws, prepare them yourself.
5. Verify that the switch chassis is horizontal and secure.
