2 Preparing for Installation
2.1 Safety Precautions
Note
●To avoid device damage and physical injury, please read the safety precautions carefully before installing
the device.
●The following safety precautions may not cover all possible dangers.
2.1.1 General Safety Precautions
Install the device in a standard 19-inch cabinet.
Do not place the device in a wet position, and keep the device away from liquid. Keep the chassis clean and
dust-free.
Place the device away from heat sources.
Make sure that the cabinet and the power distribution system are properly grounded.
Do not place the device in walking areas.
Do not wear loose clothes, ornaments, or other items that may be hooked by the chassis during installation
and maintenance.
Keep the tools and components away from walking areas.
2.1.2 Handling Safety
Avoid handling the device frequently after installation.
Cut off all power supplies and unplug all power cords before moving and handling the device.
Do not handle the device alone. At least two persons are needed. Keep balance and prevent personal injuries
when handling the device.
2.1.3 Electric Safety
Warning
●Improper or incorrect electric operations may cause a fire, electric shock, and other accidents, and lead to
severe and fatal personal injury and device damage.
●Direct or indirect contact with high voltage or mains supply through wet objects may cause fatal dangers.
Observe local rules and regulations when performing electric operations. Only personnel with relevant
qualifications can perform such operations.
Check whether there are potential risks in the work area. For example, check whether the power supply is
grounded, whether the grounding is reliable, and whether the ground is wet.
Learn about the position of the indoor emergency power switch before installation. Cut off the power switch
in case of accidents.

Hardware Installation and Reference Guide Preparing for Installation
8
Check the device carefully before shutting down the power supply.
Select a correct leakage protector (also referred to as “leakage current switch” or “leakage current breaker”)
for the power supply system. When there is a risk of leakage and electric shock, the power supply is
automatically disconnected. A correct leakage protector should meet the following requirements:
○The rated leakage action current of each leakage protector is greater than twice of the theoretical
maximum leakage current of all the power supplies in the system. For example, if a system is equipped
with16 identical power supplies, the leakage current of each power supply is equal to or less than 3.5
mA, and the leakage current of the system totals 56 mA. A leakage protector with 30 mA rated action
current supports less than five power supplies (that is, Actioncurrent of the leakage protector/2/Maximum
leakage current of each power supply = 30/2/3 .5 ≈4.28). In other words, the leakage protector with 30
mA rated action current supports no more than four power supplies. In this case, the 16 power supplies
in the system require at least four leakage protectors with 30 mA rated action current and each leakage
protector supports four power supplies.
If power supplies in a system differ in models, the rated leakage action current of each leakage protector
divided by two is greater than the sum of maximum leakage currents of all the power supplies.
○The rated leakage non-action current of a leakage protector shall be 50% of the leakage action current.
Take a leakage protector with 30 mA rated leakage action current as an example. The rated leakage
non-action current shall be 15 mA. When the leakage current is below 15 mA, the protector shall not act.
Caution
To guarantee personal safety, the rated leakage action current of each leakage protector in the system must be
equal to or less than 30 mA (human body safety current is 30 mA). When twice of the total leakage current of
the system is greater than 30 mA, the system must be equipped with two or more leakage protectors.
For the leakage current value, see Section 1.3 Technical Specifications.
2.1.4 Electrostatic Discharge Safety
Ensure that the device is properly grounded.
Keep the indoor installation environment free of dust.
Maintain proper humidity conditions in the installation environment.
Before installing various pluggable modules, please wear an anti-static wrist strap and ensure that the anti-
static wrist strip is properly grounded.
2.2 Installation Environment Requirements
The device must be installed indoors. To ensure its normal operation and prolonged service life, the installation
site must meet the following requirements.
2.2.1 Bearing Requirements
Evaluate the weight of the switch and its accessories (for example, the cabinet, chassis, and power supply
modules), and ensure that the ground of the installation site meets the requirements.

Hardware Installation and Reference Guide Preparing for Installation
9
2.2.2 Ventilation Requirements
Maintain a proper clearance around the device for air circulation and normal heat dissipation. After various
cables are connected, bundle the cables or place them in the cable management bracket to avoid blocking air
inlets.
2.2.3 Space Requirements
It is recommended that the width of the equipment room corridor be greater than 0.8 m (31.50 in.) to ensure
enough space for chassis handling and module maintenance.
Please do not install the device against the wall. Instead, maintain a minimum clearance of 0.4 m (15.75 in.)
around the device for heat dissipation and device maintenance.
2.2.4 Temperature/Humidity Requirements
To ensure the normal operation and prolonged service life of the device, maintain an appropriate temperature
and humidity in the equipment room.
The equipment room with too high or too low temperature and humidity for a long period may cause damage to
the device.
In an environment with high relative humidity, the insulating material may have poor insulation or even leak
electricity.
In an environment with low relative humidity, the insulating strip may dry and shrink, loosening screws.
In a dry environment, static electricity is prone to occur and damage the internal circuits of the device.
Too high temperatures can accelerate the aging of insulation materials, greatly reducing the reliability of the
device and severely affecting its service life.
Note
The ambient temperature and humidity of the device are measured at the point that is 1.5 m (59.06 in.) above
the floor and 0.4 m (15.75 in.) before the device rack when there is no protective plate in front or at the back of
the rack.
2.2.5 Cleanliness Requirements
Dust poses a major threat to the device. The indoor dust takes on a positive or negative static electric charge
when falling on the device, causing poor contact of the metallic joint. Such electrostatic adhesion may occur
more easily when the relative humidity is low, not only affecting the service life of the device, but also causing
communication faults. The following table describes the requirements for the dust content and granularity in the
server room.

2.2.6 Grounding Requirements
A proper grounding system is the basis for stable and reliable running and is indispensable for preventing
lightning strikes and interference. Carefully check the grounding conditions at the installation site according to
the grounding specifications, and complete grounding properly based on the actual situation.
Safety Grounding
Ensure that the cabinet and power distribution device are properly grounded when the device uses the AC
power supply. Otherwise, electric shockmay occur when the insulation resistance between the power supply
inside the device and the chassis becomes small.
Caution
Please adopt protection grounding connections in buildings so that the device can be connected to the protection
ground.
Check whether the AC socket is reliably connected to the protection ground of the building. If not, a protection
ground wire should be used to connect the protection ground lug of the AC socket to the protection ground of
the building.
The cross-sectional area of the protection ground cable should be at least 0.75 mm2(18 AWG).
Lightning Grounding
The lightning protection system of facilities is standalone, and is composed of a lightning rod, a lower
conductor, and a connector connected to the grounding system. The grounding system is usually used for
power reference grounding and safety grounding of the cabinet. Lightning grounding is required only for
facilities and is not required for the device.
EMC Grounding

Hardware Installation and Reference Guide Preparing for Installation
11
Grounding required for electromagnetic compatibility (EMC) includes shielded grounding, filter grounding,
noise and interference suppression, and level reference, which contribute to the overall grounding
requirements. The grounding resistance should be less than 1 ohm, and the grounding lugs of the cabinet
should be grounded before the running of the device.
2.2.7 Anti-interference Requirements
Take interference prevention measures for the power supply system.
Keep the device away from the grounding equipment or lightning and grounding equipment of the power
device as much as possible.
Keep the device far away from high-frequency current devices such as high-power radio transmitting station
and radar transmitting station.
Take electromagnetic shielding measures when necessary.
2.2.8 Lightning Protection Requirements
The device can guard against lightning strikes. As an electric device, it may still be damaged by strong lightning
strikes. Take the following lightning protection measures:
Ensure that the grounding cable of the rack is in good contact with the ground.
Ensure that the neutral point of the AC power socket is in good contact with the ground.
You are advised to install a power lightning arrester in front of the power input end to enhance the lightning
prevention for the power supply.
2.2.9 Installation Site Requirement
Regardless of whether the device is installed into a rack or on a workbench, the following conditions must be
met:
Maintain a proper clearance around the air inlets and ventilation openings for heat dissipation.
The device is equipped with two cooling fans. Cold air is drawn through the ventilation openings around the
chassis and exhausted from the rear of the chassis through the fans. Thus, maintain a minimum clearance
of 15 cm (5.90 in.) around the device to ensure normal heat dissipation. You are advised to install the device
in a standard 19-inch rack. If not, you can place the device on a clean workbench. If the installation area is
hot, air conditioning is recommended.
Ensure that the rack and workbench have proper ventilation and heat dissipation.
Ensure that the rack and workbench are sturdy enough to support the weight of the device and its accessories.
Ensure that the rack and workbench are properly grounded.
