Hardware Installation and Reference Guide Preparation before Installation
2.1.4 Static Discharge Damage Prevention
To prevent damage from static electricity, pay attention to the following:
Proper grounding of grounding screws on the back panel of the device. Use of a three-wire single-phase socket
with protective earth wire (PE) as the AC power socket.
Indoor dust prevention.
Proper humidity conditions.
2.1.5 Laser Safety
When a fiber transceiver works, ensure that the port has been connected with an optical fiber or is covered with a
dust cap, to keep out dust and avoid burning your eyes.
When the optical module is working, do not pull out the fiber cable and stare into the transceiver interface or you
may hurt your eyes.
Do not stare into any optical port under any circumstances, as this may cause permanent damage to your eyes.
2.2 Installation Site Requirements
To ensure the normal working and a prolonged durable life of the equipment, the installation site must meet the
following requirements.
2.2.1 Ventilation Requirements
You must ensure that sufficient space (10 cm distance from both sides and the back panel of the cabinet) is reserved at
the ventilation openings to ensure the normal ventilation. During the jumper process of the device, prevent the cables
from blocking the air intake. Dust the device every three months to avoid blocking the ventilation openings.
2.2.2 Temperature and Humidity Requirements
To ensure the normal operation and prolong the service life of the switch, you should keep proper temperature and
humidity in the equipment room.
If the equipment room has temperature and humidity that do not meet the requirements for a long time, the equipment
may be damaged.
In an environment with high relative humidity, the insulating material may have bad insulation or even leak
electricity. Sometimes the materials may suffer from mechanical performance change and metallic parts may get
rusted.
In an environment with low relative humidity, however, the insulating strip may dry and shrink. Static electricity
may occur easily and endanger the circuit on the equipment.
In an environment with high temperature, the equipment is subject to even greater harm, as its performance may
degrade significantly and various hardware faults may occur. .
Therefore, the ambient temperature and humidity must meet the requirements listed in Table 2-1:
