Cabinet Strategy for Integrated Wiring

With the development of computer and network technologies, servers, network communication equipment and other IT equipment are moving towards miniaturization, networking, and rack-based Development. The demands for Cabinet Management in data centers will grow. A cabinet or rack is no longer a container used to hold servers or other devices, but is no longer a low-value or ancillary product in IT applications. In the field of Integrated Wiring, cabinets are becoming an important component of their construction.

I. Concept of capacity U

The height occupied by equipment installation in a 19-inch standard cabinet is indicated by a special unit "U", 1U = 44.45mm. U refers to the effective use space inside the cabinet, that is, the 19-inch standard equipment that can hold U, the panels of standard equipment using 19-inch standard cabinets are generally manufactured according to n U specifications,

The ing between the height and capacity of the SHIP series cabinets is as follows: the capacity of the High 1.0M cabinets is 20U, M corresponds to 24U, M corresponds to 29U, M corresponds to 33U, M corresponds to 38U, and m corresponds to 42U, 2 m corresponds to 47U.

Ii. Concept of Grounding

If the ground is grounded by signals or the chassis is connected to the earth, the signal grounding function of the device is to provide the level reference plane of some or all circuits of the device, the Ideal Grounding plane is a physical entity with zero potential and zero impedance. No voltage drop is generated when any current passes through it. Generally, there is a special grounding Copper Strip for signal grounding;

The chassis is connected to the Earth to Ensure Safe Grounding of equipment and prevent leakage of electricity to protect operators. Another function is to relieve the accumulated charge on the chassis due to electrostatic induction, to avoid discharge due to potential increase, this improves the safety of the device.

The frame and front and rear door panels of the SHIP series cabinets of the boat group reserve standard grounding columns and grounding holes. You can connect them with wires when needed. The grounding column type is M6 and the grounding hole size is. 6.

The standard color of the grounding wire shell is yellow-green. The standard configuration of the standard Cabinet does not provide the grounding wire. If you need it, you can order it separately. If not specified, the section of the grounding wire provided by the SHIP series cabinet is 2.5 square meters.

Iii. Differences between network and server cabinets

Both network and server cabinets are 19-inch standard cabinets. server cabinets are used to install 19 "standard equipment and non-19" standard equipment such as servers, monitors, and UPS, there are requirements on the depth, height, and load-bearing of cabinets. The width is generally 600 MM and the depth is generally over 900MM. Due to the large amount of heat dissipation of internal equipment, the front and back doors are equipped with ventilation holes;

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

Iv. Differences between racks and cabinets

They are used to place 19-inch devices, but the racks are open. There is no door between the front and back of the rack to facilitate the installation and construction of related equipment, but the dust prevention is poor, higher requirements on the external environment. The load-bearing capacity of the 4-column rack is greater than that of the 2-column rack. The accessories of the 2-column Rack are both cantilever and fixed at 2 points. The mounting method of the 4-column rack accessories is the same as that of the cabinet and fixed at 4 points, the cabinets are closed to protect internal equipment.
