Safety recommendations
To avoid any equipment damage or bodily injury caused by improper use, 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 of the equipment room and keep the air inlet and outlet vents of the
switch free of obstruction.
•
Make sure the power input voltage is as required by the power supply.
•
To avoid electrical shocks, do not open the chassis while the switch is operating or when the
switch is just powered off.
•
During switch installation, wear an ESD wrist strap. Make sure the strap makes good skin
contact and is reliably grounded.
Examining the installation site
The switchmust be used indoors. You can mount your switch in a rack or on a workbench. Make sure
the following requirements are met:
•
Adequate clearance is reserved at the air inlet and outlet vents for ventilation.
•
The rack or workbench has a good ventilation system.
•
Identify the hot aisle and cold aisle at the installation site, and make sure ambient air flows into
the switch from the cold aisle and exhausts to the hot aisle.

1-2
•
Identify the airflow designs of neighboring devices, and prevent hot air flowing out of the
neighboring device from entering the device.
•
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.
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. Table1-1 describes the dust concentration limits in the
equipment room.
Table1-1 Dust concentration limits in the equipment room
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)
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.

1-3
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 Table1-2.
Table1-2 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
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:

1-4
•
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 switch far away from radio transmitting stations, radar stations, and high-frequency
devices.
•
Use electromagnetic shielding, for example, shielded interface cables, when necessary.
•
To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning
strikes, route interface cables only indoors.
