2.1.4 ESD
To prevent Electronic Static Discharge (ESD), pay attention to the following:
Connect the device's circuit to the ground.
Clear up the dust.
Maintain the proper humidity.
2.1.5 Laser
Among the modules supported by the QSW-6200 series, many are Class I laser products. Therefore, pay attention to the
following when using them:
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.
Do not stare into the optical ports.
Do not approach or stare into any optical port, as this may cause permanent damage to your eyes.
2.2 Installation Site Requirements
The QSW-6200 series must be used indoors. To ensure its functioning and prolong its service life, the installation site
must meet the following requirements.
The machine room should be at least 5km away from the heavy pollution source such as the smelter, coal mine
and thermal power plant, 3.7km away from the medium pollution source such as the chemical industry, rubber
industry and electroplating industry, and 2km away from the light pollution source such as the food manufacturer
and leather plant. If the pollution source is unavoidable, the machine room should be located on the windward
side of the pollution source perennially with advanced protection.
The machine room should be at least 3.7km away from the sea or salt lake. Otherwise, the machine room must
be sealed, with air conditioner installed for temperature control. Saline soil cannot be used for construction.
Otherwise, you should select devices with advanced protection against severe environment.
Do not build the machine room in the proximity of livestock farms. Otherwise, the machine room should be
located on the windward side of the pollution source perennially. The previous livestock house or fertilizer
warehouse cannot be used as the machine room.
The machine room should be firm enough to withstand severe weather conditions such as windstorm and heavy
rain as well as away from dust. If the dust is unavoidable, keep the door and window away from the pollution
source.
The machine room should be away from the residential area. Otherwise, the machine room should meet the
construction standard in terms of noise.
Make sure the air vent of the machine room is away from the sewage pipe, septic tank, and sewage treatment
tank. Keep the machine room under positive pressure to prevent corrosive gas from entering the machine room
to corrode components and circuit boards. Keep the machine room away from industrial boiler and heating boiler.
