Cut off all the power supplies and unplug all power cords before moving or handling the switch.
2.1.3 Electric Safety
Observe local regulations and specifications during 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.
Find out the position of the indoor emergency power switch before installation. Cut off the power switch in case of accidents.
Do not maintain the device by yourself when the device is powered on.
Make sure that the device is powered off when you cut off the power supply.
Do not place the switch in a wet position, and keep the switch away from liquid.
Any nonstandard and inaccurate operation can cause an accident such as fire or electrical attack, thus causing severe damages
to human bodies and device.
Direct or indirect touch through a wet object on high-voltage and mains supply can bring a fatal danger.
If a power supply system is equipped with a leakage protector (also referred to as “leakage current switch” or “leakage current
breaker”), 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 with 16 identical power supplies, the leakage
current of each power supply is equal to or less than 1.75 mA, and the leakage current of the system totals 28 mA. A leakage
protector with 30 mA rated action current supports less than nine power supplies (that is, Action current of the leakage
protector/2/Maximum leakage current of each power supply = 30/2/1.75 ≈ 8.57). In other words, the leakage protector with 30

15
mA rated action current supports no more than eight power supplies. In this case, the 16 power supplies in the system require at
least two leakage protectors with 30 mA rated action current and each leakage protector supports eight 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. Otherwise,
misoperation may easily occur due to high sensitivity and thus the leakage protector trips, devices are powered off, and services
are interrupted.
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 of each power supply model, see the power supply model specifications in Chapter 1.
2.1.4 Electrostatic Discharge Safety
To prevent damage from static electricity, you must pay attention to the following:
Properly ground the device and floor.
Keep the indoor installation environment clean and free of dust.
Maintain appropriate humidity conditions.
2.1.5 Laser Safety
Among the modules supported by the switch, there are many transceiver modules that are Class I laser products.
When a fiber transceiver works, ensure that the port has been connected with a fiber or covered by a dust cap to keep out dust
and prevent it from burning your eyes.
Do not stare at any fiber port.
2.2 Installation Environment Requirements
Install the switch indoors to ensure its normal operation and prolonged service life. The installation site must meet the following
requirements.
2.2.1 Ventilation Requirements
Maintain a minimum clearance of 100 mm (3.94 in.) around the device for air circulation. After various cables are connected, bundle
the cables or place them in the cable management bracket to avoid blocking air inlets.
2.2.2 Temperature/Humidity Requirements
To ensure the normal operation and prolonged service life of the switch, 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 damage the switch.
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, static electricity is prone to occur and damage the internal circuits of the switch.

Too high temperatures can accelerate the aging of insulation materials, greatly reducing the reliability of the switch and severely
affecting its service life.
Temperature and Humidity

The ambient temperature and humidity of the switch 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 switch rack when there is no protective plate in front or at the back of the rack
2.2.3 Cleanliness Requirements
Dust poses a major threat to the switch. The indoor dust takes on a positive or negative static electric charge when falling on the switch,
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 switch, but also causing communication faults. The following table describes the requirements for
the dust content and granularity in the equipment room.

Apart from dust, the salt, acid, and sulfide in the air in the equipment room must meet strict requirements. These harmful substances
will accelerate metal corrosion and component aging. Therefore, the equipment room should be properly protected against the
intrusion of harmful gases, such as sulfur dioxide, hydrogen sulfide, nitrogen dioxide, and chlorine gas.

The Average refers to the average limit of harmful gas in one week. The Maximum value is the upper limit of the harmful gas
measured in one week for up to 30 minutes every day.
2.2.4 Anti-interference Requirements
The AP is susceptible to external interference by capacitive coupling, inductive coupling, electromagnetic waves, common impedance
(ground) coupling, or conduction over power lines, signal lines and output lines. Note that:
In a TN earthing system, use a 3-wire single-phase outlet that has a protective earth (PE) contact to allow the filter circuit in the
device to eliminate interference from the power grid.
The switch should be located far away from the large power radio launch pad, radar launch pad, and high-frequency large-current
devices.
Use EMI shielding such as shielded interface cables to minimize interference when necessary.
Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or overcurrent caused by
lightning strikes.
