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
The QSW-4600 series switch supports varying models of optical modules sold on the market which are Class I laser
products. Improper use of optical modules may cause damage. Therefore, pay attention to the following when you use
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.
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.
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.
