The network cabinet is used to combine installation panels, plug-ins, sub-boxes, electronic components, devices and mechanical parts and components to form a whole installation box.
According to the type, there are server cabinets, wall-mounted cabinets, network cabinets, standard cabinets, intelligent protective outdoor cabinets, etc. The capacity value is between 2U and 42U.
Cabinet Features:
· Simple structure, convenient operation and installation, exquisite workmanship, precise size, economical and practical;
· Internationally popular white tempered glass front door;
· Upper frame with circular ventilation holes;
· Casters and support feet can be installed at the same time;
· Detachable left and right side doors and front and rear doors;
· Full range of optional accessories.
The network cabinet is composed of a frame and a cover (door), and generally has a rectangular parallelepiped shape and is placed on the floor. It provides suitable environment and safety protection for the normal operation of electronic equipment. This is the level of assembly second only to the system level. A cabinet without a closed structure is called a rack.
The network cabinet should have good technical performance. The structure of the cabinet should carry out necessary physical design and chemical design according to the electrical and mechanical properties of the equipment and the requirements of the use environment, so as to ensure that the structure of the cabinet has good rigidity and strength, as well as good electromagnetic isolation, grounding, noise isolation, ventilation and heat dissipation and other performance. In addition, the network cabinet should have anti-vibration, anti-shock, corrosion-resistant, dust-proof, waterproof, radiation-proof and other properties, so as to ensure the stable and reliable operation of the equipment. The network cabinet should have good usability and safety protection facilities, which is easy to operate, install and maintain, and can ensure the safety of the operator. The network cabinet should be convenient for production, assembly, commissioning, packaging and transportation. Network cabinets should meet the requirements of standardization, standardization, and serialization. The cabinet is beautiful in shape, applicable and coordinated in color.
Cabinet finishing:
1. Preliminary preparation
First of all, the user should be notified to organize the cabinet without affecting the normal work of the user.
Then draw out the wiring diagram and equipment location diagram inside the cabinet according to various factors such as network topology, existing equipment, number of users, and user grouping.
Next, prepare the required materials: network jumpers, label paper, and various types of plastic cable ties (strangle the dog).
2. Organize the cabinet
Install the cabinet:
You need to do the following three things by yourself: first, use the screws and nuts that come with the frame to tighten the fixing frame; second, knock down the cabinet and install the movable wheels; third, according to the location of the equipment Adjust and add baffles to the mount.
Organize lines:
Group the network cables, and the number of groups is usually less than or equal to the number of cable management racks behind the cabinet. Bundle the power cords of all devices together, insert the plugs from the rear through hole, and find the respective devices through a separate cable management frame.
Fixed equipment:
Adjust the baffles in the cabinet to a proper position, so that the administrator can see the operation of all the equipment without opening the cabinet door, and add baffles appropriately according to the number and size of the equipment. Be careful to leave some space between the baffles. Place all the switching equipment and routing equipment used in the cabinet according to the pre-drawn diagram.
Cable labeling:
After all the network cables are connected, it is necessary to mark each network cable, wrap the prepared post-it note on the network cable, and mark it with a pen (generally indicate the room number or what it is used for), and the label is required to be simple and easy to understand. Crossover network cables can be distinguished from ordinary network cables by using sticky notes of different colors. If there are too many devices, the devices should be classified and numbered, and the devices should be labeled.
3. Post work
UMC test:
After confirming that it is correct, turn on the power and conduct a network connection test to ensure the normal work of the user – this is the most important thing.
