Five Basic Knowledge To Know The Network Rack Cabinet

Five Basic Knowledge To Know The Network Rack Cabinet

With the continuous development of network technology and integrated wiring technology, network communication equipment, data center servers and other IT facilities are developing towards racking, networking, and miniaturization. Therefore, the status of cabinets has evolved into a very The important role, take you to learn the basic knowledge of the cabinet today.

First, the classification of the cabinet

Extended classification: console, monitoring console, tool cabinet, standard cabinet, network cabinet, computer cabinet cabinet, stainless steel cabinet.

According to the scope of application: power cabinets, server cabinets, indoor cabinets, communication cabinets, outdoor cabinets, industrial safety cabinets, low-voltage power distribution cabinets.

Divided by function: fireproof antimagnetic cabinet, safety cabinet, waterproof cabinet, safe, multimedia console, file cabinet, wall cabinet, power cabinet, monitoring cabinet, shielding cabinet.

Second, the concept of capacity "U"

The height of the equipment installation in the 19-inch standard cabinet cabinet is represented by a special unit "U". U refers to the effective internal space of the cabinet, 1U=44.45mm. That is, how many U of 19-inch standard equipment can be installed, and the panel of standard equipment using 19-inch standard cabinets is generally manufactured according to the specification of n U.

Third, the difference between racks and cabinets

They are used to place 19-inch equipment, the load capacity of the 4-post rack is greater than the 2-post rack, the 2-post rack accessories are cantilevered, fixed at 2 points, and the 4-post rack accessories are installed in the same way as the cabinet, 4 points fixed , And the cabinet is closed, which is conducive to the protection of internal equipment; but the rack is open, there are no doors at the front, back, left, and right to facilitate the installation and construction of related equipment, but the dustproofness is relatively poor. Compared with the cabinet, the external environment requires more Higher.

Fourth, the difference between network cabinets and server cabinets

There are requirements on the depth, height, and load bearing of the cabinet. The width is generally 600MM, and the depth is generally more than 900MM. Due to the large heat dissipation of the internal equipment, the front and rear doors are provided with ventilation holes. The power cabinet cabinet and the server cabinet cabinet are 19 inches. Standard cabinets, server cabinets are used to install servers, monitors, UPS and other 19 "standard equipment and non-19" standard equipment.

The network cabinet is mainly used to store network equipment and accessories such as routers, switches, and distribution frames. The depth is generally less than 800MM, and the width is 600 and 800MM. The front door is generally a transparent tempered glass door, which has low requirements for heat dissipation and environment.

Fifth, the concept of grounding

Grounding includes signal grounding and chassis grounding. The signal grounding function of the equipment is to provide the level reference plane of some or all circuits of the equipment. The ideal grounding plane is a physical entity with zero potential and zero impedance. Any current passes through it. There will be no voltage drop at all times, and the signal ground is usually realized by a dedicated grounding copper bar;

The earth connection of the bushing is to realize the safety earthing of the equipment, prevent electric leakage, and realize the safety protection of the operator.
