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.
The machine room had better be on the second floor or above. Otherwise, the machine room floor should be 600mm
higher than the highest flood level ever recorded.
Make sure there are no cracks or holes in the wall and floor. If there are cable entries in the wall or window, take
proper sealing measures. Ensure that the wall is flat, wear-resistant, and dust-free, which should be up to the
standard for flame retarding, soundproofing, heat absorption, dust reduction, and electromagnetic shielding.
Keep the door and the window closed to make the machine room sealed.
The steel door is recommended for soundproofing.
Sulfur-containing materials are forbidden.
Pay attention to the location of the air conditioner. Keep the air conditioner from blowing wind straight toward the
device or blowing water drops from the window or air vent toward the device.
2.2.1 Ventilation
A sufficient space (at least 10 cm distances from both sides and the back plane of the cabinet) should be reserved at the
ventilation openings to ensure the normal ventilation. After various cables have been connected, they should be arranged
into bundles or placed on the cabling rack to avoid blocking the air inlets. It is recommended to clean the switch at regular
intervals (like once every 3 months). Especially, avoid dust from blocking the screen mesh on the back of the cabinet.
2.2.2 Temperature and Humidity
To ensure the normal operation and prolong the service life of QSW-4600 series 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 of the QSW-4600 series must meet the requirements listed in Table 2-1:
